At first glance, this is some really nice mapping here. Also note the Day/Night system that was added. I also spot Leafeon, a Gen IV mon. Some other features that are not shown are new region, some new and remixed music, deletable HMs, fakemon “Eeveelutions”, added “custom” move machines called SMs, etc.
Read the full feature list in Original Source because it is just long as hell to fit on this page.
