I'm a computer technician and C++ developer creating some Open Source software projects related to the classic 1993 PC game Doom.
LZDoom is a legacy GZDoom compatible port with some extra stuff such as the fake splitscreen thing and RUDE is a very close to vanilla limit removing port forked from Chocolate Doom with some cool gameplay features. I also made the GZDoom vintage build, ZDoom LE and ZDoom32.
