OK. Recently, I've been trying to do something with ‘Return to the Roots’ on AOS4. The ‘s25edit’ editor creates maps that seem to be compatible with the originals. I'll check if everything works. When it's ready, I'll be able to share it.
@McFly You're welcome, if I finish it, I'll share it for free, as always.
If there are any elements missing for a complete port of Settlers II for AOS4 (including the editor), this is a great opportunity to celebrate the 40th anniversary of the Amiga and the release of the long-awaited port of Settlers II for the Amiga. As usual, there are still many things to check and ensure compatibility with the original Settlers II port, but... Here's a short video showing how I'm testing various things and what's currently working.
