Then it must be some issue with retroarch and specific ps3 models? I have one of the fat ones made in Japan during the launch in 2006 with PS2 hardware, and running Rogero’s CFW 4.46
If you want me to do any tests or something let me know. I have done these tests isolating the rom completely, I made a new folder with just that one rom, and tested all 3 PC FBA, FB Retro, and RetroArch with the same file.[/quote]
It has nothing to do with that - just with the ROM.

This is my MD5 checksum.[/quote]
My MD5 is different, but that might be due to slightly different compression. Check the CRCs for every file:

edit: btw the other emu/core that works with these roms is this one: http://psx-scene.com/forums/content/fbanext-emulator-v1-0-0-ps3-released-467/ I see they mention you in the credits for contribution.
