    Hi everyone!

    I made a lot of search about my issue but I could not find any good response. My question is easy. In raspberry, where is the BIOSs path for PSX where I can copy my BIOS files? Currently the ‘native’ BIOS is very weak and it is misleading that I start a PSX game and it says in yellow ‘No BIOS found’.

    Thank you!

    The native bios seems to be lack of quality, some of the psx games have graphical glitches, wrong colors etc and low fps (dunno if bios version fault tough)

    Hi!

    I got it! I have psx games working! I think I had two different issues:

    First of all, You can choose a system directory editing this file:

    /etc/retroarch.cfg

    I choosed this one:

    /home/pi/RetroPie/BIOS

    And I put here my pcsx1001.bin file. Im trying to do the same with neogeo.bin for MAME…

    Next I saw that the error (The screen with the errors is ultra fast, but making a video with the phone will work) was that my libreto.so must be renamed to pcsx_rearmed_libreto.so, and thats all!!

    I hope this will help someone.

    Motorhead, I think you have the right idea about the systemdirectory, but I’m not sure about renaming the libretro.so file. Mine still looks for libretro.so exclusively. Also, did you mean retro instead of reto? Just curious, still trying to get this to work 110%.

    Great work here! If you have found a working solution it would be great if you could add these information to https://github.com/retropie/RetroPie-Setup/wiki/PCSX-Core-Playstation-1.

    Hi! Sorry, it was a mistake, it’s libretro.so you’re right. The error given from Pcsx_rearmed was in a 1.8, and that solved the issue. Few days ago I reinstalled a fresh 1.9.1 image and there was no signal from this error… there is no need to rename libretro.so now.

    Okay, awesome, thanks for helping to clear that up. Also, I got mine to work with a specified bios on the most recent version. Here’s a write-up:

    Create the directory to store BIOS files:

    /home/pi/RetroPie/BIOS

    Make sure you copy your bios files into that directory with no capitalization in any part of the name or file extension.

    Next, edit the file:

    /RetroPie/configs/psx/retroarch.cfg

    and add the line:

    system_directory = /home/pi/RetroPie/BIOS

    Thank should do it. If anything doesn’t work with that solution, holler down below.

    Logré de que ya no aparezca el mensaje de “no BIOS found, bugs expected”, pero no noto alguna mejoría, así que no estoy seguro de que sirva, pero lo que yo hice fue poner una Bios en la ruta /opt/retropie/emulatorcores/pcsx_rearmed/ con el nombre “scph1001.bin” y edité el retroarch.cfg que está en /opt/retropie/config/all/ y hay una línea que dice “system_config =” y agregué la dirección de dónde estaba la bios. Si, uso la versión 2.3. También necesito ayuda. Con Dino Crisis ocurre un error visual en el menú de objetos y eso, y también en el menú de PlayStation. Se ven muchas líneas negras en la pantalla, dificultando la lectura, si alguien me puede ayudar con esto se lo agradecería mucho.

    Figured it out, in newest retropie, they go into

    /home/pi/RetroPie/emulatorcores

    Not in the subfolders of that folder.

    So in the above folder you should have all your SCPH????.bin files.

    Has anyone successfully run PSX games with the new Retropie 2.4.1 beta image? Mine always crash regardless of which BIOS file I use. All PSX game start up just fine but crash within a minute.

    I have – although I found compatibility to be somewhat poor. I did find some games that worked though. Hopefully compatibility will improve with updates but Crash_Bandicoot worked for example.

    I had the same problem, all of my psx games were working just fine in 2.3 but once I upgraded to 2.4.2 they crash halfway through- I have the proper BIOS and everything. Hopefully someone comes up with a solution for this bug.
