Where do I find NGPC Developer Resources?

I have downloaded some stuff from some page, I forget where, but is there some developer forum or resource page or something for my favorite portable console? I want to start fekking around because of the free time I have on hand.

I bookmarked these a while ago:

http://www.devrs.com/ngp/

http://www.ahchay.com/html/buildproject.php?devdir=ngpcdev

The 2nd link isn't working though, perhaps they moved or just has been abandoned.

Good luck in your projects!

I also have:

It's a bit of a shame ahchay.com is awol, there was a good tutorial on there.
