I decided to rip Golden Time: Vivid Memories sprites but when I tried to convert the .gtx they didn't work. I opened them in a hex editor and they all start with SL01 and it looks like its a type of encryption rather than a container.

Here are some sample files: https://drive.google.com/open?id=0ByT2bSlsZ3XGYzlfeUw0YVF6M3M

Would there be any way to decrypt them?

it's not an encryption it's just a lzo1x compression

just made this simple script and worked for the files you've uploaded but don't know if it will work for the rest of the files :).

Code:
comtype lzo1x
goto 0x4
get SIZE long
get ZSIZE long
get NAME FILENAME
string NAME p= "extracted/%s" NAME
clog NAME 0xc ZSIZE SIZE

Thank's that works.
Yeah I meant to say compression not encryption. I was really tired when I wrote that.

it seems neosis cant handle some of those vita gxt, but scarlet/gxt convert can extract some but a few can't still be exported.

according to MrAdults it should be able to handle all of them and you should
upload any that won't work so he might update his plugin if he feels up to it,
but i was mainly referring to the samples provided in this thread when i posted. :)

I'm using scarlet since the normal GXTConverter seems to give me a jumbled up mess when I convert it to png. Though I'm about to try the .gtx noesis plugin.
