I feel like the Saturn as an unlocked thing is still fairly new, and it's notoriously difficult to make stuff for. I bet it'll be a while.
Well mod chips have existed for over a decade, so that's not the case. If there were anything interesting to run, this just opens it up to more people. I don't think the Saturn homebrew scene will get any kind of boost ever, it really just becomes less useful for the purpose every year it gets older. Example: an mp3 player would have been a somewhat cool novelty homebrew 6 years ago, but today with subscription based services it's even less appealing than it was then. Like going from 5% appealing to 2%, lol.
