I dont think you're able to find any shop selling original games in Penang.
My friends used to order them from a shop in 1-Stop but that shop is closed now.

It's hard to survive if you're planning to sell only originals in Penang. I propose you set up an online shop so you can cater to more customers.

Even the pirated sellers are having a hard time now as most are getting new games off BT.
