Other ROM Data
Genesis VDP Register List Locations
Knuckles' Chaotix reloads VDP registers with each game mode. At each address is a list of word corresponding to the register/value words sent to the VDP (unmodified). A word $0 ends the list.
ROM offset | Description |
---|---|
$B34 | Sega screen |
$3736 | Title screen |
$4CE6 | Level |
$5A8A | Special Stage |
Music Playlist
At address $76ED0, a null-terminated list of bytes corresponding to song numbers is given for the five normal levels and the two Isolated Island levels (see RAM address $DFF2). The World Entrance determines which song to play in code, so a code edit would be required. All other game modes play a song directly.
