yeah i know that u need a load and expansion cart i was just pointing out that there is an emu since people always say there isn'tFrom the looks of it... I'm partially right.
While it IS in fact an emulator and not a loader, it's actually being emulated on the iPlayer and not the NDS.
It also looks like it has two limitations:
1). Needs an iPlayer flash card.
2). Needs the DSi hardware.
And the only reason it can do that is because the iPlayer has an onboard ARM9 CPU @200MHz and an onboard DSP CPU @400MHz.
