Did you extract the .rar using Winrar? I know some people run into that issue where it comes up as a notepad but I forgot the reason why. D:
i didn't- i never downloaded this i just downloaded it so im very confused
Yeah my games, as well as many others, compress their games into .rars to save space basically. You just unzip them using any sort of unzipping program like Winrar for example, it's the more commonly used one.
