The only gym puzzles that come to mind are LT Surge's and Blaine's puzzle in their respective gyms.
- To remove the "electrical switch puzzle" from Vermillion's gym, go to the "events" tab in Advance Map, and delete all script boxes that are on top of trash cans.
- To make the path walkable, delete 2 lasers from the gate and replace them with floor tiles(in the "map" tab), go to "movement permissions" tab and make all red 1's turn into purple C's. (where the gate was).

If you want only to make the gym leader inside the gym and not other trainers, go to the "events" tab in Advance Map, click on the trainer you want to delete and click "delete event" button.

To remove Cinnabar Island's gym puzzle:
- First you can delete the green script tile outside the gym (this ask the player for the key from the mansion)
- Delete all orange scripts from the machines (inside the gym)
- Unblock the path by placing different blocks where the gates are, and change the movement permission of them from 1 to 0
