| callbacks | Address of the MIReadStreamCallbacks socket. |
There is no return value for SVC_UncompressRL8().
If the return value for SVC_UncompressRL16FromDevice() is greater than 0, it is the decompressed size. If it is less than 0, it is an error.
This function decompresses run length compressed data and writes the data to the specified region of memory. Match the source address src to the 4-byte boundary. If the size of the compressed data is not a multiple of 4, make adjustments by paring the size back using 0.
The SVC_UncompressRL8() function can be written in 8-bit units. You cannot decompress directly to VRAM().
The SVC_UncompressRL16FromDevice() function can be written in 16-bit units. Compressed data on devices that are not memory mapped can be decompressed directly without using a temporary buffer.
