I've checked these so far, all of them worked fine for me.
1. Grand Theft Auto: Chinatown Wars (great game, beat about 60% of storyline missions and just last week I lost both the save files for no good reason
)
2. Professor Layton and the Curious Village
3. The Legend of Zelda: Phantom Hourglass (sucks to the limits)
4. Akagawa Jiro Mystery Tsuki (lol @ all Japanese, can't understand shit)
5. New Super Mario Bros. (I apologise for that)
Today I got my hands over a 165 NDS Roms DVD, will check 'em as soon as I could.
