Hi everyone,

I’m a music producer currently working on a large Sims-themed album, and my goal is to release it alongside a mod that adds all of the tracks into the game.

I attempted this a few years ago without success. I’ve done extensive searching since then, but the only guide I consistently come across is Flyby's guide here. Unfortunately, despite multiple attempts to follow it closely, I haven’t been able to get it working.

Are there any alternative approaches, tools, or more up-to-date guides that I may be missing or is that guide my only option?

Have you taken a look at this thread? It's still a beta version but seems to get the job done for adding new audio files to the game. As for adding your songs to the already existing rotation of BGM, rather than replacing, I'm not 100% sure. But that program should hopefully be a good start. The creator of the tool appears to still be responsive to questions as well.
