I'm in the middle of testing a new any% route, got to uka bones without prison and it turns out you can skip the gates that crash the game if you get close! Doing this will save ~10 minutes first try. You only get one try to get flying, so saving before entering the portals is going to be another stopping point. Thanks to this, you also get flying during wind cycles so you can skip them, fuck yeah.

You can still crash the game if you get too close!

I got this checkpoint in front of the trigger by accident (you approach it from the portal of course). This is the way I found most consistent to get it with:

1. From the portal fall in the hols directly to the right.
2. Boost and hold the left stick downward for 2 steps.
3. Boost and hold the left stick to the left into water.

Combining this with the desert skip will make the alternate route (which doesn't go to desert at all) faster.

Also, I just found a way to utilize the only place where you can get a cutscene (+flying) in desert during uka bones. Teleport to desert, enter the lowest cave, get to the spinner that opens the gate, have a second player with a roller and get flying afterr 10 dots go by on the spinner. You only get one try, so saving before entering the portal is another stopping point.

This one saves 2 minutes from the new route.

With all these new skips, I think sub 1 on PS2 is possible B) (if you get all 5 flights first try)

Update: Sub 1 is possible if you don't save at 2 flights, load max twice and even when you don't get the last flight.
