I recently started converting tracks to support Re-Volt 1.2. I convert the bitmaps to 32bit and add an alpha channel and repack custom files to the /custom/ folder (if there are any). I recommend checking the following link periodically as there are many more to come.
Among those (might not be all of them):
- Jailhouse Rock by Human (jailhouse12.zip)
- Sakura by Human (sakura12.zip)
- Venice by Gabor (venice12.zip)
- Rooftops (stock track, roof12.zip)
- Re-Ville by Spaceman (re-ville12.zip)
