Question regerding FF IV for DS

I'm having trouble with the DS version of FF IV. Save problems and, most alarming, screen problems. Whenever I open my inventory or any kind of dialogue pops up, the words of these dialogues stick to the screen so I'm left with a jumble of words onscreen.Anybody know how to fix this?

If you are using no$gba 2.6a, try using no$zoomer. Links can be found in the Common Issues https://www.romulation.org/forum/index.php?topic=1462.0

Is there a tutorial or a manual for the no@zoomer?

All you have to do is download it (include the English.dll) and have the files in the same directory as your NO$GBA.

Well that fixes my save problems. What about the screen glitch?

Try enabling all or some of the EX0 etc. options in the Other->EXTRA tab.

Ok I'll try it.This no@zoomer isn't gonna mess up my no@gba is it?
