9 Nintendo GameCube Memory Card

9.1 Nintendo GameCube Memory Card Compatible Application
[Information]
A Wii application does not need to be compatible with the Nintendo GameCube Memory Card.
Applications that do support Nintendo GameCube Memory Card need to conform to paragraphs 9.2
through 9.7, below.

9.2 Use of Write Functions Prohibited [Required]

As a rule, use only the Read functions. While we do provide Write functions for debugging, this must
not be used in the actual application.
Nintendo GameCube Memory Cards are available purely for read-only purposes, such as the transfer
of previous Nintendo GameCube game data.
9.3 Programs Must Not Depend on the Access Speed of
Nintendo GameCube Memory Cards [Required]
Ensure that programs do not run out of control or freeze due to a dependence on the access rate of
Nintendo GameCube Memory Card. This requirement is due to the fact that there is individual
variation among devices. In addition, performance will drop over time due to degradation.
9.4 Support for High Capacity Nintendo GameCube Memory Card
[Required]
Make sure the application will operate normally when a high-capacity Nintendo GameCube Memory
Card (maximum of 1019 blocks) is inserted.
High-capacity Memory Cards may have different capacities (total block number) or access speeds.
For example, if the application fixes the Memory Card capacity to 59 blocks, the program may freeze
or display incorrectly due to missing block number digits.
