 A software accelerated (CPU-only) game engine for older computers. It uses a layer of abstraction, so different implementations can be ported to it. It primarily uses SDL2. This can also be used to more easily port the engine to different consoles.
 
-Compiles for Linux. If you want to compile for OpenBSD, run: git apply patches/openbsd/generic.patch
+Can be compiled for Linux, OpenBSD and Windows.
 
 > Prerequisites, Debian/Ubuntu:
 sudo apt install python3-toml libsdl2-dev liblua5.3-dev
