How to Install psx games in retroarch? Please help

Hi guys, I wanted to install some psx roms that I have through retroarch, emulating them with the core of sony playstation beetle, however I have not managed to run, I have seen post that talk about correcting or installing the bios for psx, but not I know how to do it or where to get that document to install it, I have a version of retroarch 1.7.0, I am not sure if it is the last one or should I update it and how to do it? I’m a little lost to achieve it, could you help me?

The roms have the archives .bin and .cue but i dont know how to make it run

Check out this thread - it’s not Retroarch but a stand alone emulator though: PCSX ReARMed for GameShell
