Hi, this the CHIP-8 Emulator I have programmed for the Sony PlayStation, using my development kit (the PSXSDK). All instruction and information included. For who does not know what CHIP-8 is, read the Wikipedia article Download it here! Source code is included. Enjoy!
As Haunted said, amazing work. Too bad that there is no bigger interest for ps1 scene. Anyway, if you are interested a while back I made a Chip8 game called SNAFU. I can attach it here if you want. There is an active Chip8 thread on emuforums with new software so you can check that out. Also, there is Chip16, a community supported system which is something like Chip8 V2.0, could be worth a shot emulating in on PS1.
