I realized I made some mistakes when backing up certain games. Thankfully I found out now, and not 5 or more years when it might be near impossible to make or get new backups of older games.
Some games, like Twisted Metal, Twisted Metal 2, Fable (1996) have audio tracks that go away if you convert it to ISO. I'm pretty sure that if the CUE file has anything talking about tracks or audio in it at all, then that means leave it as a CUE/BIN, correct? Some CUE/BINs I've found don't have the track or audio text, so I figured they didn't need to be CUE/BIN.
A lot of backups on this site seem to have CCD/IMG/SUB (sometimes a CUE is in there, not sure why), and I'm not sure if it's okay or not to convert those to ISO. I think the SUB is for DRM information? Kind of like MDS/MDF, where MDS contains DRM information. I've found that it's okay to convert CCD/IMG/SUB and MDS/MDF to ISO with no issues other than some DRM might require you use No-CD or a Mini Image, which is okay for me because Mini Image takes up less space and sometimes No-CDs don't work or have issues.
Speaking of space, this is why I try to convert to ISO when I can. ISO compress the best for me when using WinRAR or 7-Zip, so it's important for me to know what is safe to convert to ISO, so I can archive as many games as possible, and not ruin them when converting to ISO.
Any answers or tips are appreciated, and thank you for your time.
