Hey :S

I got the function for resources, but it has a check which would make the game freeze..

This is the code:

I tried the following:

CMP W0, W19 to CMP W0, W0 -> resulted to saying i dont have enough money (which I do)

CMP W0, W19 to CMP W19, W19 -> resulted in the freeze

NOP'ed the CMP -> resulted in a freeze.

How I know the sub_x function is money?

I did MOV X0, X23 RET on the sub_x function & it gave me unlimited money.

But, when buying something it restarted the game so I assume this has some check too.

Anyways, how do I deal the CMP in this function?

Thankyou in advance!
