I don't like multiple versions under the same platform either. I would support a PCjr+Tandy 1000 platform (as opposed to separate PCjr & Tandy 1000) simply because the PCjr library is so tiny and on a technical level, PCjr can be or could be upgraded to full Tandy 1000 compatibility using more than one practical method. But, this would still have the double entry issue for game released separately for PCjr and Tandy 1000. To aid in the discussion and future classification games for the three systems, I've made an extensive (but still not comprehensive) break down of Tandy, IBM-PC, and PCjr differences in the Tandy 1000 group. I did not, for instance, individually list the 39 memory differences with address ranges, functions, attached hardware, port names, port types, if they are different for only one or for both of the other systems, and which of the 39 do or do not apply to each model in the Tandy 1000 series, because they are all essentially the same issue; direct memory access can break compatibility the way a target can still be obliterated by shotgun that misses the bullseye. I also haven't delved into IBM's Micro Channel Architecture which I believe was never successfully cloned in a PC compatible except by Tandy for some models in the T1K series (and I don't think MCA ever directly effected games).

Tandy compatible modes did come later as the platforms diverged (configuring that allowed the IBM executable to run correctly on Tandy 1000). Also, games sometimes had Tandy compatible installation (a Tandy 1000 executable was installed). Both of these options came in the same box and used the same disks.

Tandy compatibility methods (strictly Tandy 1000 and not IBM-PC compatible, FAT executable, separate executable on disk, separate package, separate disk versions in same package, separate boot disk with shared data disks, IBM-PC game claims Tandy 1000 compatibility in specs/reqs, versions differ in compatibility like Prince of Persia, combinations of these)

*In cases of Tandy DAC, this presumes other DAC hardware does not have superior DAC and voices. Some might. It is time consuming to determine which hardware applies. But, Tandy 3(4)-voice in this list is valid.

EDIT: The search links have been added to the tandy1000 group description.

That is correct. Different hardware, different graphics modes, different sound modes, different boxes with different versions inside, and in some cases on a very low level differences in assembly code. Running a Tandy 1000 executable on an IBM PC running DOS very likely rusults in game breaking bugs if it even runs at all. OS intall limits are also common. The closest match to Tandy 1000 is the IBM PCjr, and these are not 100% interchangable. Both platform diverge from there.

I am not a Tandy specialist, but wasnt the Tandy just another PC clone, which could be subsumized under the standard MS-DOS entry for the game. So that the tag "tandy1000" means that there was a "special" Tandy version or it would run different on Tandy 1000. I guess we have discussed a similar topic many many years ago... still confusing. A platform I pretty much ignore and subsumize under "PC". Having 2 MS-DOS entries is very confusing with only the tandy1000 tag, thats for sure.

Thanks, but I don't think "Tandy DAC" is "DA Converter". Like the Covox Speech Thing, "Tandy DAC" and "DA Converter" are both listed separately in the same specs for some games.

It just so happens I'm currently curating all the Tandy DAC game I can find. Tandy DAC is so name because it added a Digital to Analog Converter voice to the existing "Tandy 3-voice" hardware.

I'm tagging games that work with ScummVM. Also updating engines (which us how ScummVM funtions, recreating game engines). 'Duplicates' can happen when the game made with an engine then re-released with an entirly new engine. Has separate DOS, 16-bit Windows and/or 32-bit Windows versions not previously entered. Has separate Tandy 1000 and MS-DOS versions (the two had enough differences to warrent this for some games). Also, I've separated OS X and classic Mac in some cases (different game engines). All that said, it is possible I've erroniously duplicated a game or 2, so i'll recheck the entries you've listed.

www.uvlist.net/game-218527, separate Tandy 1000 version
www.uvlist.net/game-218523, oops! I erroniously duplicared, sorry
www.uvlist.net/game-218522, OS X updated re-release. Not OSClassic compatible as is my understanding
www.uvlist.net/game-218507, oops! also duplicared
www.uvlist.net/game-218508, ok, this one seems to have been a double submit, which happens rarely when there are connection issues.

Oh man! 2/5, satistics make me look really bad for this one :(

Platform Tandy has a release date of 1993. Not sure how that year got there.
http://www.uvlist.net/platforms/detail/72-Tandy

Tandy is a complicated matter, but I think that this platform is meant to be for the "Coco / Color Computer" series. If thats so the release date would be 1980.

