Now, I have read something about the "BIOS" files, and insert them for more compatibility, I have seen that there are several types.ġ) Do I have to manually add all the BIOS files for pcsx reamerd?Ģ) If so, should I add ALL the ".bins" or just some?ģ) In which directory should I add the ".bin" files exactly?Ĥ) Should I rename the BIOS ".bin" files to uppercase and lowercase or does it make a difference? This can be done in the menu at Settings > Drivers > Video Driver. I am quite familiar with retroarch, I am aware of having to download the "pcsx rearmed" core and then import my psx roms, and then everything is ok. /rebates/&252fscph5501bin-download. The scph7003.bin BIOS image is the same as scph5501.bin, but will need. I already have retroarch installed, I use it mainly with core snes but as explained in the title I would like to emulate psx games. Hi guys, I see several videos on youtube of people playing playstation 1 games on switch via Retroarch using pcsx rearmed as the core.
