I submitted a run 8 days ago, and it hasn't been verified. I don't really mind if you mods are on vacation or something, but can you find some time to verify my run? Thx.

What emulators are allowed for this game?

Good luck on the PC building and happy playing.

Hi! I'm not the most knowledgeable when it comes to this specifically, but I'll try my best to answer. 

I actually do run the game on original hardware (a GBA SP specifically), and because of that I just use my phone camera pointed at the screen. It's not preferable, and the quality is subpar, but it gets the job done.

Alternatively, a majority of people here run the game on an emulator, which with recording software like OBS, makes it relatively easy to capture. 

If that's not your thing, there's also the Super Game Boy, Super Game Boy 2, and Game Boy Player, all of which allow you to play GB games on your SNES/Gamecube. For those I believe you'll need a capture card? (That specifically I don't know much about, others here would be better at answering that.)

Anyways, that's the extent of what I know. Hope this helps, and good luck with things!
