      RetroPie issues with using any emulator that needs bios. I have tried updating and have been trying to get NEO-GEO, PSX, etc to work. All which need their own bios. I have downloaded all the correct copies of the bios. I insert the BIOS in to the BIOS directory on the Pi; as well as copy the bios to the root of it's corresponding ROMS folder. All other consoles work great, SNES, Genesis, etc. Thanks!

          For the PS1 bios, the file must be named exactly SCPH1001.BIN, you renamed it and added a PSX - prefix. For the Neogeo part, please add more information - which emulator are you using ? Also add the info requested in https://retropie.org.uk/forum/topic/3/read-this-first, it's useful to diagnose your problem.

            @Colinhb89 are you sure you have the correct neo geo romset for the emulator you are trying to use?

              eg "metalslug2.zip"

              hmm, i don't think any of the neogeo emulators are expecting that romname. fblapha wants mslug2.zip, as i think they all will. looks like a fairly fundamental romset issue.

              also your PSX bios name is wrong.

                It'll handle the bios names in lower or upper case and a variety of different versions but they must be named in the scphXXXX.bin or SCPHXXXX.BINformat. I've been using scph7502.bin. I don't believe there's much of a difference, if any, I've just had this handy for years.

                There's no guessing to this. Renaming files is your problem here.
                For some examples of bios names: https://github.com/RetroPie/RetroPie-Setup/wiki/Playstation-1

                Get the romset version for the emulator you want to use and DON'T rename anything. https://github.com/RetroPie/RetroPie-Setup/wiki/Arcade
