4.2.2 Wild Card Usage Restrictions (Game Versions)

When using wild cards for game versions, there are advantages and disadvantages to using and not
using them (when given explicit instructions). The following are some examples. Please review them
and select one or the other for use.
A When the Game Version is Explicitly Specified
Advantages
•
The corresponding Game Disc versions have a one-to-one correspondence, so it is sufficient
to debug in that particular combination.
Disadvantages
•
When there are future version changes, it will be necessary to upgrade the version on both
Game Discs. In other words, if Game Disc 1 specifies Game Disc 2 version 0, and Game Disc
2 was modified to version 1 after it was sold, then once Game Disc 1 had been modified, the
versions on both Game Discs would have to be upgraded and resubmitted.
•
When a group of friends have their own copies of the same game and the versions are
different and two friends switch Game Discs, they will not work properly when Game Disc 1
and Game Disc 2 are exchanged.
•
An identifying mark will be required on the label so that the version can be identified.
B When a Wild Card is Used in a Game Version
Advantages
•
Independent version upgrades can be released at future dates on their own Game Discs.
•
Game Discs with different versions will keep running when they are used together, so friends
can switch Game Discs without any problems.
Disadvantages
•
Care is required when releasing future version upgrades. In other words, when upgrading for
example, Game Disc 2, it will be necessary to assure that it can be switched with all of the
Game Disc 1 versions that are out circulating in the market.

game player to exchange Game Discs (see Section 4.4 "
