Changes

Released on April 5, 2009, the '''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". However the 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, and did away with backwards-compatiblity by removing Slot-2, which was used to load GBA cartridges and other gaming accesories (''i.e. Guitar Hero DS: On Tour'').
