Hello

I apologizes for not being able to reply sooner. Our M.A.X. game is updated to 1.04 so if anything was not fixed we didn't fix it (we do not have source for those games). We posses only English version of our games. For sound and multiplayer functions we are using preconfigure DosBox that emulates proper devices - so yes, you can play it with your friends. Also with our MAX'es you can download M.A.X. 1 Game Guide and technical support. I hope this informations helps you.
