I assume you are talking about Tony? and the issue he reported on saturday?

I am not sure whether we have any other person besides Neil here who can test the NDS build (knowing how to use an NDS emulator for this would be helpful), though you could try on the forums.

Anyway, a more classic approach to debugging this might be needed. First off, Tony,  does a binary you build from the 1.1.0 branch work? If so, it's likely that trunk has some issues; if not, your cross compiler setup has issues (e.g. you are using DevKitPro r30, and this new SDK may have introduced regressions in our code compared to some older SDK versions).

If it *does* work for 1.1.0, then it shouldn't be the SDK but rather a regression in our code base. I would recommend bisecting back on trunk between the 1.1.0 branch point and now. Of course this is made more difficult by the fact that Neil tends to update his port only after branching without backporting the changes to trunk immediately (Neil, this really makes figuring out when we caused a regression in your port a lot, lot harder :/).
So, in addition to bisecting, you may also need to figure out when we last merged NDS changes back from the release branch into trunk, and try before/after that. Possibly with some extra manual tweaks to get everything to compile.
