Love your games as well! Have you considered packaging them for Steam and pricing at less than 5 dollars? (i.e. a single pack of all your NES games) - if you promote to a few YouTube retro influencers you might make a few sales. :-)
Thanks. I might sell some one day, maybe as a physical cartridge release as those have better margins. Mostly though I want people to enjoy my stuff, so a lot of what I release is free.
