It kinda feels like a beta, or at least a pre-release/first revision of sorts. I know of at least two other V.Fame games (Soul Falchion and Digimon Pocket, both from the multicart) that use older resources/music. In fact, Soul Falchion uses mismatching palettes for their characters, possibly because they didn't change it from Super Fighter Alpha. Meanwhile, the single cart releases in Taiwan have the new stuff in it.