Lots of different architectures were made by Tandy.
[list]

Tandy 1000 & 2000 were PC clones with 8080, 8088, 8086, 80186, 80286, or 80386 CPUs. More accurately, it was a PCjr clone and while it was 100% compatible with the PCjr it lacked the cartridge port and full compatibility with other IBM-PCs. Most developers, if they bothered with Tandy 1000 compatibility, would make a selectable mode for their program to run on it. In particular, these programs often asked the user to select "Tandy Sound" and "Tandy Graphics.". Some actually fully ported their software and sold the packages separately or (rarely) included both disks in the box. Robot Odyssey: Special Edition was ported to the Tandy 1000 and sold separately. They Tandy 1000 and King Quest game (Developed for the PCjr) helped make each other successful. It was an unheard of game until the Tandy 1000 was released and then IBM abandoned the PCjr leaving no other way to play the original King's Quest. Despite later IBM clones having the ability to play it, only the Tandy 1000 would allow the full 16 color graphics to display properly. UVL does not have a Tandy 1000 platform.

Tandy GRID were PC clones

Tandy TRS-80 had a Z80 CPU. There were Model I, Model III, Model 4, Gate Array 4D, Model 4P, Model 4D in this series. Not compatible with the 1000. UVL has a TRS-80 platform. Robot Odyssey: Special Edition unrelated and not compatible in any way whatsoever and should not go in this platform (but there might have been a TRS-80 version, not ruling out the possibility) UPDATE: IF there is a TRS-80 version (note that is a big "if"), then it is specific to the Model 4 or 4D. The only reason this would exist is due to the 1984 presence of so many TRS-80s in schools and probably used the "Robot Odyssey I: Problem Solving Game" title variant like the Commodore 64 version.

Tandy Color Computer (Tandy CoCo). UVL has a Tandy Coco platform. Had a 6809 CPU, it was not compatible with the TRS-80 or 1000 models. However, the company confusingly called it the "Tandy TRS-80 Color Computer". Others avoid calling it this because it is so confusing. They dropped the "TRS-80" from the label of the CoCo 2, 3, and 4 models. Robot Odyssey: Special Edition unrelated and not compatible in any way whatsoever and should not go in this platform (but there might have been a TRS-80 version, not ruling out the possibility)

Tandy Zoomer. A hand held IBM-PC clone with an NEC V20 CPU (Intel 8088 clone). It beat the Apple Newton to market as the first fully functional PDA, it also beat the newton for worst hand writing recognition, slowest performance, and worst market flop. UVL does not have a Tandy Zoomer platform.. UVL now has have a Tandy Zoomer platform

Tandyvision/Tandyvision One Computer. Tandy sold authorized clones of the Intellivision plus keyboards and cassette decks for it. They marketed it as a Entertainment Computer System. They however did not make or repackage games for it. Sears made the Sears Super Video Arcade, another authorized clone, but also made and repackages games under their own brand. By the time Mattel Aquarius was released, Tandy was no longer selling the Tandyvision but their Tandyvision One computer (keyboard and drive added) was fully software Aquarius compatible. UVL has a Both the Intellivision and Aquarius platforms and Tandyvision games should go there.

Tandy-12. A series of augmented reality games. They could be classified as board games. Simular to Stop Theif, there was an electronic computer with 12 multicolored, numbered, lighted buttons (an oversized keypad of sorts, it also served as a display) and 5 normal buttons and a switch. This unit was programmable and was pared with traditional game elements of each game.

Some external hardware was interchangeable between the different Tandy computers. Such as keyboards, mice, and joysticks. There may be other Tandy machines out there. I expect most of them are clones of something else. Tandy corporation most likely investigated cloning all their competitors platforms, including Sinclare, Commodore, and Apple ][, They may have done an MSX compatible as well.

The Dragon 32, Dragon 64, Micro-SEP, Micro Color Computer (6503 CPU), MC-10 (6503 CPU), Tomcat TC-9, Tomcat TC-70 (68070 CPU), Delmar System IV (6800 CPU), Peripheral Technology PT68K-4 (6800 CPU), MM/1 (68070 CPU), AT306 (68306 CPU), and Sysdata Tcolor (6503 CPU) computers were vaguely Coco clones. They are so different I don't think they should be considered the same platform.

