[size=14]To execute arbitrary code to access data on GBA Flashcarts a PassMe device was needed. The problem was that it was big and sticked out like SuperPass, and soon there was newer firmwareÃ¢â‚¬â„¢s on the Nintendo DS that didnÃ¢â‚¬â„¢t let PassMe devices work. Later, A PassMe device was created that could be programmed to work with the newer firmwareÃ¢â‚¬â„¢s, but many people didnÃ¢â‚¬â„¢t know how to set it up.
PassMe and PassMe2 devices soon evolved into NoPass devices such as SuperKey and PassCard, that are exactly the same size as a normal DS card and allow code to be executed from all the Slot-2 Flashcarts.
What does it do? Well this allows SuperKey to work on any Nintendo DS, without any programming, it doesnÃ¢â‚¬â„¢t stick out of the Nintendo DS, and features like Ã¢â‚¬Å“SleepModeÃ¢â‚¬
