Most likely a trainer was not possible to be made.
I made one, so it is. I used Cheat engine and got infinite health working, a money cheat of add and subtract money, and a change weight an freeze weight, working. I have no way to share it though. The health cheat is easy to do in Cosmos, but have to do it each time unless you know how to find pointers. It is a floating point number of 100.
