Wii Programming Guidelines
7.2.6

Restriction on Contents of Data Written to Wii Remote Memory [Required]

Store data in Wii Remote memory in such a way that it will not interfere with game progress if data is
lost.
This requirement is due to the fact that there is a possibility that data in Wii Remote memory may be
overwritten when another game is played.
Only use Wii Remote memory to store data that can be recovered from data in Wii system memory
when data is lost or to store temporary data that will not interfere with game progress even if lost.
7.2.7

Checking for Errors in Wii Remote Data [Required]

When using data from Wii Remote memory, be sure to employ one of the following methods to check
for errors:
•
Data duplication and error checking (recommended).
•
Error correction capable of recovering from errors when contiguous 8-byte sections are lost.
However, there are no plans to provide error correction capable of recovering losses of contiguous
8-byte segments in future Revolution SDK releases.
7.2.8

Message Display When Writing to Wii Remote Memory [Required]

Be sure to display a message such as "Do not connect to or disconnect from the extension controller"
to prevent the user from inserting or removing the extension controller while writing to Wii Remote
memory.
This is due to the fact that some data being written to Wii Remote memory may be corrupted if the
extension controller is removed or inserted during a write operation.
7.2.9 Message Display When Loading Wii Remote Memory [Recommended)
Be sure to display a message such as "Do not connect or disconnect the extension controller" to
prevent the user from inserting or removing the extension controller while reading Wii Remote
memory.
Data read from Wii Remote memory may be corrupted if the extension controller is inserted or
removed during a read operation.

7.2.10 Error Handling When Writing to Wii Remote Memory [Required]

Be sure to perform a verification after writing data to Wii Remote memory. If an error occurs during
verification, attempt to re-write as many as three times.

7.2.11 Error Handling When Reading From Wii Remote Memory [Required]

If an error occurs while reading data from Wii Remote memory, either attempt to re-read as many as
three times, or use error correction.
