you can see what it is doing in the source code of quickbms.
I think I looked at this a long time ago and its doing some kind of encryption thing.

I've seen the source.All decompression function is in asm byte codes.
all function is a byte array.

Thanks, I tested it and you are right. COMP_MSF is lzma without header.
Thanks everybody.

Interesting. Maybe I can finally finish the BMS for LzmaPack with that compression type.

In the upcoming version of quickbms you will have the "lzma_0" comtype which does the same of msf.
Additionally I have set the dictionary size to the default 16Mb in msf.
