I have made a website for people to play Nintendo Game Boy games on but now the hard part is getting the Game Boy games onto my site for people to play. There is a website called PlayR that lets you play games on it. I do not know how they got Game Boy games onto their site. I do not know that much about how to do it, I think it involves buying the actual game and then Downloading it to you website, or maybe downloading Game Boy games from a website. Can you please tell me how to do this step by step. Thank you for your help.

It sounds illegal to me. Do you own the Rights or have expressed written permission from Nintendo to post their games on your site for others to play? Are you paying Nintendo "royalties" just as radio stations do when they air artists' songs?
