Laptop sized portable SNES that got as far as a showing at the 1993 E3 before Nintendo pulled the plug. There are at least a few working models in existence. Use the cartridge as a reference; this thing is huge.
You can see it working in the detail with some Dragon Ball Z game. Screen looks pretty small, but this is 1993 we're talking about here. Pretty impressive for the time.
Would have been totally cool but I guess it didn't fit in with Nintendo's Gameboy marketing strategy. Too bad.
