Hey, I'm 14 too, but i can type like a civilized person.
I'll "start" at the "beginning"...
In 1991, Microsoft released Windows 3.1. It's a totally awesone operating system. Think Windows XP but without all the pretty colors. From then on, computer files were given an "extention" which is a "." followed by "3" or 4 letters. This tells your computer what the file should "be" opened with. ".gme" is the extention for Playstaion game files. To play one of these in "GT2", you need to download an "emulator" that will let you play Playstation games on your "computer". EPSXe is a good one. I don't feel like "typing" anymore.
