I am trying to run old PS1 games, but they are all in .bin, which acording to the wiki can be emulated with PCSX ReARMed . I don’t know how to install it (as a core) since I am using an x86 computer. Thanks for help.
Use mednafen-psx instead. It handles bin/cue just fine. Just be careful with the BIOS, as that core is extremely picky. If you load the core (but not a game) and then go to information > core information, it will list the BIOS files it expects and tell you whether it finds them or not. The names are case-sensitive, btw.