Coco Clones with unknown compatibility:
The Sampo Color Computer
Prologica CP400 Color
Varixx VC50
LZ Color64
Dynacom MX1600
Codimex CD6809
Microdigital TKS800

EDIT: Tandy did do an Apple ][ clone. It was an add in card for the Tandy 1000 that converted the T1k to an Apple ][ machine.

EDIT2: Nobody cloned Commodore except Commodore. The whole idea behind cloning is to assemble and sell 'the same system' cheaper that the original manufacture does (or the same price and offer other profitable services the original company does not or can't). Nobody could compete this way with Commodore due the vertical marketing (owning most of the process from mining silicon, shipping it, designing chips, manufacturing chips, designing the computers, building the computers, and finally shipping them to stores). When prices rose in any step of the process, commodore absorbed it in the other steps and didn't raise their shelf prices. Other companies had no choices except lose money or pass on the extra cost to their customers. I'll wager highly that there are no Tandy 64s. The 'Commodore Clones' are hobbyist upgrades or produced by companies that had legal rights to do so (1st party clones, Commodore clones by Commodore).

Update:
Other Tandys that are not TRS-80 I/III/4 compatible:
TRS-80 Model II (Just plain different)
TRS-80 MC-10 (The Matra Alice was based on this system. EDIT: MC-10, Alice, Alice 32, and Alice 90 are in the same family and not software compatible with Coco, nor TRS-80 Model 1/3/4, not any other Tandy machines)
TRS-80 Model 100 (a Kyotronic 85 clone)
TRS-80 Model 12 (later incarnation of the Model II)
TRS-80 Model 16 series (later incarnations of the Model 12)
Tandy 10 (a unique Intel 8080 based computer)
Tandy 200 (later incarnations of the Model 100)
Tandy 6000 (later incarnation of the Model 16)
Tandy Pocket Computer series (Casio Calculator clones)
TRS-80 Pocket Computer 1 / RS-80 Pocket Computer PC-1 (Sharp PC-1211 clone)

Scrabble & Scrabble are different versions. Scrabble is for the Tandy 1000 platform. I don't have the capability to make a screen shot for it. Looking at the screen it is obviously a different program and not merely shovelware.
Same with Monopoly & Monopoly

I have been multiple CPU adding tags based on:
The minimum and recommended specs. Because many times, but not always, minimum specs aren't true
The specs of different releases are different.
The game actually does not run on some variants of CPUs. There are a number of 8088 and/or 8086 games that do not run on 286, 386, 486 but run on Pentium or later CPUs.
The game has settings or includes variants for multiple CPUs. I recently added 8088 and 8086 tags to a 286 game because the configuration has a complete Tandy mode that will run the game on 8088 and 8086. Normal mode is indeed limited to a 286 or better. You can't just turn down the settings of normal mode to make it work.
The publisher listed multiple CPUs on the box. Minimum or better is usually assumed, so the publisher probably had a reason to list each CPU variant.
Searching works better if users do not have to plan a complex syntax to confirm witch games run on which hardware. The Tandy 1000 group has some examples of complex search syntax to work around the hardware complexities. Should users really be required to do this for CPUs as well?

But, I will stop if needed.

I would guess that it's weird lingo for non PC speaker audio, or in other words, supporting external speakers, even if PC speaker isn't technically digital. Really bad way to present it, to be honest.

Looking around a bit more, I ran into Tandy DAC, so it might be reference to that. Related to that was PC speaker emulator ("Jeffrey Hayes' Tandy DAC Sound Package") or something like that.

The more I learn about the Alice 32, Alice 90, and TRS-80 MC-10 the more I think it should be a platform separate from TRS-80 and Tandy Coco. They all use the 6803 CPU which is not Z80 nor 6800, like the TRS-80. 6803 and 6809 are in the same CPU family. But the Alice 90 is called a Tandy Coco clone. I somehow doubt the a 6803 machine would run 6809 software. Information available on line is contradictory. I simply don't know enough to know how to group these.

dandyboh has mentioned this platform before.

