The whole file is just XORed with 0x40. Though files are also compressed with some kind of LZ algo, as it being a mobile game it's hard to try to reverse it.

Some of the files you sent can be opened immediately in UABEA.
But some of them, as mentioned above, are encrypted with XOR 0x40.
Decrypt them first and then edit the beginning of the file in HEX Editor.
Now you can open and edit in UABEA😀.

Try this:
 

get FILE_NAME filename
string FILE_NAME += ".decrypted"
get FILE_SIZE asize
filexor 0x40
log FILE_NAME 0 FILE_SIZE

HI,ikskoks I tested it and couldn't output the file

I assume you use "reimport.bat", but instead you should use this script for standard extraction with "quickbms.exe".
