Now are you asking out of curiosity, or to gauge interest in new products (software or hardware) before you invest time and money into those projects? I seem to remember you used to be one of the original developers, looking to get back into the system so it would make perfect sense to determine if it is worth your time to develop new games, if anyone is willing to play / buy those in the end.
Sorry, I guess I missed your post when you made it Carlsson.
A bit of both really. I am working on a game, as time and enthusiasm permits, and have some other ideas too. I don't mind investing my time in the project as a hobby, but money is tight for me these days, and so far everything I have done has been with the WinArcadia emulator. I have no dreams of making money from the effort, but would like to cover some of the costs of buying a console and other hardware for test purposes, so wonder what sort of interest there would be in a new game, whether I could justify making cartridges, or just making binaries available for download and seeking support via Patreon. I might also make the source code and documentation available, either as a download or print on demand book.
I am also interested in exploring just what the console could have done if the the cost of rom and ram were less prohibitive back in the early 80's.
