there's a difference between just putting old carts at 720p/1080p res like an HDTV does and properly upscaling them to said resolutions, i very much doubt the retron 5 does the latter, especially at @ $100
Well, yes. Getting a 240i video signal to 720 or 1080p is one thing.
But isn't the Retron heavily based on emulation? I don't understand why they can't just upscale nearest neighbour whatever video resolution they emulate to 1080p and pipe it out the HDMI interface, basically doing what a computer with a fullscreen NES emulator would do.
I kinda never understood the Retron: It's emulation, but they keep talking about dismantling older calculators to retrieve memory chips from them. Why would you need old memory chips if you're emulating most of the thing?
