1) dunno much about NDS but i do have a NDSL for sell though. looking for around rm400 offer. pm me if interested
2) not sure as well. but i dun think there's recon NDS in the market. the reason being it is not as hot as PSP. correct me if im wrong.
3) one of the main games are pokemon. i think the latest now is black/white. some games i used to play are FFTA2, mario kart
4) the OS and specs for NDSL is lousier than PSP
