Most people are of the opinion that if you allow Cstick then you have to allow the Underground Maze code etc etc. I personally don't like the idea of allowing the UM code but I'd pretty neutral towards allowing Cstick.
I can't see it being very popular for other people to run because of the time commitment, but if you want to make and run a new category, then by all means go for it my dude.
Late, but
A big reminder though; RTA for this game is basically irrelevant. I stress it so much, Melee has an in-game timer and this emulator vs. Wii vs. GCN nonsense is put to rest if we just use IGT as the main timing method. If I had the final say I'd make IGT the default sorting method and set it up that way, but still add some new categories so we could harbor all sorts of competition.
I wholeheartedly agree with this. There's so many possible variables that can affect RTA that (imo) it's far easier to make IGT the primary timing method instead of making all kinds of rules to regulate RTA.
I personally would like Emu/Wii categories, especially since I'm going to switch to running on Emu until I can get the stuff I need to stream/record from my CRT+gamecube.
Seeing as how this site doesn't have listings for the individual events, this is the site I use:
http://nintendodojo.com/stadium/highscores.aspx?g=2&m=8&s=0&l=0
It also includes the scored events as well.
As far as I can tell this link is more active and much more up to date than the links listed above.
