you have a modded Xbox? If so then you want trainers and not cheat codes, there are no cheat codes for Xbox with AR Max like with PS2 they have game saves (powersaves) instead which are not at all the same. I bought AR Max too thinking it would be like it was for PS2 but it is a real waste of money. The most you will be able to do with it is start you game with certain things unlocked that would normally be locked because you loaded a 100% complete game save. If you have a modded xbox let me know and i will link you to some trainers sites and tell you what to do to get them on the Xbox. I have the trainer files for Halo and Halo2 and so many others. codejunkies.com is where you get game saves that are not already loaded on the AR Max. then you transfer them to the AR Max memory card with the USB cable they have and then put the memory card in your Xbox controller, the use the MS Dashboard to browse the memory card and copy the save to your Xbox so you can load it from within the game
