Notes
Working
update 20091223 from David Haywood: it's not very interesting without the dump of the P8749H, it only differs from the original Bubble Bobble by 1 byte (which could be bad, the game has an internal checksum routine which happens during gameplay, and the game will randomly crash if any mods are made to the rom and the checksum routine isn't patched)
