Well, I never had any problems with the files, but recently I got Fpse on my phone and it says to always use the .cue file from a .bin/.cue. Whenever I use epsxe I always choose the .bin as I thought its the biggest file from the two, but I never knew that some of the music is lost when using the .bin file. So heres my question, out of all the other files which one do you select?
.bin/.cue
.img/.cue
etc.
