nes systems are like what? 10 bucks refurbish or so. if you do metroid is the best. metroid is my favorite series besides zelda from nintendo. also use to love the megamen series as well. after X2 though i basically stop playing them. haven't seen good megaman game since legends.
also i would suggest sell all the iphones and ipods cause they all are horrible when it comes quality of the headphone jack. not the sound but the jack itself. my itouch i had i use my k601 on,everytime i move left channel cuts cause stupid jack. the adapter i use weighs less then a feather so it's not straining it. my cheap sony mp3 walkman i had never gave me issues with it's jack or any problems and that been kicked,stomped on,thrown,evrything and still functioning like a boss.
