| ====== Levels ====== | ====== Levels ====== | ||
| + | Each level loads a struct of areas using function 0x800F78E4. | ||
| + | The game uses this structure to find the pointer to the current area in the main stage table. Its located at 0x800be500. | ||
| + | Note: when used to select levels its bytes, but its stored in ram as words. | ||
| + | <code C> | ||
| + | struct Level | ||
| + | { | ||
| + | /*0X0*/ u8 World; | ||
| + | /*0X1*/ u8 Level; | ||
| + | /*0X2*/ u8 Area; | ||
| + | /*0X3*/ u8 NodeNum; | ||
| + | }; | ||
| + | </code> | ||
| + | The pointer to the main stage table is gotten by using this formula: | ||
| + | |||
| + | WORLD*48+LEVEL*4 loaded from offset 0x800d1f98(table of ptrs) | ||
| + | |||
| + | Each Area is then just an additional 0x24 from that level pointer. | ||

| - | ===== Area Setup Blocks ===== | ||
| - | Area setup blocks define the camera settings, collisions, and object placements for areas. The high level structure is as follows (in order): | + | ===== Level List Locations ===== |
| + | These are the locations of each level in RAM and ROM. Each area in these levels goes in sequential order. Meaning to get to Level 1-1 Area 2 you need to add 0x24 to 0x800d01a4. | ||
