@Shakz That did not work sadly, I used to have to do that for NES in particular, but ever since joystick selection tool, that has been fixed. Now I just wish there was a way to install that when ROMs are run from a network share - it errors out during install. But I just manually edited the SNES retroarch.cfg file.

Howdy Friend,
Nope sorry there is no way...at least with my setup. All my dreamcast games have a cue file followed by track1 track2 track3 etc.
All the other games have the exact same files so the only way to keep it from messing up is to keep everything in a separate folder.
Unless you are using...I think they are called CDI files which compress and combine the audio files....but you take a major hit on audio quality when you use them.
Just my thoughts.
