We do support older versions of Visual Studio too. However, on this page we focus on building ScummVM with latest Visual Studio. Building ScummVM with older Visual Studio 2008 can require additional work not described on this page. | We do support older versions of Visual Studio too.

Simply open the generated solution file in "dists\msvc\scummvm.sln". Now you can ask it to build the desired configuration. By default it will build a debug configuration which is ideal to hack on ScummVM. | Simply open the generated solution file in "dists\msvc\scummvm.sln".

The easiest way to do this is to place the SDL2.dll file in the directory where scummvm.exe is (dists\msvc\Debug). There are multiple SDL2.dll files to choose from, depending on your build configuration. Simply pick the right one from the prebuilt libraries. For example, if you build a Win32 Debug configuration, you will need to use "libs/x86/Debug/SDL2.dll". | ||
