Note that in either case, we recommend making it possible to save data before switching Game Discs,

for the following reasons.

•

Data loss can be avoided if there is a Game Disc read error after the switch.

•

It will make debugging easier by saving the data to the Memory Card before exchanging the

Game Discs. When you have a bug either during or after the Game Disc exchange, you can easily

reproduce the bug using the saved data. If you don't save the data before the Game Disc

exchange, you will have to begin game play from the Game Disc 1 again, to reproduce the bug.

Caution

File structures that were open prior to the exchange will contain old data, so please do not use such

data after the exchange. Even if Game Disc 1 and Game Disc 2 have files with the same name,

please be sure to re-open them. To be safe, we recommend closing all open files before switching.

inserted during the exchange it will be treated as a correct Game Disc and the exchange will be

approved, when the other three Game Disc ID components (i.e., the Game Code, Company Code

and Version Number) are correct.

In the following section, we offer some precautionary statements concerning wild cards.

Wild cards can only be used on game versions (not on Game Codes, Company Codes or Game Disc

numbers). The reason is that if wild cards are used, the operation check combinations become

enormous and cause a lot of problems.

If you are nevertheless considering the use of wild cards for the following elements, be certain to

discuss the matter with Nintendo in advance.
