Bug: In this game, unlike the sequels, the CPU players will go after any item that spawns with reckless abandon. If there are just two level 9 CPU players on the stage, and an item spawns, they will both go for it. If they are equal or approximately equal distance from it on opposite sides, they will steadily walk towards it. Once they get within a certain distance of each other, their Level 9 defense programming kicks in, and they will shield roll past each other, and the item. Get up, and do it again, and again, and again bringing the fight to a standstill until the item fades away.
Other mistake: When you finish the classic mode, there's a credit. When you see Charles Martinet's name, it says "Martinee" instead of "Martinet."
