I'm really not sure what good an open source console is. Someone would
have to explain that to me a lot of times to get me to understand it I
think. We have PCs for cheap and nice USB controllers...

On the console issue, I don't care all that much about running X
(yet). As long as the thing boots multi user, I can find a use for it.
Of course, it becomes a lot more useable once X is working. Then you
have something like a PC alternative.

I had no idea I would break my EULA if I did this stuff. Not sure I
care too much, but that's not a good way to try to start a new port of
NetBSD either. Ugh. I really have a hard time with an EULA not letting
me do what I want with their hardware as long as it's for my own
purposes... Seems to me it would be a nice thing to have a real
operating system running on these, but the game companies could care
less of course.

I'm interested in following along with any GameCube updates for
NetBSD. I can test stuff after I figure a way to boot (I knew about
psoload too, but I'm not buying it just for that). Maybe I can start
learning code enough to hack hardware someday... I'm cracking the
books again...
