Cracking a C64 Game From Cassette: Livingstone, I Presume?

Cracking a C64 Game From Cassette: Livingstone, I Presume?

In a previous video we took a look at the crash in the Commodore 64 port of the Operasoft game "Livingstone, I Presume?", unraveling the cause of the crash and coming up with a live-patch to fix the problem. This time we learn how to "crack" the game from the original cassette so we can patch the game and save it to disk permanently fixed, rather than having to re-patch the game every time it's loaded. Check the video description for links to everything I reference.
