Update 2018-8-19:

Updated the post to match the official player page rules. Previously, it was a reconstruction of NStride's post from 2011 that contained many broken image links. This has rules for more tracks written out, but introduces no breaking changes to the leaderboard.

Yes that is a intented shortcut and thus allowed

Missing the Sherbet Land no respawn ultra, N64 Bowser's Castle ultra, Koopa Cape ultra, and GBA Shy Guy Beach ultra even though it doesn't save time in a 3 lap run anyways.

Charlocharlie, When you said no using an IOS is banned, Does that mean i can't use CTGP?

ISOs (disc images) are banned. CTGP requires a disc to work anyway, so there isn't a concern for that.

If IOS were banned, the Wii wouldn't even run :)

This was very helpful, thanks! :D

Updated the rules and diagrams for the new skips discovered in the recent months
