Would you like to supersize your DS screen? Well this hack allows you to create the ultimate jumbo DS screen.
It’s a Nintendo DS hooked up to 2 Tablet PC screens, using an FPGA in between to do some translation magic. Pen input from the Tablet PC screens is sent back to the DS.
“The closest match I could find to the DS LCD is Sharp LQ030B7DD01. You can find a datasheet Here. Aside from RGB, the only LCD signals I needed to use were DCLK1 and GSP1 (everything is conveniently labeled on the DS PCB). GSP1 is vsync, analogous to SPS in the datasheet. I find hsync by counting clocks (263 per line).
If you need the actual hsync signal from the DS, you’ll have to find it yourself; I don’t know which one it is.
The bottom screen data is latched on rising clock edges, top screen is read on the falling clock. I had to buffer a full frame in ram because screen timings didn’t quite match up (incidentally, this also made adding the screen capture ability very easy).”
