MxOf is a data section that appears early in most SI files. It appears to be an index of the byte offsets in the file indicating the starting positions of each file stream.


NOTE: This information is incomplete and requires more research and information.

Bytes Offset Description
"MxOf" 0 4-byte data identifier
Chunk Size 4 4-byte integer specifying the size of this chunk minus the first 8 bytes
Total List Size? 8 4-bytes whose purpose may be the total number of indices/byte offsets, but is not entirely clear yet
Offsets 12 The rest of the data are continuous 4-byte integers indicating the byte offsets where MxSt streams start.
