On the mainline blog I have introduced a "new game" MILLI MUT8 (mutate). I added magic sauce to make the DDT mutate and splat across the screen and attempted to change the 'BONUS AT' message on the bottom of the screen to 'NEXT BONUS AT' and added a millions digit. Everything works except the functionality of the millions digit. The digit displays, but at the n,000,000 point crossovers/rollovers the millions digit continues to increment out of control. The code is confusing [to me] in many ways. The scoring could use 3 bytes to store 6 digits of score. For sure, at least in one point of the code, address $06C4 stores the 100K and 10K scoring digits, and it's possible that $06C5 stores the 1K and 100's digits and it's possible that $06C6 stores the 10's and units score digits. So I tried to add those 3 bytes and when zero, increment my new millions digit. But it doesn't work as you can see in this game sample when you play to 1 million points the millions digit increments out of control until 10K score points later. My code has a different version which detects 990,000 which doesn't work either, of course, but actually seems to look better than the other options I tried.

Once this issue is solved, another item I couldn't find is on the select screen to select what level to play at, the Select Starting Score should go from 10,000 thru 300,000, but when you achieve over 1 million points the Select Starting Score should always be set to 300,000. If your game ends at 1,200,000 the Select Starting Score sets to 200,000 instead of 300,000. I don't know how/where this is done.
