I recently started making music hacks, I've been submitting them to the BrawlVault but I forgot to make a topic here. Anyway here's what I've made BRSTMs of, You can also request songs to me here If you want.
Redial from Bomberman Hero
Happy Cat Factory from Chip 'n Dale Rescue Rangers
Japon from F-Zero X Expansion Kit
Title Theme from Tin Star
I work on BRSTMs everyday so this place will probably get updated often. Maybe.
