PSX BIOS NOT WORKING

mitu

Please add more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
You're supposed to copy the BIOS files in the \\retropie\bios folder, not in the ROM or config folders.

I don't find this text in your first post, that's why I mentioned about it.

Can you show a screenshot of your BIOS folder ? I suppose that 'through internet' means using File Shares, so the folder should be visible from your PC.

The emulator should also produce a log file where any error messages are shown - it's in /dev/shm/runcommand.log, but you'll need to use WinSCP to get it. Try to get this log file and post it here in the forums, surrounded by code tags (```).

The extension is wrong, because Linux is case sensitive, so it should be SCPH1001.BIN, not SCPH1001.bin.

also got the program that you said and nothing in the SHM folder opened with WINSCP

Make sure you search for the file immediately after starting the emulator and don't reboot the system - the file is erased when you reboot.

Changed it to all caps went to the system opened the command line and searched that after that i went to see if theres the bios and still no bios.. i dont know what im doing wrong i think i have to delete the retropie and reinstall it maybe i did something wrong with the settings or who knows cause im new to the retropie thing.

I had same issue. I had to put the file in the BIOS folder and inside the ~/roms/psx folder too

Panikos1

Tried that too but didnt work i guess ill try it again with diffrent some other bios us-eu

If you're using pcsx_rearmed as emulator, then the only BIOS is recognises is the SCHP1001.BIN one; the Libretro core (lr-pcsx-rearmed) can use other BIOS files and it doesn't care about upper/lower case. However, the standalone emulator (pcsx_rearmed) is the one recommended for a Pi0/1, since the Libretro core is too slow for those models.
So which one are you using ? How are you searching for the log file ?

Panikos1

using the SCHP1001.BIN i have it in the BIOS folder but it doesen't get recognized when im opening the games it tells me No bios for playstation and if i hold a button a go to the menu theres no other to select and there is the default one lr-pcsx-rearmed

Without a log file (/dev/shm/runcommand.log) it's hard to say why it's not working - having the right BIOS file in the BIOS folder it's enough.
Maybe you've changed the settings in RetroArch and it doesn't know where to find the BIOS ?

Panikos1

Can you give me a simple step by step on how to check that on the retro arch.
Tbh i touched the retroarch but i dont remember with having to do with bios.
Thanks a lot for your help!

mitu

RetroArch searches the BIOS in the System directory. Check where this directory is set by looking into the Settings -> Directory menu. First entry should be the System/BIOS - check what value it's set there.

Panikos1

The value is correct at home/pi/retropie/bios i remember it correct
nothing wrong here

Panikos1

Hmmm im getting to a point that i think Reinstalling retropie will maybe help
what do you think about reinstalling ?
