I am a bit disappointed that there aren't leaderboards for each level. I think that having those would increase the number of players who speedrun the game.

It should be listed under the downloads section of the Project64 Website.

Yes. That is the only one that is allowed. But you have to use version 1.6.

Can someone please give me an answer on whether or not we can have single-cup emu runs now? There are many more players than there were 1 year ago.

Would it possible for reconsideration on this issue? There are well over a hundred All Cups (No Skips) players now, can we please have Single Cups Emu now?
