Can you add an option for using the GBP as its official hardware and not an emulator? also, its much easier to record

Is there a list of accepted/banned emulators?

I use the Mupen64Plus-Next core on RetroArch usually, want to know if thats fine or if I should use Project64

When the misc categories say that NG+ files are allowed, does that just mean that you can have already beaten the levels and just have to show beating them again? Or is there some way to reset your save data without resetting your cars that I'm unaware of?

For the "collect all plasmids" is it just the level 1 plasmids?

When should i start timing? when i hit play or when it loads in?
