By far the worst port of Super Monkey Ball, and yet... there's something deeply fascinating about it. It's impressive that Realism managed to get such a competent port running on the GBA at all, let alone with minigames and multiplayer included.

The minigames fare better here since they don't require direct movement input, but otherwise there's little reason to go for this when SMB1 and 2 emulate so well on just about any modern portable device of your choice.
