So with the introduction of speedrun challenge mode in patch 1.3 will that be used for any% or will it be is own separate category?

With them releasing the games on steam under an "official emulator" does that mean that if I were submit a time I would say SMS(emu) or or Sega Genesis(emu) or what exactly?

Is there a category I'm able to run with the steam version which is Sega Mega Drive and Genesis Classics?
