#include <nitro/mi.h>void MI_UncompressLZ8( const void* srcp, void* destp );void MI_UncompressLZ16( const void* srcp, void* destp );| srcp | Source address where the LZ77 compressed data is stored. |

None.
Decompresses LZ77 compressed data and writes the data to the specified region of memory. The source address must be aligned to a 4-byte boundary.
The MI_UncompressLZ8 function writes in 8-bit units. On NITRO, you cannot decompress directly to VRAM. On TWL, this is possible, but it is quite slow.
The MI_UncompressLZ16 function writes in 16-bit units. On both NITRO and TWL, you can also decompress directly to VRAM. However, the process is slower compared to normal memory.
For compressed data, allow for a 2-byte lead when searching for matching strings.
Decompresses data compressed in LZ77 or LZ77 extended format using ntrcomp tool or an MI_CompressLZ* function.
Processing takes place only on the CPU, without the use of a system call or DMA.
