Saving NES High Scores?

[Tempest]

Is there a modern way to save high scores on NES games (specifically the early original launch titles like SMB, Kung Fu, Donkey Kong, etc.)? I'm using a real NES with a Powerpak cart, so I'm wondering if a high score can be saved to the CF card and loaded when I boot the game back up so I can see what my old score to beat was.

 

EDIT: Looks like save states might be the only way to accomplish this. Too bad they're a pain in the butt on the Powerpak

As long as atariage is around, this is a good way.
