OK, so here are the changes Spooniest and I made in Project II v2.40, in addition to the older Pastebins.
I need to catalog these along with the initial changes for 8.bit.fan next.
Some of those changes I had to make a quite a bit different as nothing I did would work to make it all fit. Eventually I did, and I really like the results so far. I should have cataloged them myself, but somehow I got it all to work in Bank 1 and 2. Now onto Bank 3!
