I figured out what Zahir wrote^^ BTW EvillyG00d!!!!
to do the x/20i you need to subtract 4 * 20 or 2 * 20 (for thumb ) from the offset
BTW
1. watch -location *0xADDRESS gives you some better info than just watch
2. instead of display/i $pc you can do x/i $pc
and it doesnt do what u said it does.... complicated to explain.... like reload for ammo, or not enough coins if u attached a watchpoint to coins, pc will display the function that gives u the alert view saying u can't buy
3. you can use c , cont , or continue
