Recently, I’ve downloaded a copy of Final Fantasy VII (all three discs). Discs 1 and 2 work fine, and are in ISO format, but I move on to Disc 3, and it is broken into three different files; .CCD, .IMG and .SUB. The emulator I use (pSX) says it supports running those types of files, but whenever I try, it won’t load.
How am I supposed to run it? And I don’t want to download any unnecessary programs.
