I’m confused how Playstation ROMs work. Other systems just have the one file but Playstation seems to have several and in different formats. I’ve tried a .bin file and that worked though RetroArch can’t see the game despite scanning the directory so I have to load content instead.
A different ROM I downloaded has four files, .ccd, .cue, .img and .sub. What are all these? .img appears to be the main file as it’s the biggest. That ROM loaded and does appear in my games list but doesn’t have box art.
I’ve also had a ROM the same as above but the .img file was named .img.ecm. Why? Should I remove the .ecm suffix at the end? This ROM doesn’t load at all. RetroArch says it just fails to load and that’s from load content again because it won’t show up in my games list. The difference between this one and the other one with the four files is the one that works is a European PAL version, the one that doesn’t work is North American NTSC version, in fact none of the NTSC ROMs work.
Then there’s .ISO. I have all my original Playstation discs. Should I convert them all to .ISO? Will those work in RetroArch? Would music tracks still work?
I’m new to RetroArch. Previously I’ve used ePSXe to load Playstation games direct from the CD-ROM but the games run too fast.
What core should I be using? I tried PCSX ReARMed but that doesn’t seem to work at all, in fact when Load Content that core doesn’t even come up as an option so I use Beetle.
