I don't know much about market size, but I know that some developers are working on physical releases of new games for old consoles. Written from scratch, with new IP. I found references to a few on my own, then found this article that mentions most of the ones that I found: https://www.theverge.com/2017/5/9/15584416/new-games-retro-consoles-nes-snes-sega-genesis-famicom https://www.theverge.com/2017/5/9/15584416/new-games-retro-c... It says that the NES game Star Versus has sold about 300 copies since its release (in 2014, I think). So, there's an idea of the market, I suppose. I haven't found much in the way of information about its development, so far. There was a forum post that mentioned that it seems to use a new, undocumented memory mapper chip, which implies that the developer produced their own, rather than use the "donor" method that I suggested earlier. Just for curiosity's sake, an SNES game that was developed in 2013, and is available for purchase (I've no idea if they have the rights to sell it or not) : https://console5.com/store/piko-super-4-in-1-multicart-super-nintendo.html https://console5.com/store/piko-super-4-in-1-multicart-super...
