Aluigi, how would I go about reinjecting edited files? When i try i get this error:


Error: script invalid for reimporting, it uses MEMORY_FILEs

Last script line before the error or that produced the error:
73 clog NAME 0 ZSIZE SIZE MEMORY_FILE

Unfortunately reimporting is not possible just because it's used a MEMORY_FILE for the compressed files, the reason is explained in the script: "this operation is necessary because the algorithm expects a sort of 32bit at the beginning of the data set to zero but the files of the game don't have it".
Even if I find a way to ignore that 32bit field then you will have a wrong invalid compressed file in any case because lzrw1 will add that field in the compressed data.

No problems for the non-compressed files.
