Sega Saturn Software Development Standards, SOA version 2.0 5

• Special Considerations

For single player games, the game must support operation from any

one of the 6 peripheral ports when the 6Player is connected to Control

Port 1 (left port when looking at the front of the Sega Saturn). The

use of Control Port 2 for single player games is prohibited.

2.3.3 Analog Controllers

• Compatibility

Fully compatible with all games in digital mode as a minimum (analog

mode is optional).

• Peripheral Types

Mission Stick (and possibly other analog peripherals in the

future).

• SMPC Standard Format Type

Saturn Analog Device (see the SMPC User’s Manual for more

information).

• Special Considerations

The first 2 data bytes of the Saturn Analog Device Format are

identical to the first 2 data bytes of the Saturn Digital Device.

Therefore, the Mission Stick provides virtual compatibility with the

Digital Device format by inserting digital data in the Right, Left,

Down, and Up bits that correspond to movements of the stick. This 2-

axis movement is also represented by the X and Y analog data in

bytes 3 and 4.

Game producers/developers can choose to make their games

fully compatible with all available functions of an analog controller to

enhance game play (e.g., using the X, Y, and Z

analog data from the Mission Stick). Games can also support

additional peripherals that may be available in the future, but

that make use of SMPC Standard Formats. Examples would be:

• 6-Axis Analog Controller, which uses the Saturn Analog Device

Standard Format.

• Mouse, which uses the Saturn Pointing Device Standard Format.
