Looking for more information about what was involved when crossing a program (like 3DO video game to Sega Mars CD)? Trying to help my buddy.
Any help would be great!
NeXTsTep had a marketing campaign "Welcome to the NeXt Level" with Sega. The result was a Sega Mars CD machine but only marketed as a component upgrade for Sega Genesis users, called 32X in USA and Super32X in other countries. This started in 1994. The CD hardware likewise was marketed couple years previously. An extension ram cartridge was required as no buffer was present on the Mars CD machine. This resulted in D.I.Y. construction of ram on a cartridge for some form of buffer by most programmers and hobbyists. This is typical in most computers before 1995 with limited ram (SuperAMS, Macintosh II series, MSX and others).
How could these video game programs and other software a-like be crossed over so quickly, especially with such extreme hardware differences and memory systems. Doom for example was crossed to: MS-DOS, 3DO, Super Nintendo with FX chip, Atari Jaguar, Mars 3 megabyte cartridge ROM, and PowerPC Macintosh. How is this possible?
Looking for pictures regarding the crossover system with X, square, circle and triangle symbols. Property of this system was later used for the PlayStation video game hardware application, as can be clearly seen on its gamepad controller along with the colors. I think a similar system was used on a Indigo Workstation (think it used a Sun O.S. or Irix).
Thanks again for any help.
