//walls on no triangle grounded 80255b9c
//walls on invis wall grounded 80255c44
//251708 writes new values for speed and rotation
//8026b5f4

//80256b24 returns 2 for invis walls and 0 if its fine?
    //802560ac stores 2 on sü+0x18 which gets returned above, modfy this?
    //8025634c decides that v0 is dead
//80380e8c seems to move mario, somehow resets his pos if hes above a ceiling
//802563d8 actually moves mario

//80256278 needs to be changed to branch if its a false alarm

.headersize 0x80245000

//(make ceilings push mario outwards)
.org 0x802562a0
jal second             //adds RA by AC if no ceiling available
