I don't get how to get it a video would help PLS

If you own the steam version, it's as easy as opting in to the 'beta' under the game's properties. In our "Guides" section, it goes into more detail.

Thank you for the help ;)

also is there any tutorial on how to do any% with teqxt storage?

I don't believe there's a fully fledged tutorial on beating any%, but in this AGDQ 2015 youtube mirror, FieryBlizzard explains the number of times to press flip to increment the game qualifier, so that, in addition to the many runs on the leaderboards, should be more than enough to learn the route.

He begins running Any% glitched at 16:27

How does incrementing work?
