Changes

Released on April 5, 2009, the '''[[wikipedia:Nintendo DSi|Nintendo DSi]]''' added new lighting effects, an inner and outer 0.3 megapixel digital cameras, 16MB of RAM (compared to the previous 4MB of RAM), a faster ARM9 CPU clocked at 133 MHz, and offered downloadable titles called "DSiWare". It cost {{Inflation|USD|169.99|2009}} at launch and later dropped to {{Inflation|USD|149.99|2010}}. The system, however, was region-locked, meaning that DSi exclusives from different regions couldn't be used and the system language couldn't be changed. It also did away with backwards-compatiblity by removing Slot-2 which was used to load GBA cartridges and other gaming accessories (''i.e. Guitar Hero: On Tour'').
