packerman333, I know what your talking about, I know a working Nintendo DS emulator and where you can get working Nintendo DS roms from:
Nintendo DS Emulator (BEST EMULATOR, but plays only 10% of roms) -> http://www.desmume.com/
Emulator Controls Z = A X = B A = Y S = X Q = L W = R ENTER= START SPACE= SELECT MOUSE= TOUCHSCREEN IF YOU ARE NOT HAPPY WITH THIS emulator GO TO http://www.ndsemulator.com/ to search for more emulators
Nintendo DS Roms -> http://nds-roms.com/ this site does have FREE ROMS but depending on the time of day it will take A LONG TIME TO LOAD BUT IT'S WORTH THE WAIT!!! (ENJOY)
ok ds fans there wont be a fully function one anytime soon because the ds hasnt been out long enough an also not all emualtors ar work at full yet so if u want a good ds emulator then youll hav to wait a few years.
