Hi,

 

I am here again. Really want to learn IDA Game Hacking but still nothing is succesfull.

 

This is the code: 

; ShopViewController - (void)setEstoqueDeRetry:(int)

; void __cdecl -[ShopViewController setEstoqueDeRetry:](struct ShopViewController *self, SEL, int)
__ShopViewController_setEstoqueDeRetry__
MOV             R1, #(_OBJC_IVAR_$_ShopViewController.estoqueDeRetry - 0x50244) ; int estoqueDeRetry;
ADD             R1, PC  ; int estoqueDeRetry;
LDR             R1, [R1] ; int estoqueDeRetry;
STR             R2, [R0,R1]
BX              LR

I changed it to:

; ShopViewController - (void)setEstoqueDeRetry:(int)

; void __cdecl -[ShopViewController setEstoqueDeRetry:](struct ShopViewController *self, SEL, int)
__ShopViewController_setEstoqueDeRetry__
MOV             R1, #(_OBJC_IVAR_$_ShopViewController.estoqueDeRetry - 0x50244) ; int estoqueDeRetry;
ADD             R1, PC  ; int estoqueDeRetry;
LDR             R7, [R1] ; int estoqueDeRetry;
STR             R7, [R0,R1]
BX              LR

it does act like a NOP to me now ://

 

any help..?

Try a game that is not possible with flex :p

When I try that I don't even know what I have to search. I am trying to learn iDA Hacking....

The point of hacking with IDA is that it works with games Flex can't keep up with. You learn nothing when you can see everything of the app and what everything does

Yes.. but don't I need to understand the basics of changing functions before doing it on games which are 874887 times harder?
