TAF high score bug. Software or machine.

At league night someone put up a good game on TAF of 690M and got the GC on the machine. After putting in their initials, the score came up as 4690M in the HSTD.

Anyone seen this before? Does it indicate bad memory or is it some software issue?

Bad memory or bad board probably. If everyone’s pretty sure they didn’t actually get 4B and the rest of the score is accurate, there’s definitely something fishy hardware-wise. Scores in that era are stored in BCD (binary coded decimal) so it would just take one bit being off to make it a 4B score.
