Sharky, you are missing the point of the mini NES. It's not about the games. Shitty almost 40 year old games of which you can download by the thousands in minutes and stick them in 1% of your wristwatch storage capacity aren't the least exciting unless you played them when you were a kid, which if you did, you probably can already play them in a million other places right now.
The point of this device is to re-live the experience of getting a NES, having a cool box, connecting it to the TV, feeling the controller and just having that nostalgic feeling bring back memories.
I can't experience that on a shitty atGames plastic block with shitty sound chips and shitty wireless controllers that feel like shit, all connected in glorious RCA so that it looks even shittier than it did 25 years ago.
EDIT:
I want a small MegaDrive that looks like an actual MegaDrive. I want highquality landscape picture (HIGH DEFINITION GRAPHICS) through HDMI. I want to feel the BASS through my subwoofer, cristal clear stereo sounds. I want those robust Sega MegaDrive controllers, fitted with modern USB leads. I want to relive the MegaDrive experience as if it was released today.
