Surprise~

We did something.

Now everyone can stop asking about this.

How to add music:

1. The music you want to add must be OGG format. Not just an .ogg extension. If it crashes because you renamed an .mp3 to an .ogg , that's not our problem.
2. Create a new directory custom_bgm in your DDLC/ directory.
3. Drop the oggs into that directory.
4. Launch game.

Technical

• Files are checked for access as well as extension. Appropriate files are added to music_choices in the initMusicChoices function.
• I've also added some checking in init to clear persistent.current_track if its filepath does not resolve to an actual file. This will prevent crashes if the last played music track is removed prior to next launch.

Will you continue to add default music? I think this is neat and all, but I still adore 80s Doki Doki, and I never would've come across that otherwise. Or the most recent track that was added

[ThePotatoGuy]

Yes, we'll continue to add music that works with MAS.
