I found an issue on the game Ghouls'n Ghosts (ghouls). Just played a bit. I did not pass the first level, the boss killed me (yeah I’m that bad). But some way I got the world best score: 40,008,000.
I took 2 screenshots one from LaunchBox, other from the game score.
Now I’ve deleted the “.hi” file (ghouls.hi) and everything works as intended. But maybe is a thing that devs may look. Or maybe add a feature to remove/reset your own high scores form the LaunchBox database.
Hope it helps.
