During a Nintendo Wii security discussion, Team Twiizers revealed an undocumented processor, Nintendo's ticket scheme, and that Nintendo apparently knew the Wii was capable of DVD playback but opted to disable the functionality.
To quote: One thing that they discovered was a previously undocumented processor in Nintendo's game player. This tiny processor, dubbed "Starlet" by the team of hackers, was embedded on the Hollywood graphics chipset and was described as a "full-fledged NEC ARM system-on-a-chip."
Not even licensed Wii developers knew of the chip's existence or of its role in the Wii's security scheme. Nintendo's secrecy about the existence of the processor successfully hindered attempts to hack into the Wii until its discovery.
In hacking the Wii system, Team Twiizers also came across Nintendo's ticket scheme, which lets Nintendo authenticate whether software is allowed to run on the Wii or not. They pointed out that the tickets allowed Nintendo to save costs and distribute their downloadable software through conventional networks, since it prevented users from simply copying their virtual console titles and playing them on another console.
Another thing they found was that these authorization tickets had an unused time-limit functionality. This functionality may be used in Hudson's upcoming Joysound Wii karaoke software in Japan, which offers timed subscriptions to its song library instead of permanent downloads.
Since the initial discovery of these tickets, they noted that Nintendo has released patches that have done a good job in preventing the specific problem of Virtual Console piracy.
Team Twiizers also discovered that Nintendo did support DVD playback in the console, but had disabled the functionality. Thinking that leaving the functionality in was an unintentional oversight, and since their goal did not involve DVD playback, they contacted Nintendo to warn them of the issue.
However, Nintendo did not respond kindly to their attempts at communication.
