Added an attempt, at least, at spotting the Activision titles. Which reduces back to only the one breakage, but this is getting a bit too much like spotting the hard-coded bytes.

Adjusted Super Chip test to look for two portions of 128 bytes. It now spots Dig Dug and doesn't acquire any further false positives amongst the tested set. So failure to spot the Activision stack-based paging mechanism is now the only remaining failure.
