Mother of all FPS shooters, legendary Wolfenstein-3D has got a brand new incarnation. It is available on App Store, for mere five bucks. However, what’s interesting, one can spare $4.99 and build his own binary, thanks to available source code. In addition, John Carmack tells the story of porting - worth reading indeed.
It’s been over 16 years since publishing, but it still an interesting piece of code. In those days, developers needed to cope with hardware limits, processor speeds measured in megahertz and no fancy 3D acceleration. Not even linear access to frame buffer. Mobile programming resembles this good old days. Until we get new, much sophisticated, capable machines on our palms.
