I agree that this is difficult, and only made more-so due to the insanely high numbers used in these trainers. If they used sensible numbers then it could just be a "get me out of this hole" tool instead of always going from "I have nothing" to "I have more resources than this game was meant to account for and now I have nothing to do" on every single trainer.
I love the work this site does, I just get terribly confused by their choices on things like that. Seems like a lower number, and just pressing it more if you want more, is the only sensible option, but that's just me. You can always add, but you can't take away what has already been added. It seems this would also keep trainers from being noticed as often, as there wouldn't be game-breaking huge numbers all over, meaning less updates and work needed by Cheat Happens. Maybe that is just the web designer in me talking...
An example for this trainer are money and bag slots. There is no middle ground, just all or nothing, which makes those features either game breaking or useless.
Again, I love the work this site does, I'll just never understand some of the choices made on specifics. Hopefully the admins will take this as constructive comments, not personal attacks. I'd hate to be banned for just stating this.
You make some interesting points. I don't know about the bag slots, but you can use CosMos to find your cash value and custom edit it to your desired amount. I used it to give myself 50 Mil units. I'm down to 30 Mil, but one of my goals is to try and farm myself back up to 50 Mil (basically grind back the "loan" I made via cheats).
