This is the Touchscreen test software used in the Nintendo Factory to test dsi units before they were send to stores. The original PCB and Case were broken and the original chip has been transplanted to another DS PCB to get it back up and running. The original shell and pcb will be included. The software will only run properly on an Nintendo DSI, the pictures show it running on my new 3ds xl but the software gets confused when you try to calibrate the touchscreen.
