Hey Ben! so, i was thinking. You've made portables before, but i think you should make another (another portable 
omg) but this time using the beaglebone black board. This would be a good option for emulation because it has a bit more RAM, and CPU power. The case would also be a new design by adding the "Clamshell" fuction, like the Nintendo Game boy advanced SP case (picture). Buttons = Bottom, Screen = well... top 
. So ben, I hope this would be something you are interested in doing for the summer solstice! (or around there!) Thanks ben!
