I figured, I thought I would ask though just cause it's really nice to play on my TV and run it through my capture box. I really had no idea which core it used, so asking here seemed the best option. Thank you!

Hello. I'm just getting into speedrunning and I was wondering if the rules allowed for using a console box like the Retrofreak to run the game. It's emulated and upscaled, but I can't really say much more than that. It's just my preferred way of playing though, since I don't have to run things through converters all over the place.
