| Address | Leangth | Type | Description |
|---|---|---|---|
| $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??) |

| $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. |
