Can't get Playstation Emulator to see my BIOS file

Sinkyboy2000

I have the BIOS file for the default PlayStation which is SCPH1001.bin. I have put this in both the BIOS folder and in the ROMS/psx folder. I understand it's case sensitive, so it's saved exactly as I have said above.

I put it in those locations by copying it from my windows pc by going in to //retropie

When I start the emulator it tells me I don't have the BIOS. What am I doing wrong?

Are you using lr-pcsx-rearmed?

I had a similar problem when using pcsx-rearmed.

@Sinkyboy2000 if it really case sensitive then the .bin needs to be .BIN i have it in all caps and thats how i downloaded it.

Sinkyboy2000

Thanks both.

I originally had it in caps and then change .bin to lower case. I've tried this on lr-pcsx-rearmed and pcsx-rearmed. Neither have recognised the BIOS. I presume it's nothing to do with the way I've copied it across (remotely from a windows PC)?

@Sinkyboy2000 there's no point trying it in lower case. it is case-sensitive, but for upper case. see the documentation: https://github.com/retropie/retropie-setup/wiki/playstation-1#bios

Thanks for that. I tried it upper case first, but no dice.

@Sinkyboy2000 so i would correct the bios name. Then go into retropie settings. Then go into retropie setup. Then in there choose update retropie-setup script. Then after that finishes while you are in there reinstall lr-pcsx-rearmed and pcsx-rearmed

@edmaul69 - Thanks for that. tried it and it didn't work.

Check that the file's md5 is 924e392ed05558ffdb115408c263dccf. If not, your bios is likely bad. Other than that, double check that the file is in the right place (/home/pi/RetroPie/BIOS/SCPH1001.BIN). Also check that ownership/permissions are appropriate to read the bios file. The file should be owned by pi:pi with 644 permissions. The directory should owned by pi:pi with 755 permissions. You can change ownership with 'chown pi:pi <filename>' and change permission with 'chmod 644 <filename>'.
