    Default Remove/Reset Friend Code in Animal Crossing City Folk rvforest.dat

    Hi all, I would like to reset/remove the saved friend code from a savegame so the game can request again to the server.

    PID should be in the offset 40 to 43 of rvforest.dat and if I have understood correctly the PID is what form the Friend Code so I should just edit that but the savegame becomes corrupted so reading around I have learnt there is also a checksum, can you help me please to edit/remove/reset the PID correctly or at least explain me how to edit the checksum too?

    Isn't there a tool to just reset the FC?

    Thank you in advance

    The servers have been shutdown, so I assume you are trying to connect to a custom one. There are actually several checksums throughout the save data (most of which are just a standard CRC32). The data you are trying to edit has a checksum at offset 0x20. The checksum is calculated over 0x111C bytes of data, starting at offset 0x24 and ending at 0x1140.
