$0000 1 byte Temp Memory Holds ()
$0001 1 byte Temp Memory Holds ()
$0002 1 byte Temp Memory Holds (Hitbox)
$0008 2 byte Temp Memory Holds (DoorPointer??)
$000a 2 byte Temp Memory Holds (PlayerLocation??)
$0011 1 byte Temp Memory Holds (WhipHitboxHight)

$0018 1 byte Screen RomeLoader Mode 4=Loade 5=Black(07=debug)
$001a 1 byte RNG Random line. This is incremented by 1 every step. It's used for randomization purposes and results in a linear pattern whereby a function X will return the same result X[n] steps later and X[n+1] will always be the same when n is a linear function. Of course, making n a non-linear function will yield results closer to what one would consider "random".
$001d 1 byte Temp Temporary Used Memory Holds (set to 01 Pause) (Set When on Stairs ??)
$001f 2 byte RNG Random bump. While $001B is used most for random actions, this will vary things up a bit. This gets incremented and then $001B is added to it. This is done repeatedly between iterations. Basically, in GM terms, thisi is run between the last Draw event and the first Begin Step event.
