PSX Bios Question

FrostyWolf · May 27th, 2006

Does any one know the diffrences between these bios versions?
DTLH3000
DTLH3002
SCPH1000
SCPH1001
SCPH3000
SCPH5000
SCPH5500
SCPH5502
SCPH7000
SCPH7001
SCPH7003
SCPH7502

And as to which one would be best for running with a emulator?

DTLH is the Bios from the Net Yaroze, SCPH is from
the regular PSX, the difference is not so great, some Bioses are for PAL and others are for NTSC consoles.
For your other question, the best bios for running the emulator would be BIOS from your psx.

as far as i know, there isnt a difference in what BIOS you use. i've heard that legend of dragoon requires SCPH7502 to run properly, but i have no idea.

in other words, it doesnt matter. use what you like. or what came out of your PSX

Yes it does indeed. I have no idea why, but LOD requires that BIOS. In ANY emulator. I don't think anyone else knows why either, but my guess is maybe slight errors in the BIOS emulation? Because LOD will actually work fine on a version 1 PSX. Funny, eh?

what about SCPH7502(41a)? The supposedly updated version of SCPH7502. (I think it was also some type of dev BIOS)
