I opted to keep Baroque on the list regardless. It's one of those ones I'm too curious about to skip out on, and I'm a sucker for older, previously un-localized games being given an official release.
The only differences that I'm aware of are that the Wii version supports 16:9 and 480p. If I recall, the Japanese release on PS2 had these features as well, but they were removed in the US and EU versions. I never have understood why companies pull that crap - SNK did the same thing with King of Fighters XI and NeoGeo Battle Coliseum :/
