@todo
- Daisu Kiss: sets up 0x00257e28 as set variable in a 2p game after beating specific stages, and causes a game breaking sticky sprite.
It actually also sets up something that looks like non-sprite sub-commands in the same area (example is for character select), I'm inclined to think upper bits are actually used for something else:
00010005
00000006
000e0002
002e0080
- Sexy Parodius: sets up p1 as 2 at start of stage 1. Related to missing snow?
