Have you figured this out yet? my Yuri.exe doens't work, I'm trying to make it work in skirmish as well just to have fun around (I enjoy watching kikematemitos and byran vahey but heck no, not playing vs real players)
Would also like to know if it'd be possible to do it in LAN games with friends, so I can send them modified files to just have fun with (buildable techs at higher cost, a little like generals and their lategame income buildings)
