Hi!

1) Usually we buy from local shops - Sg Wang, Imbi, Djinn, etc. Sometimes we buy used games from other LYNers. Sometimes we buy them from Play-Asia.com too.

2) Around RM 120-150 for a new game. Sometimes more, sometimes less.

3) Yes, you can buy pirated DS games. They'll be a little cheaper than the originals and you need to flash your DS before being able to play them.

Hope this helps!
