Hi everyone, i am going to buy a xbox 360 arcade, that is flashed. What i would like to know is with the arcade model can you play any back-up or real game from Viva pinata to big one like GTA4 and Mass Effect 2 ? And its on ixtreme firmware 1.6 so i think i just use a activate.iso in order for them to run yeah ? because they are wave 4 games ? Thanks please help if you can. Thank you
