Childhood games, can we still play them now?

I used to play a lot of NES and Super NES games back in highschool, but never really thought that I can still enjoy them today.

Kung Fu was one of the games that I loved playing.



The birth of emulators allowed me to install this classic game on my psp as well as on my xda iis.
My peers at work were so happy about it, and copied the games onto their gadgets right away.

I still recall the Code in Punch Out that allows little Mac to directly fight Mike Tyson, its 007 373 5963.
