Duck Hunt: Rules

For Duck Hunt, the maximum reachable level is 99. 
After that, the next level is "0", but not functional.

So for Top Rounds records, we will consider that 99 is the maximum score there.

Also, because this game now also exist in Wii U system (with different options), I strongly advice everyone to add a proof showing you own this game on the original NES system.
We now need this kind of information, for the most fair competition between members.
Thanks for understanding.
