"Finally, as Raf explained in the DS forum, we're pulling out of the supposed "race" to tunnel the DS - at least for now. Under current conditions, we don't feel like we're making sufficient progress right now to keep people hanging on, and I genuinely wish anybody else attempting the same thing the best of luck. If things change, you will be the first to know, but for now, we're pulling back from it all. At this point, I'd like to extend a huge thanks to soul2soul and l3laze for pushing us as far as we went, and to Tim for his invaluable contribution with the Sweex stick work."
XLink Kai - the tunnelling company working to tunnel the DS has given up. This is a sad and surprising announcement. Wha' happen'!? (Fred Willard voice) "Not enough progress being made, everyone scratching their heads, time will be spent on other areas of development (and new avenues)." I thought things were going so good. We'd have it in a few weeks. Metroid tunneled. Smooth play. 100ms ping. What specific technical issues fluffed them up? Well, apparently the speculation goes that 1. the connection wouldn't hold 2. they came across hardware issues. 3. something was too well encrypted or otherwise secured.
I can't offer you solice now. No one can.
...But, TheDaddy assures that "All relevant research will be made available to those who want to take this and work on it on their own" - provided you're capable. And Soul2Soul says: "yes it ran, but on a expenisive router and the programming would take ages. Blame Nintendo, they couldn't use a normal protocol. Everyone wants DS online... but no."
Forum poster J_Man61 said it best: "Nintendo is probably sitting next to some wireless device that will let us play online. just sitting laughing and petting it"
