Since 2015, I have been asking for a re-release of all 3 games on the Wii U (the Switch did not exist yet) and the PS4. And let's throw in Xbox One as well (though I doubt a small Japanese company would be interested).
I have barely played the games at all for a while, and I would start again if they were re-released on a recent popular console. I imagine the publisher is holding out for a new Sony handheld, though I think PS4 and Switch wouldn't be amiss for now. PS5 probably wouldn't be a bad move either in addition to those of course. Maybe you could add those?
Edit: Done. Contributed the $8.
