I propose to create two separate categories for the console and for the emulator. Because the emulator loads data faster than the console, this time can be saved for such a speedrun. For example: Start timer on emulator loading time before stage 1 - 4.5 sec., on console - ~6 seconds.

I agree!

I have a better idea. How about we just go by the in game timer instead of using Livesplit. That way loads can no longer have any advantage.