The original Matra Alice was a straight TRS-80 clonebased on the TRS-80 MC-10 and developed in cooperation with Tandy
The followup computers
Matra Alice 32
and
Matra Alice 90
Were also based on the original Alice but contained custom chips (mainly the video processor) meaning many Alice 32/90 games will not run on Tandy computers. Also, they use SCART and French TV signals, so again, not on Tandy.

Alice 32
CPU: Motorola 6803
8k RAM
8k video RAM
EF9345 video chip
16k ROM
AZERTY keyboard
built-in assembler (like Apple ][)
RS-232C serial interface
Cassette interface
Péritel video out
Expansion slot

Alice 90
32k RAM
CPU: Motorola 6803
8k RAM
8k video RAM
EF9345 video chip
8k ROM (Microsoft BASIC)
full sized AZERTY keyboard
RS-232C
Cassette
Péritel video out
video in (graphics could be overlayed onto video)
Expansion slot

They were apparently popular in French schools.

MC-10 and Alice hardware are not related to Tandy Color Computer (Coco) nor TRS-80 Mofel 1/3/4.

A lot of hardware back in DOS days had Tandy compatible modes, and a lot of games had modes for both Tandy hardware and regular IBM-compatible hardware (sound and/or graphics modes).

Windows, iOS, Android and "Browser" are platforms that easily surpass 1000 games per year at the moment. Not based on UVL figures of course, but we know we lack in these categories (while Linux is relatively well documented I guess).

I also assume that some highly popular older systems like the C64 might have a year or two with over 1000 games (again, not in UVL so far - but just looking at the total games number of 24500 of Gamebase64 does let me assume this)

Tandy 1000 and PCJr games are placed under MS-DOS platform (discussable but I personally think thats good, because in the world of games I consider them belonging to the IBM compatible family). Explain the special versions of the game in the main description, tag them as pcjr, tandy1000 or create new tags for those special cases, but I don't like a situation to place two 'same' King's Quest games under the MS-DOS platform. When this discussion becomes heated I would rather agree creating a new PCJr platform and split the games from DOS than having it both under DOS as 2 entries.

Edit:
Will post the two links to the deleted logs with tags and description to the two deleted KQ games here so they don't "vanish" for possible restoring purposes later:
https://www.uvlist.net/admin/logs/?type=game&id=246779
https://www.uvlist.net/admin/logs/?type=game&id=246780

So is this particular entry mislabeled for DOS instead of Tandy or what?

Problem with Xbox references. Here's an example using Maison de Maou
This is valid reference URL: http://marketplace.xbox.com/ja-JP/Product/メゾン-ド-魔王/66acd000-77fe-1000-9115-d80258550bfc
Unfortunately the URL that UVL gives back for it is not: marketplace.xbox.com/en-US/Product/game/66acd000-77fe-1000-9115-d80258550bfc

This is probably because the game is region restricted, but it unfortunately corrupts a perfectly valid reference.

Many of the King's Quest games came in multiple engines. But they also came in Tandy 1000, PCjr, and DOS/PC compatible specific versions. these are not the same games. In fact, Some of Sierra's own compilations on CD include up to five versions of the 'same game'. They did not make a CD-ROM compilation with DOS and PCjr games because they intended for PCjr owners to play one version and not the other. If you don't believe me, try running a CD-ROM on a PCjr. They included multiple versions because they are different. The SCUMMVM team agrees, the machine specific games are treated distinctly by that software. I put a lot of effort into cataloging each separate entry including loading up many versions of my Sierra games both individual and from compilation to multiple systems and multiple emulators checking to make sure the games were not just 1:1 copies in different boxes and/or with different system requirements stickers.

Also, UVL users besides myself may have marked the individual versions as played/owned etc. And marked ranking of the individual versions. These were lost.

I rather not do all that again so please restore each entry, thank you.

Windows 3.1 and Windows 95 or larer are different operating systems. So 2 different versions of the game. Windows 3.1 in many ways is a layer on top of DOS with 16-bit capabilities. Windows 95 is 32-bit with minimal DOS compatibility to provide 16-bit Windows backwards comparibility.

