Hi, new speedrunner here, and decided to try speedrunning undertale as my first game. I have trouble doing the jetpack skip and I'm not sure what I'm doing wrong. I do the text overflow (text storage) or whatever I should call it, pretty easily which lets me skip the first part (mettaton cooking) but I always see my character just waiting at the jetpack area as the screen scrolls towards my character. I've tried many things but still am not sure what I'm doing wrong.

I've been following xandertje10's guides and its been extremely helpful. Sorry if this was a stupid question. Just didn't know where else to ask.

You need to make sure to reopen the punchcard after getting the overflow. For some reason you have to open the punchcard and close it while still having the its too dark textbox to be able to skip the second part.

Exactly what cookie said: do the overflow, close the punch card, open and close the punch card again without closing the text box. Then walk into the cooking show cutscene, mash away the text saying its too dark, walk into the jetpack trigger, mash away the rest, leave the room.

Feel free to ask us any other questions, but it would be a lot easier and faster to do it in our discord. So make sure to join that!

After getting the overflow, close the punch card, open menu, ITEM, Punch Card, Use, close punch card before the dialogue box from the overflow finishes (or you'll close that as well).

Also don't overmash on the second punch card even though you have be fast, because then you'll interact with the wall again and you'll have to start all over. I prefer to add in a small arrow tap Down after closing the 1st punch card so I can then mash Z/Enter as quickly as I can to open and close the 2nd punch card.

So my keypresses would be: Ctrl Enter Enter EnterZ Z Down Ctrl Enter Enter Enter Enter

Thanks for all your help :), I think i pretty much got it down now!!
