I downloaded the .rar file for Wacky Races, then the Dizaynoyu...Launcher_x from this site, but I have no idea what to do next. Sorry if this sounds like a really stupid question but could somebody help me get this game running for me? I have absolutely no idea what I'm doing. There is a tutorial video on YouTube that supposedly explains how this is done, but there is no sound and the maker clicks so fast I have no idea what he is doing nor what he has already done. I can't find any other guides anywhere so if there is someone who can reply to this post with step-by-step instructions on what to do it would be greatly appreciated Thank you for your time, patience and assistance
