How were you supposed to know to press UP to enter the door?

It's in the manual.

Save state, push a random button, reload if it doesn't work, push a different button, reload, continue in this fashion.

By trying everyone buttons until you get it.

I legitimately got stuck here when I first played it as a kid.

I asked my older cousin next to me who was a fucking legit genius tier nerd, he couldnt figure it out. He then got his legit genius level dad to try and he took a minute to finally figure it out

I should not, I think one of the problems was you had to stand like directly in the middle, or it was like UP + A button or some shit.

I dunno, but I still remember that day 20 something years later

You either read the manual to learn the basic controls, or you press any of the 8 buttons on the controller.