Yes, a patch to make a game run on a later or even different OS is confusing. Not always sure if these are 2. It helps if the publisher or developer actually provides both exicutables since that formal-semantically makes it two differnt games. There's also often cross-platform features. Such as a pure DOS game that is able to detect that Windows is running and offer the Windows Sound System (or Microsoft Sound System) as a sound card option. And numerous DOS games offer Tandy Sound and/or Tandy Graphics while some use separate executables for each system and still others use specific disks (sold separatly or in the same box) for each system.

[[quote:- Maybe that "Coleco" should be renamed as "Colecovision" as it's the real name of the machine, and "Coleco" is another company.]]
<b>Co</b>nnecticut <b>Le</b>ather <b>C</b>ompany, (Coleco) was a leather a crafts manufacture who decided to diversify and sell kids toys. Their <i>Cabbage Patch Kids</i> dolls were most successful.

I used numbers another site who's dark name shall not be uttered here. I would hope UVL editors and new would bring our DOS and Windows titles up to par.



By all means, please add up platforms and contribute their top year to this list.

Currently, DOS gets the tortoise win. Games were made for DOS for a long time at a relatively stead bell curve. I was actually shocked to find no years that exceed 1000. Other PCs tend to build slowly to a spike and drop off at a similar rate as their rise. Not sure about Windows yet, it seems to have rose to a peaked and is dwindling. But it's not finished yet so we shall see. Many Consoles tend to jump to a high number in their 2nd year (no where near 871) and remain high for a very short time an dwindle off a bit before a sudden discontinuation (except for the occasional homebrew or late release).

Just in time! :-)
Here is the list of platforms I was building too:

APF IMAGINATION MACHINE http://en.wikipedia.org/wiki/APF_Imagination_Machine
<s>ACETRONIC MPU 1000 (Interton VC 4000 clone)</s>
ACTION MAX (VHS shooting - Worlds of Wonder Entertainment) http://en.wikipedia.org/wiki/Action_Max

<s>Cassettevision (Epoch)</s>
My Vision (Nichibutsu ) http://en.wikipedia.org/wiki/My_Vision

If someone else has his own hardware list, please contribute!

note:
Those urls are now real links, isn't it cool? ;-)

Last week the following 11 new platforms were added :
iPhone , Sega Pico , Game Master, PowerTV, Texas Instruments Calculators, Tiger R-Zone, PLATO, Leapster, Tandy Zoomer, Zeebo and a generic platform for all the one-hardware / one-game cases.

Just added some more platform images:
Apple Pippin, Casio PV-1000, CD-I, Gameking, Gizmondo

UVL now supports the following 7 new platforms :

Game Wave
HyperScan
MicroBee
Tandy VIS
PlayStation 4
Vii
Xbox One

Thanks for the submissions, I'm now reviewing all of them, plus a list of platforms I had by myself.
Stay tuned :)

-edit-

I'm going to add:
- iPhone
- Sega Pico, 1993, 4th generation, designed for young children (ages 2-8).
- Game Master, 1990, handheld system by Hartung, Germany. 4th generation. http://en.wikipedia.org/wiki/Hartung_Game_Master
- PowerTV www.powertv.com/developers/PowerTVOSDocs.htm
- Texas Instruments Calculators
- Tiger R-Zone
- a custom/generic platform
- PLATO
- Leapster ( not Leapster 2 : "All previous Leapster games play on the Leapster 2, and all Leapster 2 games play on a Leapster" )
- Tandy Zoomer / Tandy Z-PDA
- Zeebo

And found these too:
- ClickStart http://en.wikipedia.org/wiki/ClickStart
- digiBlast http://en.wikipedia.org/wiki/DigiBlast#digiBlast
- Didj
- Entertaible http://www.extremetech.com/article2/0,1697,2010102,00.asp
- HyperScan http://en.wikipedia.org/wiki/HyperScan
- Zune

These do need more study:
- Handheld console with 20 games embedded. www.segaretro.net
- Java
- IQue Player ( maybe just a tag, as it is now? )
- Pandora
- HP-** - we already have HP-48 and HP-41 . Shouldn't we merge these two and use tag for all the other HPs ?

A somewhat extensive update has been made to the Tandy Color Computer platform and related tags. But I suspect there are at least 500 more titles. Also, we are not yet near utopic completion for the titles already listed.

