Well this is what i found in my search for some old console game music
http://www.vgmusic.com/Not sure if u guys know about it this site but it has a vast collection of midi game music files for almost every game console (atari era all the way to PS 2 and X Box and even PC games).
Well hope u guys have fun looking into it and locating the games that u guys have played when u are young and getting the music midi for it.
Maybe if u guys have any recomendation from it, u can also just provide the link from it here to share on what u liked in the past.
