>>11884268 (OP)Did it really have any serious shortcomings? Make the controllers connect with detachable plugs, that's the one thing I'd say it really needs at all, possibly make the cords a little longer.
Maaaybe give it more memory, but really, people got by pretty well with what the machine already had.
I think the one notable shortcoming is that cartridge elevator system in the NES, maybe make that slightly sturdier somehow. Or maybe give that some sort of eject lever of its own, since it would be a bigger benefit there.
