It's a little bit sad, that the minimig is a one man show at the moment
Sources are there, feel free to hack around.
The Apollo Team has announced the "Standalone Vampire2" with1 GB RAM and the Apollo CPU. I see the danger, that this could become a successor to the MiST like the MiST became a successor to the original minimig.
Danger? Why on Earth is that a danger?! If they manage to pull it off, great!
I wish there would be something like the "Minimig Team" to drive the minimig forward. Amiga is by far the most important core on the MiST.
For YOU maybe, for others it is not, and the current Amiga AGA core is plenty usable, you cannot really expect it to become much better, just a few fixes and perhaps networking and (low res) RTG.
