Looks like Bubble Bobble Revolution for the DS was released with a serious bug: the boss for level 30 never appears. I’ve noticed a similar bug in the wifi multiplayer mode, a lot of the multiplayer levels wouldn’t spawn any enemies. Good job codemasters! I guess I’ll have to wait 8 – 10 weeks for a replacement cartridge, though I haven’t managed to get past the first boss yet anyway, the new age version of the game is hard! At least there’s the classic version to play in the meantime.
