'PACKED' files
Some of the game files are RLE-compressed, these do begin with a PACKED string.
Algorithm:
- read
PACKEDstring - read decompressed length (UINT32LE)
- read checksum (UINT32LE)
- while
decompressed bytes<decompressed length- read a byte
flag- if it is less than
128, replicate the next bytedata,flagtimes and update the checksum with+= data * flag - else, read
flag - 128bytes and for each byte read, update the checksum with+= byte value
- if it is less than
- read a byte
- check that the computed sum matches the one in header
