zlib doesn't have this.

Now I see the pattern, both lz4 and zstd are developed by same author. Well, at least his code is nicely organized and easy to learn.

OMG I kill you man, thats great! How come I did not know.. Time to do my games all over again .
EDIT: Well actually, thinking of it it may not be enough with lz4/zstd. I dont know how you coded it but in this case for example, default library would read block structure wrong even if compression match because of mentioned crc position which is part of the block, unless your tool is skipping it and can focus only on game data.
Still, it gave me an idea that one perhaps doesnt need to repack whole game archives with quickbms anymore, because depending on how your ztool works, maybe all I need is to modify library as I did here and ztool could function again. That would be great and would made ztool universal, then all you do is compile all lz4 versions and recycle them forever. But I would like to know more in detail how your tool work/read data exactly to understand, though its probably your secret so I am not going to ask.
