Pretty good port, but incomplete nonetheless
Seeing as it's missing 6 characters (those being Zangief, Felecia, Ibuki, Tessa, Dan and Akuma), high jumping (Down>>Up), unblockable flash attacks, a buttload of music tracks and then some, it just doesn't feel like Super Gem Fighter in all its awe and glory.
But still, the fighting system is pretty much there. (Although isn't Sakura's 3rd super supposed to be a grab-type attack?)
