Heh, funny this should come up as just last weekend I discovered Doom Retro (doomretro.com). It has a few odd non-retro options enabled by default (screen shake on impact and translucent firey projectiles being the main ones that annoyed me, but they're easy enough to disable) but other than this is probably the closest to a "pure" DOOM experience I've had on a modern OS - not counting DOSBOX of course. It's also Open Source: https://github.com/bradharding/doomretro https://github.com/bradharding/doomretro
