Also I don't recommend that adapter. I have all of them and the 2 port adapter works the best in terms of input for pj64
You have to change them manually. When I ran sm64 I used the GCN controller too and I used x and y to turn them right and left respectively. I used the c-stick for down and up. L for Mario cam. R or z for crouching and the rest is obvious. However. I used the dpad for splits. Pressing down would trigger a split. I used the program called joytokey. You can use it for save/load states too and other basic functions.
So I'm interested in running this game (not the meme category) and I was wondering, "Where's the 'Any% New Game +' Category?". I was thinking that it would be a lot faster than regular "Non-Alternate-Ending" ("Any% No Major Skips" or Any% Canon Ending" sound way better) and would be more fun. Routing would be a lot of fun as well because of all the already unlocked perks, abilities, & weapons (Wingsuit, Airdrop, Etc.) I'd like to see it added cause I'm seriously considering running it. It's an easy to learn game and has a lot of potential. Im sure sub 3 hours is possible with "Any% New Game + Canon Ending" with proper routing, RNG, Etc..
