Unown mode works! This is a mode based on
Unown Mode from Pokemon GSC.
When you see a new Unown form, it gets added to Unown Mode.
In order to trigger Unown Mode, you must have seen Unown at least once. To trigger it, you can call
pb_unownmode_scene()
Note: Unown Mode hasn't been added to the Pokedex. This means you MUST call that script to see it. That way you can use it in a lot of different ways.
