Why you deleted the name of the game from your post?

This format is an encrypted version of JX3 Online for which I have already made even 2 scripts.
The encryption in this case is 0x62 for the whole data but I don't know how the 0x20 bytes header is encrypted. The header is necessary only to know where the information start.

The following are some of the games that use this PACK format:

• Tru?ng Ki?m http://truongkiem.com
• KiemThe
• wjx2
• njx
• jxonline3
• ...

log MEMORY_FILE 0 0x20
encryption "" ""
math SIGN = 0x4b434150
math SIGN ^ 0x62626262
putvarchr MEMORY_FILE 0 SIGN long
get NAME basename
get EXT extension
string NAME   "_decrypt."
string NAME   EXT
filexor 0x62
