Recommended PC specs for No$GBA

I would like to ask what would be the minimum and recommended PC specs for the No$GBA
because I have the ff:
256mb Ram
40GB HDD
64MB Video Card
Sound Card
Pentium 4.1ghz processorthe first time i used the emu... it was like emulating only around 60% (w/ sound) and 70%-90% (w/o sound) and the frame rate is is like 5-10fps?
upon getting NGZoomer however my game play experience was close to that of using a real NDS:
100% emulation with 30fps.... i was really happy that time... though upon using it again
the eumalation was 100% but the frame rate dropped down to 7-9fps >.<

those specs are way too low. No$GBA needs all it can get and then some.

Agree with Loonylion, upgrades your PC to gain differences.
