Missile Command:  The score is six BCD digits: for player 1, it's RAM
location $F3 for the highest two digits, $F1 for the next two, and $EF for
the lowest two.  Add one to all those locations for the player 2 scores.
The current game number can be found at location $E9.  It appears that $E8
contains 00 if the game is not playing and 01 if it is, though I'm not
100% sure.

River Raid, I can't figure out how the score is stored.

Does anyone have, or can cook up, an emulator where I can play a game
while watching the RAM locations also onscreen?  That'd make this a bunch
