There were a few variations.
For the nes you could get an adaptor that took a nes game (for the lockout chip) and a famicom game, allowing you to play famicom games, that didn't have lock out chips. A few pirate/ unlicensed games went this route also.
I've seen a similar thing for the snes. I believe the super famicom had a lock out, so cant remember if this was required for those.
I used one to play SFII: Turbo months before it came out over here. Unfortunately it wasn’t very well made and knocking the machine while in use would cause the game to cut out & restart, which happened quite a lot during intensive 2p matches!
