5-1 MPAL Compatibility of Software for North America Markets (Required)
5-2 5-2 Confirming TV system used with osTvType (Required)

Description

North American software must be compatible with both NTSC and MPAL formats.

Reason

Games whose market destination is the US must also work on MPAL systems (Brazil) because these games may be shipped to Brazil.

Reference

Remarks

The TV system can be confirmed using the global variable osTvType.

0 ... PAL

1 ... NTSC

2 ... MPAL

Description

The value contained in osTvType must not be used to automatically switch the TV system from NTSC to PAL or PAL to NTSC within the game.

Reason

When a game title is created for more than one television standard (NTSC/PAL), a Game Pak must be configured, separately, for each area in which it is licensed. A Game Pak must not be configured for both NTSC and PAL.

If the game detects a different TV Type by using osTvType, the game must be stopped before the developers' logos and the license screen are displayed. The game must go into an infinite loop with a blank screen or display a message indicating a system error and go into the loop. If a message is displayed, we recommend that the following message be used for standardization:

"This game is not designed for use on this system."

When a game is created for the North American market, Programming Caution 5-1 "MPAL Compatibility of Software for North American Markets (Required)" must also be observed.
