apparently the highlighted stuff has a stupid syntax error.

How do you highlight stuff? I would like to now how to do this. Thanks!

There is a select button on the keyboard (I believe it just says SEL) by the copy/paste stuff.

"INC SY -1" in the line above it may be the problem. If the intent is to decrease the value of SY by 1, then replace that with "DEC SY".

I already used inc <var> -1 and it worked, without any errors. Also, it started because I removed the endif from an if, (said there was a syntax error there too) so I think my old 3DS is dying. Either that or I need to charge it lol

Don't you need comma for INC/DEC?

yep, figured it out 5 min ago
