well, i downloaded every NDS rom, (WOW LOTS) and I tested them on ideas. (each of them)
none worked perfectly but people tend to think that running a little bit of polarium and running the intro to metroid prime hunters is all it could do,
THAT IS WRONG
Asphalt Urban GT (forgot which version) played the intro, slowly, just like metroid prime hunters
Madagascar worked GREAT (a little slow) all the way up until you were about to play the game
Meteos E3 Demo worked okay at the starter screen but everything was wierd at the gameplay
Mr Driller Drill Spirits worked BEAUTIFULLY (speeds good) until it got to gameplay
Lots of other ones loaded up the nintendo logo and stopped, (or maybe they were going REEAAALLLYYY slow)
This is great news that i discovered, iDeaS is really close to hitting the perfect emulation
I will add screenshots later, i have to go somewhee
