Disgaea DS rom help

Hi i know emulation no longer does NDS Roms but i was wondering if anyone with the Disgaea DS ROM and no$gba emulator can help me with my situation, everytime i play disgaea ds there tend to be black lines across the screen, usually 3 on both screens and it can get annoying during the game, i was wondering if anyone knows how to fix this issues, do i have to switch emulators? or is there a download that will work for me.I'm running a windows 7 64 bit gateway laptop, but i only have issues with this game (even on other computers)As i have played the game a bit, i find it very addicting and want to really get into it but the lines across the screen keep me away from fully getting into it.

I'm afraid that problem aren't fixable yet on No$gba(even with No$Zoomer+EXTRA settings).Or if you want, use DeSmuMe.

ok, thanks for the help i dont really care what emulator use as long as i can play the game without any issues.
