I've been thinking about how lately a lot of retro consoles are being released with just game roms included with HDTV support and other things, like the new NES mini, the portable Neo Geo X and so on. But... why not release a console that can play the original games but has a "remaster" mode as an addition?
You could release a Sega Genesis with 20 or 15 games included with new modes, games with 60frps and no slowdown, widescreen support (if possible), retranslations, etc. Basically, something like Sega is doing with the Sonic android ports or the Sega Ages 3D, but released included in a console pack.
I mean, in 2016 there's no excuse to keep playing Double Dragon with thousands of slowdown or other games with the same bugs of the eighties when there's so much CPU power to overcome that hurdles and even improve the original experience (maintaining an original mode).
I'm not asking for polygonal remakes or 2D in high resolution, just the same games with new options or graphics that keep the same pixel art style and resolution. I think it's something that could sell very well and also brings something new to the old games to keep them fresh for old gamers.
EDIT: look, for instance, how much content was cut from a game like Forgotten Worlds:https://tcrf.net/Forgotten_Worlds_(Arcade
You could have the game with that content added or other improvements more.
