Guy's i think its because you guys yell to much "help" instead of really trying.
Ok follow these steps:
1. TSR: Normal
2. Find out what game region your Xbox backup is, then go to the Settings menu and select the right region. For example - If the backup is an PAL and the trainer is NTSC and you turn all the stuff on(Money, infinite health) and then you go select the game and then you find out that it doesn't work, And you say "Hey TRAINERS ARE FUCKING crapzuiziet!".
You can find the region in the Video section in the video section there is something called Game Region instead of "default" switch it to what ever region the trainer is!(TIP: It is in the bottom).
I have done this and it has always worked.
* Remember (Put all your trainers in c:/trainer and only the .etm file. - I also put the .asm file in, but this is not necessary it is just the code).
