I have DMS4 Lite chip with ToxicBIOS 1.2 on my V5 or V6, can't remember which. Anyway, My PS2 has a very hard time playing PS1 backups. I have made backups of Resident Evil 1 and 2, MGS and Overblood. So far, only Overblood works. The others get to the PS1 logo screen where it says Sony Computer Entertainment America, then it goes to a black screen and stays there forever. All the original discs work just fine. Anything I can do to make the others working?
