Street Fighter II problem

It usually tells you what is missing in a popup box and also has folders listed those are not realy folders but are the zip files it looks for the roms in

I would also use MAMEUI, but if you altready are just use the gui right click the game you want to play and hit audit that will also tell you what is missing, that game does not use CHD's though

At a guess you are missing http://www.emuparadise.me/M.A.M.E._-...Q-Sound/164687
