Why stop there?????
These emulators are so small I put 20 of them on my DOC and have been playing for about 2 weeks. I have an IDE card that also has a joystick port so I run my cdrom and play the games off of there. You must have a joystick as playing console games sucks with a keyboard.
I have an nes, snes, atari 2600,7800 sega, genesis MAME<-multiple arcade machine emulator, Rane, neorage, and many more playing off of the machine.
Lets see how far we can take this. I think this thing could be an ultimate console for 8 and 16 bit video games
I am currently building a front end that starts up from the autoexec when the WS is turned on. It is a menu that has joystick support. it lets you choose what emulator you want to play. I am even making it configurable so users can add or delete menu items.
