This is only called on game reset. |

| $009C1F | 69 bytes | Controller | Mario's movement data on Title Screen. Format: xx yy xx yy xx yy [...] $FF The XXs is the value to store to $15, except that the Select flag (#$20) is instead used to tell if the XY flag (#$40) should be masked away from $16 (if it's set, that bit is stored to $16 unchanged; if clear, that bit is masked away. All other bits are stored to $16.) The YYs is how long to keep that value there. Setting an XX to $FF ends it. |
|
| $009C6A | 1 byte | ASM | Change to 80 to open save game menu without pressing a button or Title Screen Playing. | |
