Several items (Rock Spear, Turbo Boots, Magic Anchor, ...) interact with the map and thereby open new paths.
Relevant addresses are listed in the following table:
Name | EN | JP | G0 |
---|---|---|---|
Currents Control Script | 91BD9E | 91B6F7 | 97E1AD |
Currents Table | 91BE17 | 91B770 | 97E226 |
Diving Bubbles Script | 91BC51 | 91B5AA | 97E060 |
Diving Bubbles Table | 91BD86 | 91B6DF | 97E195 |
Currents (Magic Anchor)
The Currents Control Script operates the currents on any map it is paced on. It checks the Currents Table, which is shared for all maps, to decide if and where to apply currents. Currents can be avoided if the player has the Magic Anchor (item 0x49) in his inventory, in which case the script does nothing.
Currents Table
Offset | Length | Description |
---|---|---|
0 | 2 | Map ID (the current entry only applies to that map) |
2 | 2 | region left |
4 | 2 | region top |
6 | 2 | region right |
8 | 2 | region bottom |
10 | 2 | forced X-movement |
12 | 2 | forced Y-movement |
(14 bytes per entry, terminated by Map ID = FFFF)
Diving Bubbles (Air Herb)
Diving Bubbles are added to maps as sprites with the following declaration:
01 <x> <y> <id> 91B5AA 82F0D2 (JP) or 01 <x> <y> <id> 91BC51 82F05F (EN)
The id is used as index in the Diving Bubbles Table, which controls the target of each tunnel:
Offset | Size | Description |
---|---|---|
0 | 2 | x |
2 | 2 | y |
(4 bytes per entry)
