GamePad Update #2 I'm considering the idea of making the instructions for the GamePad in a program called LDD: Lego Digital Designer. What this program allows me to do is make 3D Lego modeals on my computer. The instructions you will receive for the GamePad RV4 will not be for the original GamePad RV4. The structure is sronger and has an added stylus port, alongside the already existing two game cartridge ports and stands.
