Missile Command saves it’s high scores with all names first, then all scores, rather than cycle by name,score,name,score… A few things to note. 3 bytes for name, 3 bytes for score. The score is saved as decimals and in reverse order so 50 69 00 is 006950. In the system I’ve written this I would assign as “dr” for decimal reversed. However the scores themselves are in reverse order with lowest score first, same for the corresponding names.
Seeing that I was missing a few characters and couldn’t be certain that the all the characters related to ASCII, I loaded up Missile Command and got two new high scores.
Testing a space shows it as 5B which would be after Z in ASCII,
