Game Boy Wars Turbo: Music Bug Fix is a strategy game in the Famicom Wars and Advance Wars series for the Game Boy. This version enhances the original game with new maps and faster AI. The Music Bug Fix addresses a continuous buzzing sound caused by incorrect waveforms in the audio. The patch repairs these issues and is compatible with other modifications, including translations.
Unlike the original game, the music of Game Boy Wars Turbo is underlaid with a continuous harsh buzzing noise. It sounds very unpleasant and makes you wonder how it ever passed quality control. The reason for this is that channel 3 is filled with incorrect waveforms. Apparently the developers forgot to adjust the pointers when they expanded the code. It still reads the wave pattern from the original Game Boy Wars 1 memory location, which now contains code instead of the expected data, producing an arbitrary noise.
This patch fixes all known wave patterns and should be compatible with any other patches, including translations.

*** Technical Notes ***
Unlike the original game, the music of GBWT is underlaid with a continuous harsh buzzing noise. It sounds very unpleasant and makes you wonder how it ever passed quality control. The reason for this is that channel 3 is filled with incorrect waveforms. Apparently the developers forgot to adjust the pointers when they expanded the code. It still reads the wave pattern from the original GBW1 memory location, which now contains code instead of the expected data, producing an arbitrary noise.
This patch fixes the two obvious waves I could identify. If there are more I have overlooked, the fix is a simple matter of adding 0x21C to the incorrect pointers.
