There's fheroes2 for that, an open-source port which mirrors most of the features of HoMM3's HD Mod.
fheroes2 was great for getting me unstuck on a self-imposed exercise of reverse-engineering the Heroes2 binary data format some years ago :)
It also brings “backwards” some of the QoL features of H3 which helps me, because starting on H3 means H2/1 always feel too Down Grady.
This is fantastic! I had no idea this project was a thing. While I love HoMM3 and the HD Mod/HoA, HoMM2 was the one I played first and will always be my favorite.
Broken Alliance map on Heroes II (was map from demo) is something I still pull out every year or so to sink a whole weekend on.
When H3 released, I expected H2 colored art with more pixels, but have been disappointed by the CG-like approach with undersaturated colors.
H2 keeps a hand colored vib.
Same. It was more polished than 3. Love everything about 2.
