There should be an "encounters.txt" in the game folder. That lists the available Pokemon for your version of the game.
This game only has a battle tower.
unzip just like the main game folder. copy and paste contents of patch into game folder and hit overwrite all.
Yes. Game Corner prize. You...
You don't. v6 only goes that far.
Okay so if the backtrace is correct the issue is likely the loading of the "size" property added by the Essentials Deluxe plugin. When that feature was added to said plugin, it required the start of a new save so I can only assume your save file is old enough...
I'd be fine with it if I get to see something unique and interesting done with the story. However, it might take some getting used to, as sometimes games change a legendary's personality completely and that usually messes with my perception of said legendary for a while.
Using deluxe battle I set up a wild battle with Galarian Moltres. I manually chose three moves for it by setting up an array like in the instructions, but the fourth move slot was automatically filled with heat wave, which is from Kantonian Moltres' moveset.
Please elaborate. The window appears then disappears? Or does the game window just never appear at all? Or does an error message appear before it closes? Do you make it to the title screen at least?

Note: Yes, that is a Patreon page, however you DO NOT have to pay to download JoiPlay!
Note 2: The only version I've confirmed to work with this game is JoiPlay 1.20.015 and RPG Maker Plugin...
