Works perfectly on original NES consoles.
This game is guarantee to work on original systems only, should ALSO work on 90% of clone consoles as long as they are hardware type console, if you use emulation based system like a RETRO FREAK, RETRON 5 or POLYMEGA, there’s always a chance it may not work on those system.

3 teams are missing from the roster, Raptors, Pelicans and Grizzlies
