curious 4 reading bout ones u share!!!

I have a Famiclone called the Power Joy. The whole thing is built into a N64-styled controller, and includes a light gun built into it (the trigger is the Z button). The second controller plugs into the bottom "prong" and the cartridge plugs into the back- which makes it really easy to bump on accident. It can run on 4 AAA batteries instead of a power cable- but probably not for very long. The analog stick works as a second D-pad (which is good, because the D-pad on mine is dead).

Half of the games on the included multicart are unplayable because they use the wrong CHR bank, lol.

You can see a photo of it here
