On an article at gamestar magazine I came across an Open Source Settlers like Game called Widelands.
According to the build information a port might be relativly easy for someone experienced in portinf C / SDL based titles.

In this old thread, a then-recentish OS4 port was reported to run with OS4Emu. Maybe the newer OS4 port runs with OS4Emu, too?

Thanks Andreas. Sometimes I think You are the one sitting in Back of Google , manually answering all those search requests ;)

Didn't know that there already was a port runnable in OS4Emu. I probably would have been glad to know time back.
The latest build for OS4 is from 2013 however, the latest build for Win from May 2019. The latest commits on Github from yesterday.

I made a similar comment years ago. Andreas must memorize everything on this forum and in the Amiga universe. LOL

@BeWorld can maybe help? They have ported so many games and programs over that use SDL2

:-)
this port need OpenGL 2.1 with shaders, GLEW and Boost library...
So i dont think it's possible

We would need an updated tinyGL then ?
