>Yeah thats the system bios. I know in regular computers you cant add any type of additional programs to it
Actually, I suspect we'll be finding out that it's not the "BIOS", so to speak, but "Firmware" - Software that is written within the hardware. And Firmware can be upgrated - if it was initially designed with that in mind.
A system "BIOS", if I'm correct, is also a type of Firmware. In fact, an older computer I had actually had a BIOS upgrade come out shortly before Y2K to upgrade it so it would be Y2K Compliant.
So it's entierly feasible that NoA could release updates in the future (Via NiFi, WiFi or cartridges/cards that upgrade when they're played for the first time).
The thing that would make all of this interesting is to see what "hackers" could do to your system... Just think, someone is downloading what they think is an illegal ROM of Mario's latest adventure, they start up their DS and *blammo* - a $150 paper weight. And, of course, Nintendo wouldn't fix it....
