How to hack coins (Advanced knowledge)

[ryanhn717]

Hi guys, I am recently working on hacking a single game, but it seems the game use very special encrytion similar to Xor, but far complex. I had some basic Xor knowledge like X4..X24 (address offset), or encrytion value near the Xor key. etc. But this time really confused me a lot. it seems using  multi Xor ?  maybe this ?

A ^ B = a
C ^ D = b
a ^ b = 5000(real value e.g.)

(After I find the value, change it directly, the game crash. Then I change the nearby value together, it works but detected as Cheat.  I tried to find the Xor key nearby, but failed.)

Here a short video shows you how it looks, Hope someone can help me out.  Really appreciate!!!
