The Dexnav is now updated for Pokémon Essentials v19!
To install, simply add the 2 scripts IN ORDER above Main, and copy the graphics folder to your game folder.
This currently allows for 12 different encounters per map, but can be updated to accommodate up to 21. Seeing as most maps do not have more than 12 encounters anyway, this should suffice. If you want to expand, just expand the section of the script with Lengths referenced and change it to whatever you wish as long as it is no higher than 21. The UI that comes with this does not support more than 21 encounters per screen.
Also within the script, you will see area listing Pokémon names. Those are to address regional variants that have different egg moves than their base forms, so change those up as you wish based on what form number you want to have it update to.
