| - | Always follows 0x12 command. Used near end of level layout. | + | |

| + | * Frees data in pool allocated from level script | ||
| + | * Cleanups level related stuff (level objects, pointers, etc) | ||
| + | * Cleanups geometry layout data | ||
| + | * Cleanups all 8 area structs | ||

| - | ==== 1E: ?? ==== | + | ==== 1E: Allocate Level Data From Pool ==== |
| - | Command used near the end of level layout. Maybe builds level collision? | + | |
| + | Allocates data from the pool and reset a couple variables | ||
| ''1E 04 00 00'' | ''1E 04 00 00'' | ||
| + | |||
| + | * Reallocates memory for the geometry layout node system. | ||
| + | * Allocates 0xDAC0 bytes and stores pointer to 0x8038EE98. Not sure what this is, but it is related to collision. | ||
| + | * Allocates memory for collision data. Vanilla SM64 allocates enough space for only 2,300 collision triangles. Newer versions of Skelux's SM64 editor allocate enough space for 32,767 triangles. | ||
| + | * Sets halfword at address 0x8036125C to 0. (0x8036125C seems to be just a flag that is set when Mario enters into area #2 of any level) | ||
| + | * Sets byte at address 0x803613FE to 0. (0x803613FE seems to be a read-only byte that tells you how many red coins Mario has collected so far) | ||
