It was very difficult before the introduction of the external dat file for highscores. It should now be possible to use the format it uses to do something like that.

Actually it's still very difficult.... the hiscores.dat is just for a very limited number of games that don't save highscore data (because the original machine didn't have battery backup). The data in the hiscores dat is still completely unstandardized and hard to parse. You know which data goes to what game, but not what the data contains, how the data is encoded, or even how many scores that are saved.
Even if you did manage to parse the hiscores.dat, that's only about 100 games(and I think that's a high number) out of 4000.
Your idea is a great one, I just thought of it a year ago, tried it, and decided it wasn't worth the trouble.
