Well, I'm a novice in this respect, but I can certainly try and help out in various ways. > >From a quick google it appears there are a lot of variants of JZ4730 > > netbook, which is pretty cool!

The jz4775 is interesting from an open hardware perspective because, although it doesn't offer lots of fancy functionality for demanding users, it also doesn't rely on difficult-to-support functionality such as PowerVR which, as you probably know, doesn't have the best reputation amongst Free Software developers. > The JZ4770 is being worked on by the guys behind the GCW Zero games > console that is built around it, and we've started to consolidate & > share more code.

Yes, I've had some pointers from the people doing GCW-Zero software development. A lot of my own confusion has been knowing whose repositories to follow.

Yes, I think the latter option is the way to go. My Internet connection is not that bad, so it all should work, but fetching would probably have better chances of success. Thanks for following up!
