[RESOLVED] PSX invalid BIOS

I just got RetroBat set up and it's running everything great except for PSX. I've put the schp1001.bin and schp5501.bin bios files inside the "RetroBat/bios" folder but it still says the schp1001.bin bios is invalid. It seems to recognize the schp5501.bin bios, but still says that the bios is missing when trying to run a game. I've used this same bios file on all my emulation set-ups and it works fine, so I know its the correct one. Any ideas what I'm doing wrong?

Hello..

But does the game launch anyway?

Please choose an avatar

Yes, it launches but with graphical issues. I did check the md5 and it matches what is in the retroarch core info, however in the "missing bios" menu within RetroBat, the md5 number is completely different and doesn't match any psx bios I can find.

I'll pick one

Try to choose another psx core.

Both Mednafen and PCSXReARMed say the bios is missing.

Try to add all of them...

Interesting... that scph1001.bin md5 looks to be from a development bios instead of a retail bios. I'll try it later tonight and see if it works. Thanks.

SOLVED! For anyone else having this issue, download the DTL-H1001.BIN bios file and rename it to scph1001.bin

Hi there - sorry to revive this thread but this is the most appropriate one i found.

I've been having issues with my PSX bios as well. I have added all the PSX bios (see list below) into the retrobat/bios folder. I also did a bios check on retrobat and nothing is missing for "playstation".

However, when I try to start a PSX game, it will crash and retrobat will say "an error occurred: the emulator exited unexpectedly".

Would be grateful if anyone could help. Thanks!

Maybe it's not related to the bios but to the game rom that is incorrect...
Or the video driver that is not compatible with your hardware

Can you start by pasting the last part of the emulatorlauncher.log file after a failed launch ?

The file is located in retrobat\emulationstation\

Sorry I am unable copy and paste the logfile directly here because I have installed retrobat on another computer without internet. But I copied the logfile into word, and have taken a picture of it in the above link.

Hope this works for you!

Your games are compresed in .7z
is not the good format.

uncompress it.

Thank you very much @tartifless and @Lorenzolamas - it works now.

The zipped folders work for my SegaGenesis games and SNES roms, so I had assumed that there was no need to unzip PSX roms too.

Sorry for the silly mistake, and thank you so much for your help.
