Yeah but you need an emulater (sumthing to play it on). I use visual boy advanced. its easy to get just google vba and select the first 1. bout half way throuh the page youl find the download. now get a download 4 the game u want to play. fianally, open up the vba. u might find a notice. if it does come up just press run its never done anything 2 me. anyway on the vba bubble go file+open+the game= done! If you are a hacker like me u can use gameshark and gamegenie codes on the vba. ENJOY YOUR GAME EXPERIENCE!!
First of all you have to copy the cheat MUST BE ON then press on the vba "cheats" then "cheat list" , "gameshark" and paste it.!!! Then copy and paste any other code you want. Don't forget copu ALL the code.
