game wont load

my games wont load my computer is "windows vista "how do change from rar file to nds file

Do you even have a flashcart like an R4 or an EZ flash? If you don't then it's pointless for you to be doing this, unless your using a PC emulator.To extract the .RAR file so it becomes an .NDS file you need to use Winrar or Extractnow..Winrar: http://download.cnet.com/WinRAR-32-bit/3000-2250_4-10007677.html
Extractnow: www.extractnow.com -Scroll down to bottom and click download-Once you unrar the RAR file, copy it into your flashcart's memory card or run it on your emulator.

thanks i will try that
