Scarlet Legacy compression

looks like the header is xored with the alphabit or something like ABCDEFGHIJKLMNOPQRSTUVWXYZ
but thats not needed for these files just run offzip on them and you get the decompressed files.

[finale00]

So I wrote a bms script for it
It replaces the original compressed file with the new one (with -o option), but right now it leaves the uncompressed size as the first 4 bytes for some reason. How can I modify this script so that will delete the leftover?

The uncompressed size was at the end, so maybe that's why it is included in the output? offzip also did the same.

Code: Select all

#scarlet legacy decompressor

goto 0x40
get name FILENAME
get filesize asize
math filesize -= 4
get csize long
savepos offset
goto filesize
get size long
clog name offset csize size

[chrrox]

save it to a memory file first.
then just get the memory file size - 4 and log the file starting from the offset 4.



get name FILENAME
string name +.dec
goto -4
get size long
goto 0x40
get zsize long
clog MEMORY_FILE 0x44 zsize size
get size asize MEMORY_FILE
math size - 4
log name 4 size MEMORY_FILE

how to get models out of the pkt files

[finale00]

The pkt files are just compressed textures.
How do you figure pkt contains models?
