Well unfortunately I don't know of any good way to record a GBA screen other than the gameboy player or an emulator

use an emulator

I don't know if I've seen that before, ledge grabbing usually works fine. (I'm noah642 on discord if you want to ask questions there)

Biggest tip I would give right off the bat is, collect the invincibility crystals and use them during the boss fights

@Shadowbrine1 Hey there, glad to see a new runner of this game after so long, let me know if you have any questions
