One Bad Byte Broke This Game: Commodore 64’s “Livingstone, I Presume?”

“Livingstone, I Presume?” is a puzzle platform adventure that had me entranced as a kid. Unfortunately, the Commodore 64 version I played always crashed at a particular point well into the game. I thought it was a bug in my pirated copy, but later I’ve learned even the original store-bought version had the bug. Today we take a look at the game and the cause of the crash, and see if we can fix it and get further into the game.
