Street Figher 2 (obv), TMNT, The Simpsons....
I'm playing them now as well on FPGA hardware thanks to the scene out there working to reverse engineer the original hardware and preserve them. Still waiting for an X-Men port though.
Lately I've been discovering that a bunch of classic NES games were arcade ports and I never knew because I had never seen the arcade versions, like Contra, Bionic Command, Strider, Castlevania (Haunted Castle)....
