I wonder if there is enough space for a Wacom 4" sensor board behind the TFT.
But Sadly the 4" sensor board doesn't really fit the PSP TFT.
Does anyone know of other sensor boards which fit the PSP display?

I dont know of one, but that sounds like a very interesting idea, espescially if you could link it to either the USB or the Serial interface and design some pretty cool games ala the nintendo DS
