| 27 | 248 | Bill Blaster (Bullet Bill launcher)| Shooting direction: list at nybble 9: 1=Left,2=Right,0=Both | | Height: value at nybble 10. A height of 9 or more will make the Bill Blaster invisible if the 8 bottommost tiles disappear from view, but still retains collision. | | Unknown 8: value at nybble 8. Was used by Nintendo devs, somehow as a copy of Nybble 10, but is apparently never called at all, needs testing. Doesn't seem to affect spawned Bullet Bills settings. | | Unknown 11: value at nybble 11. is stored by the game for ulterior use but seems to never be called, still needs testing. Doesn't seem to affect spawned Bullet Bills settings. |
