A second update from me (authorized by Blind Devil) to add an option to have the sprite die immediately (just like any normal Super Mario World sprite) instead of falling to the ground and then dying after a couple of seconds. Check the ASM file for details.
Fixed squished state sprite interaction with the player, as it was possible to capespin, kill it with fireballs/kicked sprites or eat with Yoshi during this state. Batadon's palette/GFX page properties code was optimized, so now his body palette can be changed through the CFG file with no side effects (wing properties still need to be modified through the ASM file, though). Defines for tilemaps were added for more user-friendliness. Removed unnecessary code. Added screenshot, tags and SA-1 support.
