What I mean is there is no off the shelf linux solution for that chipset, where are you going to get the Vrender docs from to support it? The same goes for the Mpeg4 decoder.
I'm pretty sure it is windowsCE only from Magiceyes because that chipset won't be so 'open' (although i'm sure the docs would show up eventually).
Look how long it has taken to get to grips with the gp2x hardware even with it coming with a linux port from day one.
No magic devs are going to appear to make psx, n64 and saturn - we don't even have a rewritten snes graphics core on the gp32 or gp2x after 6 years - it isn't as simple as just saying 'this or that will happen' it just does not work like that.
