Check out my blog's "Random Modifications" section for the Trainer Download Link!
To enable, just run the trainer's exe file BEFORE you start up Dead Rising 2. Then, start up a fresh new Save Game slot and have fun! I had to minimize the game to windows several times before I memorized what each NumPad1-9 did, so I don't recommend minimizing the Trainer.
Also, to kill the Trainer's sound effects, click "SFX" in the top right corner.
I did not make this trainer, someone named KelSat did.
However I have tested the trainer, and it works great!
With it much fun is clearly being had!
