NES Rad Racer Score RAM Location/Format
I've begun a project to parse out and store the high scores from certain 8 and 16 bit games in my Batocera cabinet.
Done about two dozen or so by either studying the CPU memory, or with the data from the fine folks at DataCrystal.
Working on Rad Racer, can't seem to understand what they were doing.
What I've been able to glean so far is that something is stored at $0031, up to decimal 83, hex 53
(Screen shots are from Mesen while game was paused)
At 84 it's rolled over to 00, and I can't seem to find any sort of multiplier
If I just do some random higher score.
Most games store their score contiguously, either as BCDs or hex values of the score 10 divisors. But I think there is some sort of multiplier somewhere else, since 1002 = 78 + (84*11), but I can't seem to find it.
