Guys, let's be realistic here. At the glacial speed at which this project has been moving, if we were to release the Wii U mode exploit, it would take 3 years before a viable, legal homebrew ecosystem existed (and by then nobody would care and we'd have had 2.75 years of piracy).
I appreciate the effort and congratulate Maxternal and co. on getting as far as they got, but getting SMP Linux running (which is still a long way off - the trickiest issues around SMP are with coherency, locking between cores, interprocessor interrupts, etc., and not just turning the other cores on) isn't going to convince us that there is enough developer interest in Wii U mode homebrew. I do encourage you to keep going if you're interested in learning (and I'm sure this will be a great learning experience for all involved), but please do not expect me to go "oh, sorry, I was wrong, here's the Wii U exploit" the minute 'cat /proc/cpuinfo' shows 3 CPUs. I would've been impressed if it happened within 2 weeks, maybe a month, but it's been 6.5 months to code a trivial exploit and get basic Linux brought up (nevermind actually getting SMP to work). I appreciate your perseverance, but you have to realize that this doesn't demonstrate that there is enough developer manpower to make homebrew useful.
Maybe the 30c3 talk will gather more developer interest.
