savepos OFFSET
math ZSIZE -= OFFSET
math SIZE = ZSIZE

Sorry for the extreme dig, but the file's actually laid out like this (per the demo Stargaze Framework SDK I found):

Code: Select all

struct pvrlzo {
char lzodata[];
uint signature = 0x7d620abd;
uint decompressed_length;
};

So the compressed data length is (length of file)-8, and the actual size is from the last 4 bytes. Signature in struct above should be reversed to little-endian when stored in file.
