I'm not sure if that's really compressed.

I found a reference to "ZLFW" (the magic at offset 0x10) in the double_dragon_neon.bms script and in that case there is no compression involved.
Also most of the samples files like "bf" and "d7" don't look compressed because their 16bit or 32bit structs are intact.

wfLZ is the compression algorithm used by WayForward's internal console/pc engine (http://www.wayforward.com).

https://github.com/ShaneYCG/wflz

You can find algorithm here.

Need to build arguments to decompress and compress.
because the github just have a example.

but all algorithm is in there.

maybe implement in quickbms in future?

here is for some games of wayfoward

Ah, that wflz, yeah that compression is already available in quickbms as: comtype wflz

It's just that I didn't have any script in my collection using it

ok, done:
http://aluigi.org/bms/zlfw.bms

I don't know if it's better to dump the decompressed data in separate files or in one.
The header of ZLFW makes me think that it's just one file so that's how I programmed the script.

You are a life saver! after decompressing these files,i'll conver it to texture.

Are you pretend to compress to insert this file in the game?

I think you did right programing in just one file.
The compressor works fine in your descompressed data.
only the header, that shoulded to maintain, because when compress, the header is lost.

Spamning topics from colleagues, it will not bring answers for your problem,on the contrary, it will only bring dislike from other users.

Hijacking topics of other users is really a shame moreover after I already deleted his previous post few minutes ago.
