Hello! 
A trainer for both of these games already exist:
- LEGO Batman: Legacy of the Dark Knight Cheats and Trainer for Steam
- Moonlight Peaks Cheats and Trainer for Steam
If you would like the trainer available on another platform, you can request it from within the Wand desktop software itself. See: Game, Mods & Trainer Requests | Wand Help Center.
Have a great week!
