I don't see the need for a trainer if all it does is change numbers.
Suspicion, disposition, buildings anti-preg potions, max rooms all buildings, heal potions max, nets max, businesses can be changed by editing your savegame.
You can also set your gold by editing the savegame but not to "infinite".
Customer happiness, building cleanliness, building security change a lot so setting them every turn could be a hassle.
If you want infinite interactions and infinite town walk/arena/studio/hospital start a game called "Cheat".
This also gives you 999999 gold, 500 businesses and every item.
If people really want it I can add a cheat page to the game that will do all of this.
It would kind of take the challenge out of the game, but I guess that is the point.
