SCPH-5502

[Sune]

When starting up pSX with SCPH-5502, it displays these error messages and halts:

translate_address: illegal physical address 011a3800

r3000: executed illegal opcode

Maybe my file is bad, can anyone else verify this?

That definately looks like a corrupt/incorrect BIOS file...

ePSXe didn't like it either, so it's been canned.

Thanks!

I got a large bios pack.
Most of them were junk.

Here's what i verified to work:
(haven't completely tested them all but atleast theys start the emu)
SCPH1001 wow, what a secret ROFL! -sorry bad joke.

SCPH-1001 is an USA (NTSC) BIOS. *recommended default

SCPH-5500 is a JAPAN (J/NTSC) BIOS.

SCPH-7000 is a JAPAN (J/NTSC) BIOS.

SCPH-7001 is an untested ENGLISH (?) BIOS.

SCPH-7003 is an untested ENGLISH (?) BIOS.

And scph-1001 also runs PAL games without probs. It's basicly like having a chipped PS. Region free.

For the great majority of games, you'd probably only ever need three: 1001 (NTSC-U), 7000 (NTSC-J), and 7502 (PAL).

And even then, yeah, 1001 seems to work for most every game.

At this point, I don't think I'm going to bother with switching the BIOS before testing games from other regions, as I haven't run into any problems so far. But, if I do, I'll certainly make a note of it.

This is all based on what I noticed.
The Last Digit marks the region, 0 for Jap, 1 for USA, and 2 for Europe.

I myself find 7502 to be the most compatible. I only have used two bios files, 7502 is my first choice, and 1001 for a backup option, never needed any other, and this holds true (for me anyway), in any emu I have tried.

My SCPH-5502 bios works fine, so your one is definitely corrupt.

that explain's why my SCPH-5502 don't work then it's corrupt! oh well
