Because i had to shop around a bit when looking for this, i thought i would upload it here so that people can get the right one.
This works perfectly(tested) with the the Codex and Fitgirl releases that are out at the moment (2 December 2017.) (Game version 1.21)
Please allow in your antivirus as this WILL give you a false positive.
1) Run the game and when you have reached the menu alt+tab out and run the trainer as administrator. You should now hear a "Ding" everytime you activate an option on the trainer. You can also hit the laptop screen icon (lower right next to the mute) and use the trainer from in-game using the number bar above the letters of the keyboard.
2) Run the trainer. Hit the music mute button (lower right). Run the game. Once you have selected to continue or start a game, and you are in game, start turning on options
*note: This WILL give you a false positive on most anti-virus software. Dont use whie the game is loading, ensure you are in-game when in use. This could corrupt your save if not used properly. Use at your own risk!
