Specific instructions for games with 2 discs?

is there anything I have to do differently for PS1 games that have 2 discs (MGS, FF7, etc) I tried to run it the same way I do for other ps1 roms but I only get a black screen

The easiest way of doing it is making an m3u file (it’s just a text file with the cue sheets listed one per line with the file extension *.m3u) and loading that instead of the individual cue files. You can then use the disc control options to increment the disc index, cycle the tray, etc.

how do I do that, also would I be able to fix the problem if I zipped the bin and cue files together, it’s probably a stupid question but I fiqured that would be a good idea but wanted to know ahead of time

Once you load some content, go back into the ‘quick menu’ and the disc options should be in there.
