Proposal: Retro Computing
Wish I had my answer to this from the last Retrocomputing proposal. But basically, yes, all retrocomputing hardware and software should be allowed.
Many of the consoles shared hardware components with contemporary computers.
Some games were different on different platforms. For instance, the folks over at the Arqade community might not know this about Ultima I: "The original (non-remake) Apple II version uses an undocumented 6502 opcode that makes it impossible to hit the alien ships to become a Space Ace when using a 65C02. (The fix is in file "FGT3". Change the bytes at 74D1 to 46 43 45 43.)"
I say yes, if only because of the MAME/MESS connection. Resurrecting or emulating old consoles uses very similar techniques to resurrecting genera purpose computers, so as long as this aspect of the topic is respected I think we are good.
Not to mention that managing to play a game on any emulator, or loading a game onto some old tech, is often a really good soak test. One of the first things I load on an old computer is WUMPUS.
