Like the title say, why don't implement a trainer feature.
I remember time of Xbox Original and Evo-X dashboard.
That dash had a trainer system completely internal. All trainers was a little file (coded) that had TitleID and Timestamp of the *.XBE file (for the right identification of the game) and a little ASM code that was the "code" of trainer.
For the creation of that file, was needed good knowledge of ASM and a little program called "Easy EvoX Trainer Maker".
Maybe in Xbox360 it's possible the same thing. And maybe it's possible to add a little menu that pop when press the home button and where it's possible to choice what code activate or de-activate. Like in FSD with latest plugin enabled where was possible to access to a file manager or return to FSD if you are in game.
I don't know if all of this is possible. Maybe i don't know what i'm talking about just because i'm ignorant in this matter
Just a suggestion. Great work anyway!
