The mosters movements in Bubble Bobble are totally wrong. Only Raine emulates the monsters movments accurately. The best way to see how messed up the monsters movments are in MAME, is by comparing level 80 on MAME with Raine. Use the cheat to get to level 80, and you will see what I mean. The Bubble Bobble emulation in MAME is very bad compared to Raine's.(posted 8345 days ago)And Rainbow Islands Extra uses the Rainbow Island C-Chip simulation which makes the monsters positions and movments totally wrong. RIE does work in .58 but its badly bugged, so its not a case of finding the correcy rom set, the emulation needs fixing.
