I'm organizing my game library, I have two big categories: Original ISOs, and Games that are ready to play. My problem is in the folder with the games ready to play, they are patched versions so I don't need the CD in the drive, and I love them, because they're compact, and I can just put them on a flash drive, and copy them to my HD old computer and start playing.

But the problem is that I don't have the music playing. I would like to be able to use MP3 files with the original music in the same folder as the game's executable. I remember doing this on windows in the past (I would really appreciate it if anyone knows the name of the software that made this possible), but I wanted it for ms-dos too! I don't want to have to use CUE images or CD emulation, as I like to use the original hard drives on my machines, and images use a lot of space.
