| Rescue on Fractalus! | Atari (GCC) | 1984 | The 3 known prototypes each contain 2k of RAM. This expensive RAM was the most likely reason Atari decided to cancel the release of this cartridge. One of the cartridges is labeled 'Behind Jaggi Line'. The real-time fractal 3D graphics are rendered at a blazing (by 1984 standards) 6fps. | labelimageminimize |

| Gauntlet | Atari;US Gold (Hewson;Graftgold) | 1991 | Interviews with multiple programmers mention Atari 7800 and there was a at least one demo cart sent to a UK magazine that was favorably reviewed. | labelminimizeminimize |
| Rampart | Atari (Imagitec Design) | 1991 | CX-7892 Documents indicate this game was nearly ready for publishing when canceled. Payment to the developer also stopped. There is but one known prototype, and it is not from a nearly publishable version. [Zerothis] | labelimagesubject |

| Klax | ResQsoft Productions (Atari) | 1992 | CX7888. Planed by Atari for a 1992 release in North America, NTSC. Only 10 of the original prototypes exist, giving this game an unofficial rarity of Unbelievably Rare. It is presumed that 'DAD' is David Dentt's initials and 'JAH' is Jerry Huber's. The most notable feature that reveals this game to be unfinished is the missing sound effects and music. The plan was apparently to use the same sounds that were used in the [game=#16594]Atari Lynx version[/game] rather that get them directly from the [game=#948]Arcade version[/game]. This was probably because Greg Omi and LX Rudis had already done a lot of the work required in their excellent effort to get the Arcade audio in formats acceptable for systems more limited than the Arcade system. Still, the Lynx's audio ran on a Mikey chip (4-channel, 16-bit, 16MHz custom CMOS), it would have been quite an accomplishment to get the same audio running on the 7800's Pokey chip (pseudo 4-channel, four 8-bit/or two 16-bit/or one 16+two 8, used the 7800's 1.79MHz CPU) which was not built into the 7800 and would have been included inside the cartridge itself. As it stands, the code of the game was ported directly from the [game=#948]Arcade version[/game]. Eventually a reproduced of this game was released by ResQsoft in 2002. They sell reproductions of this game in a box with instructions, manual, and an interview with the programmer. CX7888. Planed by Atari for a 1992 release in North America, NTSC.

They sell reproductions of this game in a box with instructions, manual, and an interview with the programmer. The code has several bugs that sometimes prevent the game from booting on the 7800. These same bugs will freeze the game often in emulators. | labelimageminimize |
| Pit Fighter | Atari (Imagitec Design) | 1992 | CX7891. Believe it or not, an actual port of the arcade version of [game=Pit Fighter]Pit Fighter[/game]. Hard to image what code or data the two games actually share. So far no prototype cartridge of this game has been found. This game was found on a hard drive of a used computer purchased from a former Atari employee. [Zerothis] | labelimageminimize |
