*.GMA \?
*.GMM \?
*.GMO \model?

I want to converter GMO to obj, please.

Everything is encrypted

I dont think its encrypted i think the extractor he used is wrong
if you look at the original bin file there are readable strings in the file sections
so just need to get what type of compression they used.

Quickbms script

getdstring MAGIC 0x10
get FILES long
goto 0x20
comtype BPE
for i = 0 < files
getdstring NAME 0x20
putarray 0 i NAME
next i
savepos baseoff
set tmp files
math tmp * 0x18
math baseoff + tmp
for i = 0 < files
get NID long
get ONE long
get size long
get zsize long
get COMP long
get offset long
math offset + baseoff
getarray NAME 0 NID
if COMP == 1
clog name offset zsize size
else
log name offset size
endif
next i

How did you figure out the compression type?

@OP, I'm guessing you deleted the file because all you needed was the decryption script?

[chrrox]

its super easy with luigi's compscan and bms script.
all you need is the raw file part with the uncompressed size and it will try every compression quickbms knows for you.
then you just look at the output files to see what one decompressed correctly.
i chose a dds file because i know what that should look like.
