Cheat Engine is a program that enables you to edit a program's RAM while it's running. You can use this program to edit the RAM in Sonic Adventure 2, and the below cheat table file contains the addresses so you don't need to enter them manually. It also contains some additional values relating to Chao, as well as a few tweaks to enable or fix certain things.
Note: All values are signed, unless noted otherwise.
