Not the coolest, but the one I enjoyed working on was a project to port Mortal Kombat: Dead Alliance game from GBA to a puny(but interesting) linux mobile phone. The linux phone had no graphics hardware acceleration where as GBA has. And I am no graphics expert, I am a generalist software engineer and there was no support or documentation* of the original source code and platform so it was super fun ;) * Don't ask me why, there were some business reasons.
