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. |
