You can now buy your own copy of Hamburgers En Route To Switzerland for the Virtual Boy at http://uncletusk.com
It is 10 levels of milkshake shooting action. It comes with a box and instruction manual. I'll add a picture once my copy comes.
I also changed my avatar. It is Uncle Sam eating corn flakes. I thought it was fitting for this time of year since the Fourth of July is soon. I will change it back once it ends.
