PS1 backups on PS3 - editing PS1_rom.bin?
Hello. First, I don't know if this is the right section to post this... somebody will move it if it's not, I think. Anyway, I don't have great hacking or developing skills, let's say I don't have any, but it's been a while I've been looking for a way to run PS1 backups (or homebrew) on my jailbroken PS3.
This machine has a great PS1 emulator inside it, after all Sony made it, so I thought that it'd be better to use that, instead of writing/porting another emulator like some people are doing. Nobody seems to be really interested in that, so I've been doing some research myself, as far as my knowledge goes.
So, to the point, I tried swapping the bios in ps1_rom.bin, and now when I boot a PS1 game I don't just get the "Sony Computer Entertainment" PS black screen, but the white one with the red square too. Not only that, but if I eject my disk I even get to the Memory Card/CD player menu, and I can even use the PS1 cd player to play audio cds. And if I put a backup inside, it even sees the tracks (from the cd player). Guess what, it doesn't boot though! And the menu becomes really slow just like a real PS1 would do.
I think this is useful to know, because it means that the disk you put in is still mounted and the emulator sees it, and now it's the PS1 bios doing it's own security checks I think, not the PS3 software... right? So I was wondering, does anybody know (if it's possibile) what to edit inside the PS1 bios so that it doesn't check anymore?
