CHIP-8 emulator for PSP

Hi there guys

 

DreamChip is a chip8 emulator ported to the psp by me.

 

for anyone wondering what a chip8 is look here : CHIP8 wiki

 

I bet some of you never thought this project would ever get as far as a release

 

I took the initiative to port a Chip8 emulator (unamed) made by TJA of emutalk to the psp.

 

It uses sdl for input, sound and gfx.

 

It runs at full speed (i think ) and compatibility seems good too

 

I have included Some pd roms with the release, although as far as im aware all chip8 games are pd now.

 

I would like to say a special thanks to Hardhat, who taught me a hell of a lot of sdl and helped me with some stupid mistakes i was making a long the way

 

Due to my psp being briked i would like 1 beta tester for this emu, as i am sure input is working now but have being unable to test it myself.

 

Enjoy

 

Note : This emulator is currently hardcoded to play a rom named "ROM" in the /rom directionary.... to play another rom just rename it "ROM" and replace the current rom in the folder.

 

Source code will be released soon, very messy and a few things need changing before source is released.

 

Cheers
