pUnity - Unity game file precompressor

[elit]

I always thought Unity files are not compressed because I could read within them in plain text. That said, if its lz4 it mean hell to keep up and maintain, as you know we both have our fair experience and opinions about anything coming from Yann Collet - especially lz4 .

That said, why not just update ztool which already have infrastructure, lz4 support, is stable and can do stdio?

Razor cant unpdate ztool, becase he deleted the source code. pzlib too.
He has to start from scratch.

many engines use custom headers and if you try to decomp a version below the original one you will get crc error !!

Yes but that would go for ztool as well. I was thinking long time already about it, one solution could be to have set of dll's and call them depending on input parameters, then also regarding block structure this could be controlled by input params as well, for example:

ztool:dll3.1:crc1:crcu:bhd = use dll version 3.1, block checksum on(blocks contain checksum), checksum precede block(checksum is at the beginning of block), block header is located at the end of block(down). In the end most of games streams are about blocks with or without metadata. It wont cover everything but I think its a good start. Also in case of no block metadata one could specify precise parameters, like in case of FitGirl's XCOM2 WotCH for oodle which is precisely: codec 8 level 4 block 2. And so on, just some ideas.

Oh my, is this really true? Such a loss, sigh...
