Unlike modern single-file downloads, original PlayStation games are disc-based and often come in multiple parts. Understanding these formats is the first step:
Originally used for playing PS1 games on the PSP, these files are convenient because they can merge multi-disc games (like Final Fantasy VII ) into a single file. 2. Organizing for Playability
For multi-disc games, you can create a simple .m3u text file that lists each disc's filename. Loading the .m3u in your emulator allows for seamless disc-swapping without cluttering your game list.
