Final Fantasy IV Text glitch

I am having trouble with my Final Fantasy IV rom. I am running it on No$GBA 2.6a, and the text keeps sticking or stacking to the point that I can't read anything. Is there any way to fix this?I have No$WTT and PMP, but I'm not sure how they are supposed to fix the glitch, or if I have them set up right. Can anyone provide a suggestion?

........My..my...where the past thread about this problem....It seems I can't find it..Oh well...Here's how to fixed it....
- Download the no$zoomer 2.3.0.2
- Extract it to the same folder with No$gba...
- Run No$zoomer(locate no$gba when asked)
and...It's fixed...But, other problem will arise...the reduction of the emulation speeds...
- Just go to No$gba settings
- Change the "Emulation Speed, LCD Refresh" to "Realtime*2" or other...For more information go to Common Issue Thread. :)Have fun!!
