In this article I am going to look at ways to play the daddy (probably a grandfather by now) of all FPS using a modern system. The Windows 95 version will still work on XP (as long as you don’t want to use a USB mouse, the DOS version has not worked since Windows Me) but if you have Vista or Windows 7 you can pretty much forget it, I can’t even get the launcher to work on 64bit Vista Home Premium. There are a huge number of ways to get it working, but I am going to limit myself to my favourite 3, PrBoom, jDoom and DOSBox. All three of them are good, they all have their benefits and disadvantages, but which is best? There’s only one way to find out!
