The new model GBA SP comes in a redesigned clamshell case with a screen that flips up (just like a lot of mobile phones). Further finally Nintendo has added the so much missing Frontlit. Last but not least the GBA SP comes with a rechargeable lithium-ion battery as standard, providing the unit with 10 hours of battery life with the light on and 18 hours of play with it off.   This stylish new unit measures 82 x 84.6 x 24.3mm, weights 143g only and plays back all usual Game Boy Advance and of course also standard Game Boy (Color) games.
