The GBA version of Final Fantasy V provides many great features, such as an improved translation and a smoother user interface. However, the sound quality of GBA is pretty bad. I found this fan-made hack, which makes the music sound closer to the SNES version. I haven't had much time to test the patch, but when I tried it, the music quality still wasn't as good as on SNES, and the music sounded like mono to me.
What are your opinions about the music patch? Do you like it or not? Would you rather play with the original GBA music or with the patched music?
