Hey all, here's a quick update on the state of things. I haven't been able to work much on linux-wiiu due to real life (and that's likely true for the other devs too), but Quark and I have been working on a better solution for installing Debian than finagling around with tarballs and images and all that *fun* stuff. I'm currently cleaning up the Linux side of things right now (chroot is a royal pain), and Quark's been off bug hunting in linux-loader to implement support for a few bootloader features necessary for a clean installer. (They're not features you'll see on the surface, so don't worry if nothing seems to look different.)
@depaul: regarding emulators, go ahead! I've actually been thinking about trying a few myself. GCC is throwing internal compiler errors everywhere, though, so compiling anything non-trivial from scratch is mildly annoying at best and awful at worst. Anything needing a recompiler is probably a no-go unless someone's written one for PPC, so PSX and N64 are probably out for now. You could give NES/SNES a shot...
@Joom: sadly no wireless yet. rw's the one mainly working on this; I'm not in the loop about how it's going right now. Use a USB-Ethernet adapter for now.
