Sirius & plutos - where are they now?

Bit late for me, but I just discovered these fantastic looking games on the web. I was disappointed to see hat these were available only a couple of years ago but I don't see any available

Are copies still available that work on real hardware? Or whats the best way to get this on a cart?

Perhaps someone's doing a run for the Homebrew genre? I would be interested in getting this in cart form one way or another!
