Two of the music tracks in StarTropics are slightly broken, the island map music, and one of the ending tunes. This patch fixes them both.

I’ve also created a fully labelled disassembly, and complete description of the StarTropics music format. For anyone looking to hack new music into StarTropics, this will be a good guide.

Some emulators, notably Nestopia, do not support modifications to the StarTropics ROM due to a conflation of the MMC3 and MMC6 mappers as iNES mapper 4. If the emulator has to use a CRC check to select MMC6, it may have problems running the patched ROM (e.g. audio will be silent, and name registration will fail). Newer emulators may instead support or require updated ROM headers for Startropics. To fix this, you can try one of these two patches (but not both):

• Mapper Fix - iNES 2 header for newer emulators.
• MMC3 - Converts MMC6 to MMC3, for older emulators.