Fuzix, Linux for 8-bit systems
Runs on Amstrad NC100, Amstrad NC200, Amstrad PCW8256, Atari 520ST, Dragon Nx32, Epson PX4/4Plus, Memotech MTX512, MSP430FR5969, MSX, Multicomp09, N8VEM-MarkIV, P112, SocZ80, Tandy CoCo 2, Tandy CoCo 3 (6809, very usable), TGL6502m, TRS80, V65, V68 - 68K, Z80Pack, Zeta v2, and ZX Spectrum 128K so far.

GPL2 + LGPL componets

[size=+2]29 games[/size] so far
And this is odd, it has a CP/M emulator

The effort is lead by Alan Cox and was announced by Linus Torvalds. Apparently, while the kernel team was arranging discontinuation of their involvement in ELKS (embedded Linux kernel, focused on 8086 systems) Alen Cox launched the Fuzix project (influenced ELKS) as response to SystemD and specially Kdbus as the trigger. Kdbus was killed but Fuzix lives on. While there is a great deal of porting to classic 8-bit systems, Fuzix is actually extremely useful in that archaic (cheeper than dirt cheep) hardware can be put to real use in the modern world. Also those n-in-1 TV systems, for example, could be turned into full gaming consoles, internet terminals, steamboxish streaming recievers, etc.



EDIT: I have created a FuzixOS group and added games under the custom platform temporarily.

This is the same when a Steam game is not available worldwide, I think.
Maybe the "region" can be deduced form the code itself? 66acd000-77fe-1000-9115-d80258550bfc

The remaining ones without types:
Tandy Zoomer -> handheld (PDA?)
R-Zone -> handheld
PowerTV -> set-top box (console)
Plato -> mainframe and a computer
OS/2 -> computer
Interton VC 4000 -> console

Memorex VIS / Tandy VIS / Memorex MD2500
CPU: AMD [email protected] MH, 80287-12@12 MHz (math co-processor)
Graphics 640x480x24-bit color, 512k video RAM
Sound: 16-bit Stereo, headphone jack, microphone jack
Media: 2X CD-ROM
Memory: 1 MB RAM
Storage: 32k flash (removable)
Input: 2 Wireless IR Joypads, PS/2 mouse (optional), PS/2 keyboard (optional), PS/2 Joypad (optional)
Network: 2400 Baud Modem (upgradable to 4800)
SMRP: $699 (later $399)
About 70 titles (at least half of these are games)

Released in December 1992 it was one of those Multimedia systems (Like CD-i). It has firmware based on Modular Windows (a subset of Windows 3.1 that eventually became Windows CE). The software is not at all Windows 3.1 compatible and the VIS will not load run Windows 3.1 software (Note, Sega Dreamcast is similarly based on Windows CE). Modular Windows itself ran on a full version of MS-DOS 3 and the '1 Megabyte' of RAM includes the infamous 640k DOS limit. The ADAC-1 based video hardware was made by Cirrus Logic and allowed for RF out, S-Videoout and RCA style AV out. The sound chip by Yamaha was Adlib Gold compatible but not Sound Blaster compatible.
VIS is short for Video Information System. The Tandy VIS is simply a rebranded Memorex VIS. The Memorex MD2500 VIS is simply a Memorex VIS priced at $399. About 11,000 units were sold.

I think screens from demo versions should be disallowed as a rule. The same thing could be claimed about the graphics of platform U version looking exactly like platform Q version. Makes me think of the back of game boxes during the mid-eighties. You have this box that said IBM/Tandy or 100% compatible, CGA/EGA on the front, then on the back it would show Apple ][gs, Amiga, and Atari ST screenshots in beautiful colors. I'd get excited until I remembered "EGA sucks"

Not counting unrelated platforms, unplayable indevelopments, and add-ons.
Overall completion level has been raised a bit to
Linux

I would like to propose to turn current century and millennium tags to cover the range of 0 to 9 instead of 1 to 10. Effectively what the #xx variations of the their titles show. Not sure how to go about it, though. The general benefit of this is that it will cover only single century or millennium, not century+1, etc. years.

Decades (e.g. 1960s) are already in this format, so it would be good to have centuries and millenniums use the same. The tag names may need changing or we may ignore the discrepancy in the name.

