I recommend PJ64 1.7.0.50b23 if you can find it for best stability

My suggestions:

Mweep% (there's more competition on this category than most here) 9:15.920 by ZGSpeedruns -

Glitchless Max% Child 2:29:56 by Makai -

Glitchless Max% Adult 2:46:35 by Makai -

Edit: oh and the classic short race category "Deku Tree no B1 Skip"

It would be cool if run types were a subcategory (separated) instead of all being in one leaderboard.

Can't you use sub-categories within the ILs?? Take a look at SM64 individual stars for example

Yeah this would be way better.
