Yes, except that the checksum he's referring to is the global sum of a GB ROM. Some emulators don't like it when they're wrong. |

^ That's my preferred method. Losing corrupted save games sucks (for hacking at least) |

Or you can go in and just NOP the checksum routine out of the game ;D |

it's the sum of a certain list of values that is used to check the integrity of the data  |

Checksum= security guard for certain parts of the program it is meant to protect, in short. You can hack them though so that you can alter the protected part of the program  |

A checksum is something that checks if some bytes are a certain sum. Just like it says. It's to make sure the program stays unaltered.
There are ways around the checksum though, say the checksum is set to check three bytes, and they have to add up to $15 and the bytes are 05 05 05. To edit those and now trigger the checksum you could do something like 03 06 06. That would still give $15 and the checksum wouldn't complain. OR you could just point the checksum to another location in the ROM and always give it those bytes. But that's a bit more advanced. |
