Cartridge Beware! Nintendo Announces Two Different Cartridge Types
The upcoming Nintendo DSi is considered to be an upgrade from the DS Lite. People who do not upgrade, however, need to be careful of the new games they buy.
At the GDC 2009 Nintendo announced two seperate cartridge styles, one of the DSi only, "DSI Cards", and the other for all Nintendo DS, "DSi Enhanced Cards", which will have extra features for the DSi.
DS owners heed the warning, watch the cartridges you buy in the future.
