Thank you for the link! I will look into doing that since I know a lot of people are eager to try it on the AP. Though, I do have a lot of custom engine mods so it might be a bit tricky.
I looked into migration into 3.0 and for the same reason of custom engine mods, I'm pretty weary of it. The custom hitbox size would be a gamechanger (literally), but since I've designed this with the 16 pixel in mind, I honestly don't think I'd them.
In regards to the GBC exclusive content, you can see in my reply to N8Master that I've got a custom screen setup for that! It was a lot of fun making that one :)
