I was trying to decompress this,but I couldn't, they are game character render files, but apparently they are compressed

Files Cdbt.zip

I believe it that first two int32 are decompressed size and compressed size.

As above, the first two values are dec size and comp size.  It seems to use "BPE" compression in QuickBMS.  Then I can get something like this, not sure if it's 100% exact:

hi.
