In Reply to: Nintendo DS "edge card" posted by japen on Saturday, 7. June 2008 at 16:42 Bali Time:
Hi there, we were in Bali recently and came across these. They were in a DVD shop in Poppies 2 not far down from the Legian St end, next to or near a surf board shop, on the same side as Bali Bagus. The lady in the shop was explaining how they worked. You buy the cartridge and choose the games to put on and later down the track you can even delete those games to choose differnt ones. So they were expensive to start with but once you have the cartridge they work out very cheap.
Hope this helps....
