How to add audio tracks to a disc image?

Question

ISO

There is an image with the old game. In the game itself, soundtracks are played, which in the original version of the game are recorded on disk in the form of tracks, i.e. audio cd. There is a separate image of these tracks. The question is how to add them to the image with the game?

Answer 1

You need an image in cue format, not iso - everything is cubed there as it should.
