Static Storage
The static memory storage is 322 entries big and located at 0x142A760C0 (v1.07).
The entries have a max content size of 32 bytes.
Due to this restriction the memory de/allocation in this storage is way faster than in the dynamic storage.
Dynamic Storage
The dynamic storage is allocated with the function at 0x140361A40 (v1.07).
Two HLib entries will be added, one at the start and one at the end of the allocated memory.
After the first HLib entry a new fREe entry will be added and looks like this.
This entry has the previous entry pointer set to the first HLib entry and the next entry pointer set to the HLib entry at the end.
Free Storage
To free storage the function 0x14049CDD0 (v1.07) is used.
Allocate Storage
To allocate storage the function 0x14049CB40 (v1.07) is used.
