iQue NetCard

From RGDWiki

The iQue NetCard was a cancelled project by iQue and BroadOn to enable network and USB connectivity for the Game Boy Advance in China. It consisted of a special GBA cartridge containing an IOP-like processor along with USB connectivity, to allow for digital game distribution and online play.

The NetCard was also to feature onboard memory and an ES-like DRM system for preventing game piracy.

The Wii's system infrastructure was heavily based on that of the NetCard.

Details about the NetCard were exposed in the Zammis Clark Breach.
