The distribution contains a customized 3DO Interactive Multiplayer emulator on the 4do core under Retorach with BIOSes plus 3 original games: Wolfenstein 3D, Star Control II, GEX.
3DO Interactive Multiplayer (or just 3DO) – a game console, released in 1993-1996. Panasonic, Sanyo, Creative, and Goldstar, originally developed by Dave Needle and RJ Mical of the New Technology Group. The idea of creating a console belongs to entrepreneur Trip Hawkins, who is the founder of EA Games.
At the time of release, the console had very advanced hardware capabilities: a 32-bit ARM60 processor with RISC architecture, operating at a frequency of 12.5 MHz; two graphic coprocessors; 16-bit digital signal processor and special mathematical coprocessor. All additional coprocessors were developed specifically for this console. Also, the console had 2 megabytes of RAM, 1 megabyte of video memory, and a two-speed CD drive. It was possible to simultaneously connect up to 8 joysticks (in the original way – in a chain, one connects to the other). In addition to using specially developed software, the console could play CD-audio (including CD + G support), view Photo CD and Video CD. To play the latter, it was necessary to use a special expansion card for decoding MPEG video (produced only for the American Goldstar model and Japanese Panasonic). However, only a few games took full advantage of the console’s potential.
