10-11 Reliability of Data (Required)

Caution
Because the reliability of data contained in a Controller Pak can't be verified by N64 hardware or the N64 OS/Library, the reliability of this data must be verified by the game.

Discussion
Data storage cannot be assured if power is interrupted or if the Controller Pak is removed during write access.

Examples of measures to prevent destruction of back-up data are:

  1. Detection of errors ... Checksum / CRC.
  2. Detection of abnormal data by the program.
  3. Check the Controller Pak for brand new data or destroyed data.
  4. Writing completion flag.
  5. Back up the saved data (write it to two locations).
