Revert PlayStation LZ77 Compression

[Eldinen]

I am using your amazing tool with this script:

http://aluigi.altervista.org/bms/ps_lz77.bms

The file :
https://drive.google.com/open?id=0B2552 ... kg4TlQxSmM

The script works perfectly, but, how can I revert the process? To be able to compress the file in the same Lz77 format again.

Thanks in advance!

Have you tried to use the decompressed file as-is with the original name and checking if the game loads it?
Because that lz77 seems a sort of gzip-like file, a single compressed file with a "LZ77" magic.

Worst case scenario you have to create a fake recompressor on your own (compressed size bigger than the uncompressed one)

I added the file I am trying to compress

I havent tried if the game works with the decompressed file, in anycase, I guess I should put some fake header I guess.
Anyway, I will try.

A fake header is not enough mainly because it's not that easy, if you know C feel free to check the function ps_lz77_decompress in the src\unz.c source code of quickbms

Yes, i know C, but it isnot my main programming language hehe.

But, if you know how decompress the file with your algorithm, cant you revert the process?
