The Ghosts and Goblins High Scores is quite a straight forward set of data, although with a much larger array of characters with upper and lowercase letters, as well as a handful of symbols.
The first 20 characters don’t appear to hold any data needed for the high scores, there seems to be a duplicated array of data for the highest score at the end. The scores are unsorted so need to be arranged based on score value. Each entry alternates between score and name, the scores are held as decimals and in the correct order, names are pretty much ASCII. Starting with byte 20, scores can be put into sub arrays of seven bytes, 0-3 are the score, 4-6 names.
The byte to character table starts with the first character at 1D for a “.” and the last byte is 7A for “z”
