Wow, this is pretty cool. I credit it up and I see $15 gets incremented. When the game finished for me, I see $1E being incremented. Oh, I think I figured that out. In the accounting test screen, it counts the game played in a "time length of game" slot. So my game obviously took a different length of time than your game and incremented the appropriate memory spot.

When I go to edit, I get it overwritten too. Bummer. Anyone know how to get around this?
