For arduino and PIC12F675,
I ported the hardest one across to PIC in ASM first, that being the PAL PSOne with extra region check ... so the rest will be a cinch! But it doesn't support Genuine imports, only burnts. I will add the functionality soon, but if you only play burns and originals from your own region its all good. Very reliable.
