I'm finally getting my rear in gear and am going to make that SNES/NES dual cartridge Retro Duo portable I first envisioned way back in 2008. Initial concept sketch, probably won't stick to this much at all aside from installing the two cartridge connectors at a right angle to each other. You can see I planned on using a PSOne screen but I'm tossing that idea. NES cartridge connector sits at the bottom of the portable with the NES cartridge flush to the back. SNES connector is up at the top with the SNES cartridge jutting out perpendicular to the NES cartridge. It will be possible to have two cartridges inserted at the same time, but you'll need to insert the NES cartridge first: The third gen Retro Duo has finally gotten the dpad feeling pretty solid and non-flaky. About time! The first version had a TERRIBLE dpad. It's still not as good as an original controller but the black buttons are pretty cool. I'll probably borrow this color scheme - gray with black buttons and black button labels. I'm using a widescreen LCD I've had for a while so that helps cut costs. After extensive "testing" with the screen, I am certain no one would even notice the image is stretched in these NES and SNES games. Like hailrazer once said, a screen this small hides a lot. Wookie is going to help, too. His part in the project is to sit on the windowsill next to me and soak up the sun's energy until the SNESNESp is nearly finished, at which point he'll bombard the portable with the full power of the Solar Particles stored within his furry body. The portable will then have an estimated battery life of 3,000 years.
