I actually implemented the Lori copter fix some while ago (it'll be in the next update), but thanks anyway Gry. Speaking of Lori fixes, I figured out how to fix Lori's fur color and to make her clothes color customizable. The only problem is that some colors in Lori's sprites should stay purple and yellow, like her airboard and her explosion effect. Ideally, Lori's fur and clothes in the sprites in Anims.j2a would be changed to green and red respectively, and JJ2+ would handle the color correction so that Lori's colors displayed yellow and purple by default. I'm just not sure if it's worth the effort, and others might prefer the current behavior anyway.

By the way, Lori's clothes color will be editable by setting the value that used to change the color of the tip of Lori's gun. This means the tip of Lori's gun will stay red, but the rest of the gun can still be different colors. I had to keep either the gun tip or Lori's eyes fixed at one color, and I chose the former.
