Breathing new life to old DirectDraw games

An anonymous reader writes: I bought a bunch of old Wing Commander games for windows, and these use DirectDraw, which Microsoft has deprecated. They don't work too well under Windows 7, so I ended up reimplementing ddraw.dll, using OpenGL to output the games' graphics. I wrote an article describing the process and all the fun workarounds I had to come up with, and released all related source code for others to hack on.
