My checkout was from July, a little over 1 month after the 0.73 release. When doing a new release, I usually go over all the patches and fix little things so the 0.73 -> 0.74 is not my way but I guess it can be done as well 😀
So this can be done in dosbox ?
I guess it can, but I like my SDL solution better since only the window handling is switched to GDI (actually the same codepath as OpenGL, just without the OpenGL context)...input subsystem then still uses the directx codepath. Using SDL_VIDEODRIVER=windib also uses different input codepath that used to be problematic at some time with dosbox 😀
Do you have OpenGL-HQ patch for SDL that builds on Visual Studio ?
No, but I believe the code should be buildable with VS. What is probably missing is the header generation...you should use mingw, compile, make sure asciidump.exe and hexdump.exe are built and all those SDL_openglhq_pass*.h headers generated. Then simply add these generated headers to the solution and build with VS. Or if you have time, add asciidump and hexdump building as a prerequisite in the solution and make sure they generate the headers before SDL is built.