I believe this oddity comes from the fact that there's no year 0. So you can't have first century starting from non-existing year (counting starts from 1, the first year of the first century is year 1, but first year of the effective 3rd millennium was 2000, not 2001).

Best solution I believe is to treat the first century as special case that it has one year less than the others. We're one year off regardless how we go about it.

As a supportive clause for the special case method, I present you with the first decade: en.wikipedia.org/wiki/0s, which is only 9 years long unlike all the others which are 10 years long.

Here's another: en.wikipedia.org/wiki/1000%E2%80%931009, the decade 1000-1009 begins on 1000-01-01 yet it belongs to 11th century, but 11th century itself (en.wikipedia.org/wiki/11th_century) begins on 1001-01-01.

The primary aim of this change would be consistency, not accuracy to the particular literal readings of the time ranges.

Gosh, that's like 1000 games behind! No sleeping till we're caught up. Move it people! Go, go, go! :)

Andrea, thanks for all the work you do here. I think I speak for everyone when I say we appreciate your administration of UVL.

I'm worried about tag flooding here ...
For example, the NES Classic tag is ok. But despite that hardware could play almost any NES we are not tagging all of them.
What about the ZX Vega, with 1000 pre-loaded games? http://retrocomputerslimited.com/products/zx-vega/about-the-zx-vega
And what about any "emulator on a chip" possibly coming in the future ?

This is used to describe a feature for several roguelikes (though it seems to be a major yet unnamed feature of all the classic roguelikes). I think it means you get exponential experience for succeeding at tasks measured by 'linear' risk _and_ to the point that you can gain much more from a given task of high risk than you could if you do the same task later when it is not so risky. In other words, it doesn't count games where you can earn 1000 xp from a monster far outside an area safe for your level 1 character to wonder into but come back later as a level 999 character and you still get the same 1000 xp reward.
For example:
LV 1 character fights LV 1 enemy for 1 XP
LV 1 character fights LV 2 enemy for 3 XP
LV 1 character fights LV 3 enemy for 9 XP
LV 1 character fights LV 4 enemy for 27 XP
LV 1 character fights LV 5 enemy for 81 XP
LV 1 character fights LV 6 enemy for 243 XP

LV 10 character fights LV 1 enemy for 0.001 XP (0 XP)
LV 10 character fights LV 2 enemy for 0.003 XP (0 XP)
LV 10 character fights LV 3 enemy for 0.009 XP (0 XP)
LV 10 character fights LV 4 enemy for 0.027 XP (0.02 XP)
LV 10 character fights LV 5 enemy for 0.081 XP (0.08 XP)
LV 10 character fights LV 6 enemy for 0.243 XP (0.24 XP)

Example that is not quick gains:
Dragon Warrior. Taking your level 7 character to do battle at Hauksness. Here you can battle wraith (60xp/17g), wolflord (38xp/80g), wyvern (42xp/100g), goldman (50xp/200g), the Axe Knight (52xp/140g). Come back at Level 29 character and get the same rewards wraith (60xp/17g), wolflord (38xp/80g), wyvern (42xp/100g), goldman (50xp/200g).

As far as tags, I think quick gains should be covered by the causes and not the result. Experience or advancement can be rewarded statically for a given task or dynamically based on the risk of said task. This dynamic reward can relate linear to risk or exponential to risk. Advancement can be set to meeting goals on a linear scale, a non-progressive linear scale (need 100 XP for level up every time), an exponential scale, a varying scale (1,4,8,10,40,80,100,400,800,1000,4000,8000), or a progressive set (two get to LV 5 you must gain equivalent points needed for LV 1 and LV 2 and LV 3 and LV 4). However, all tagging based on the result could be reduced to quickgains and make everything a whole lot simpler with the average uvl user and visitor being able to recognise the concept.

Also, I could have misguessed the definition of quick gains.

That's what I mean, TRS-80 software does not run on Alice*. TRS-80 is a z80 based system. Alice is 6803 based. Or did you mean TRS-80 MC-10? Yes, I would expect MC-10 and Alice to share some compatibility on a hardware level.

