When I play the game with friends and family the skill is in using to the best of our ability the naturally perceived rules of the game.
Using your controller to input bits of data directly into the memory using a bug in the software is completely different sport.
There's usually a "no major glitches" category, which shows more of the main game. In SMW this is called either 96 exits or 11 exits. Those are actually the default categories that are most heavily run from what it looks like.
For Super Mario World, for example, records are tracked for with/without glitches, pure-human play versus tool-assisted, how much of the game is played through (since even without glitches there are ways to complete the game without playing all levels), etc.
The current record for playing all 96 levels of the game is, according to speedrun.com, 1:22:21.310. Here's the video of it:
This is just the extreme form of the fastest way to complete the game, using the (broken) logic of the game itself.
Exactly the same situation as comparing play at home with kids to any elite world record setting play in the same game... "This world cup is not at all how I play at home ..."
