One of the main problems faced by hackers and modders creating portable versions of home consoles is, well, portability. Making something you can hold in your hands isn't exactly an easy task, but creating something that also fits in your messenger bag is a tall order, especially when hacking together a handheld version of something with a disc drive.
ModRetro member Jonathan Shine's solution to this problem is as ingenious as it is simple: If the disc drive is too thick, don't use it. The Envision, Shine's homemade portable Gamecube, kicks spinning media to the curb in favor of an SD card loaded with what we're sure are completely legal and legitimate backups of games he already owns. The device measures approximately 1.375 by 6.5 by 4.125 inches and will run for 2 to 3 hours on a single charge.
