A fix for Anachronox that will allow it to run on XP: actually several fixes, the first one works for me..i have XP Pro SP 3 Nvida Card 9600 GT After applying all the patches, official and unofficial, Anachronox Fix To get it to play on Nvida cards currently (2013) turn ON Extension limits on the card control panel or Another method is - edit ref_gl.dll, find strings "GL_EXTENSIONS: %s" and replace "%s" to "%p". This is working for all Q1 and Q2 engine games, by the way. or rename anox.exe to mohaa.exe or anox.exe to quake3.exe or q3.exe. or buy it from GOG for under 10.00 US, as they have fixed the compatability problems. enjoy one of the most unique and wonderful adventure-rpg-action games around.
