Knights in the nightmare sound issues

Alright I've dl the US version of Knights in the nightmare and everything seems to work fine except the sound.
It's choppy/laggy, basicly it just doesn't sound good, I'd appreciate it very much if i could get some help.I'm using NO$GBA 2.6a with the NO$Zoomer.
Here's my emulation setup if that would help http://i25.tinypic.com/3586gci.jpg .Once again this would be very appreciated.

Have you tried not using No$zoomer with it? It's been a while since I've played this game with no$gba, but I seem to remember it working ok with just 2.6aAnd have you messed with the Sound quality in the Emulation Setup? Reduce it a bit to see if it plays better.

Yeah i have, the screen starts to flicker and the sound is still horrible.
I've also tried changing the sound desired sample rate and that didn't help either.
Could you maybe recommend some other emulator instead? maybe that would be a lot easier.

You could try other ones, like iDeaS, or DeSmuME

Alright I tried iDeaS and that didn't work.
DeSmuME has perfect sound but the screen flickers and to click any of the boxes i have to click on the 2nd screen even tho they are on the first or vice versa.

Wait, how'd you fix it?

There's a topic on Ngemu with a list of addons, one specializing in better sound.
