This is the 1.0 release of Rockman World 2 Music Improvement V3. This is arguably the definitive way to play the monochrome version of this game, aiming to surpass the previous two music improvement hacks available on RHDN.
Unlike those two hacks, this hack throws out the original sound data and completely reimplements new sound data, featuring all new arrangements and takes of the original soundtrack, bringing it more up to speed with the other 4 games in the Gameboy series, as well as redoing sound effects to also sound more up to par.
It should be noted that this hack was solely made for the Japanese version, but is likely compatible with the USA and EU versions due to the small amount of changes between regions, but this has not been tested, nor has it been tested for compatibility with other hacks, such as Roll-Chan World 2.
