Jam Sessions 2?

I happen to be able to play Jam Sessions 2 in No$GBA, but whenever I try to change the chords the screens turns black and I cannot go further without knowing where everything is on the screen.

How do I bypass this problem so that I may play the game at least a little bit?

EDIT: I was going to put a more meaningful title but I forgot the words I wanted to use and just went "fk it" after I couldn't remember.

 

Have you used No$Zoomer?

 

Yeah, but it still does it.

EDIT: Funny... Turns out that if you wait like 10 minutes it'll come up.

 

Where'd you download it?

 

I can't remember, but I looked all over for it.

How do I make it run smoother? It runs more choppy than Jam Sessions 1 does on an emulator.
