Uses a higher resolution than the platform's standard.
The first video game about High resolution was released in 1978.
Note that some early computers used a single resolution as the standard one plus lesser resolutions. Advanced programming techniques or non-standard hardware could sometimes coax higher resolutions than the hardware designers intended. Modern computers however, are designed to accept new hard ware and games for them definitely should not be using this tag.
For the Apple ][ platform, this means the so named "Double Hi-Res" 6 or 16 color graphics mode (560x192x6/16), not the standard "Hi-Res" (280x192x6) mode nor the "Hi-Res" black and white mode (560x192x2). For more information see the Apple ][ platform entry.
For the Apple ][GS platform, this means 640x200. The standard resolution is 320x200. For more information see the Apple ][GS platform entry.
For the Atari 5200 platform, this means 320x192 and any color depth. 160x192x16 is the standard, with 256 colors being a tricky option. 320x192x3 is the technical upper limit, but the 5200 can mix modes on a single screen to sneak 256 colors into the hires picture. For more information see the Atari 5200 platform entry.
The Atari 8-bit platform is nearly identical to the 5200 in terms of highest resolution. However, it is held to a higher standard since it is a PC. 320x192 only if it uses 9 colors or is mixed with a 16 or 256 color mode. For more information see the Atari 400/800 platform entry.
For the Gamcube platform, this means 640x480p, 720x480p, 720x576i, modes. 640x480p games are marked "progressive scan" in the US. The standard resolution is 640x480i. For more information see the Gamecube platform entry.
For the Megadrive platform, this means 320x448. The standard resolution is 320x224. For more information see the Megadrive platform entry.
For the Super NES platform, this means 512x448. The standard resolution is 256x256. For more information see the SNES platform entry.
Tag is not for most PCs. Most consoles for nearly all games use a standard resolution. Sometimes authors coax or use higher ones from the platform.
