Castle Adventure: 2 Open Source Clones Compared
Castle Adventure is a from-scratch remake that reuses the same map as the original 1984 DOS game, running through a DirectDraw-to-Direct3D9/DirectInput8 compatibility wrapper (dxwrapper) rather than the original's legacy DirectX APIs. Seed7 isn't a dedicated Castle Adventure remake at all -- it's a general-purpose programming language and compiler project.
