Playing games on this calculator wasn’t actually possible until it was hacked late February of 2010.
The hack (Called Ndless) basically allows you to run custom C programs, including GBC4Nspire which is a Gameboy and Gameboy Color emulator. This allows you to play any games (known as ROMs). Here is a nice video of some games running on it. I’ll make a tutorial on how to do it yourself sometime during the next week. All music was added afterwards, seeing as the calculator does not have speakers. Well done to the developers of Ndless and GBC4Ndless!
