Unlike the original version of the 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 GBW1 memory location, which now contains code instead of the expected data, producing an arbitrary noise.
This fix restores the intended wave patterns and works on the original Japanese or translated ROMs.
