Thought we could post our tips and tricks whilst using FMRTE
Things like the superman cheat, I'll start:
You can make a player constantly play well, or a youngster develop quicker by using the superman cheat solely on them and freezing them. With "Allow attributes to increase" selected in the freezer settings in fmrte
Open their page, edit their fitness and match exercise to 12000 or whatever, save it, freeze the player and save it again
And there you go. Go to your fmrte settings > Freezer settings and click on allow attributes to increase.
