| 90 | Mario/Luigi horizontal position. Changing may cause problems in Name Table. |
| A2 | Mario/Luigi vetical position in levels. |
| A3-?? | Enemy Sprite positions on screen |
| BD | Current horizontal speed |
| ED | Current Form: 00-Small, 01-Super, 02-Fire, 03-Racoon, 04-Frog, 05-Bear, 06-Hammer |
| EE | Mario/Luigi Character Sprite Displayed(gets set just before display) |
| EF | Mario/Luigi status flag: 40 facing right, 00 facing left |
| 0100-01FF | CPU Stack |

| 0577 | Determines if Player is inside the Goomba Boot: 00-No, 01-Yes |
| 05EE-05F0 | Time remaining |
| 0715-0717 | current player score divided by dec10. (max F423F[dec999,999]) (There's a hard coded 0 in the score display) |
| 0736 | Mario # of Lives (max 63[dec99]) |
| 0737 | Luigi # of Lives |
