Ok so does anyone know about the screen? Is the 4.3 from a 2000/3000 possible? Or is there another larger screen that will work?
No, the go has its own unique ribbon connector.Its near impossible. I dont think a single person would figure a way to hook that screen up. And no, there isnt a way to get a bigger screen for the go.
I would look into a 2000 and get a plugin that automatically switchs to its AV out. Then hook a bigger screen. And there you go.But Im not sure there is a plug in that does that yet, but hey, you can request it, or make it your self.
Also, may I ask why you want to make the psp like 4x bigger? If your going to do that, why not just make a wii laptop? More emus and Wii game play! Also it will be about the same size too! Use the Hombrew channel to use the emus btw.
What ever you choose best of luck!