*Except BASIC. But there are issues with this between different Tandy machines sharing versions of the same BASIC and I expect Alice would have the same issues and maybe more

I can't really estimate the number of CP/M game available but will say there is at least 100 of them. This includes games exclusive to the CP/M platform. Various machines are emulated and fully CP/M capable (or use CP/M standard) in MESS.
BTW, CP/M games are an interesting animal to add to UVL. CP/M is an operating system that functions on a wide variety of platforms. CP/M really needs its own platform. Due to its heyday being so early in the history of computing. I suggest CP/M games be listed in our current catchall, DEC PDP-1 and tagged with CPM. It is notable however that CP/M software continued to be published into the 90s. Listing them in MS-DOS would be bad because many CP/M games are also available for DOS yet present a completely different gaming experience (CP/M and DOS diverged extensively over time). Of course I believe CP/M should have its own platform.

Pandora. It's a Linux, but very hardware specific.

HP 3000/e3000 series. A very, very long lived platform. 35 years! Thus a high potential for many more games than the 29 entered.

Apple ///. I actually expect about 99 games exist for this. Entirely different animal from Apple ][.

Apple I. I don't think add at this time. I suspect that Apple I games are 100% compatible with Apple ][, so just tag in Apple ][. calling the platform "Apple ][ series" has been mentioned before by me (and solves //c, ][e, ][enhanced, ][plus, and all the variants).

These platforms have fewer than 10 games each and I don't expect more than 12 to be discovered ever.

Just delete or correct the information. If that means a short review has to be deleted then it has to be. If it is from an active editor maybe ask in those cases first, but if it is just some wrong facts, delete it. Your proposal of a visual reminder seems to be more of an annoyance than really helpful.

In the end it is another request that only makes sense once Andrea is "back" and willing to implement new things. Did someone collect all change/improvement requests so far?

(For the moment I would rather have some more platforms in UVL than anything else - you know for all those which are tagged right now. I nearly deleted one or two Amstrad CPC or MS-DOS games because I thought they were duplicates, because I overlooked one entry had the tag "amstradpcw" or "tandy" and thus its meant to be a different version.)

Not to mention Flash games (strictly not same as browser games), which no-one bothers to exhaustively catalog because of the ridiculous amounts of shovelware that iOS/Android are trying to challenge.

Added some images for some platforms: Atari 5200, Atari 7800, Arcadia-2001, Astrocade, Channel-f, Gamegear, Intellivision, Jaguar, Lynx, Mastersystem, Nds, Neogeo, Nes, Odyssey-2, Odyssey, PS4, PS5, Saturn Sega SG 1000, VCS, Vectrex

Updated some low-quality images too: 3DO, PSP WiiU, Xbox, Xbox One

I'm also not concentrating on prototypes. This is something I would care of if a system has a 100% finished state in UVL and then its time to fill up with playable prototypes maybe.

Looking at the prototypes listed at that site I see that its not 1000 unique games. Most of them are prototype versions of games that have seen a normal release. Sonic 2 for example has about 10 prototype versions on that site, other games even much more.

Quite. You could add the cd 1st and then make the individual entries like I did with assassin disks and ADAM disks. In this way, other editors, including one time editors, could do some of the work for you. After all, assassins disks only have 2 to 8 games per disk (from what I've seen late) and I expect a CD would have around 1000 or more. Share the load.

Also, I've come across info that some of the ECS/OCS collections patched for AGA have individual games on them that still don't run ootb on AGA. Sometimes this is the game itself, other times it works manually but will not run from the menu/launcher interface; in either case it may or may not be possible for users to bypass this problem.

I figured that all I needed was, when creating the thumbnails, to double the larger version (the one you see when clicked), but only when too small (450x400, so the largest doubled image will be 900x800).

You can see the results here:
http://www.uvlist.net/game-18257-Alien+Breed+II:+The+Horror+Continues

This only applies to the new screenshots.
Rebuilding all the screenshots at once ( 57345 x 3 = 172K images) would kill the server, so I'm going to rebuild ~1000 images/day

note:
The thumbnails are not created after the upload, but instead when is image is first seen, so the correct result needs at least one page refresh to work correctly, but I'm going to modify this behavior.

Doesn't particularly scream out DOS, any CP/M users recognise these resolutions? Could be a Tandy IBM compatible type situation. It's sort of IBM compatible with a type of DOS derivative or DOS-like clone.
