■ 3.2 Saturn peripheral standard format

■ Saturn Peripheral Standard Format Purpose

The Saturn peripheral standard format is prepared for the following purposes.

  1. Multiplayer can be controlled even if the peripheral data structure, type and meaning are different.
  2. Even if an upper word compatible peripheral is released in the future, such as an increase in the number of buttons, an increase in the number of analog channels, or expansion data, it is possible to operate multiplayer using that peripheral. You can also control previously released applications.

■ Saturn standard format types and data formats

Saturn standard formats are currently available in four types considering the above-mentioned purposes. Each is described below.

Saturn Digital Device

A device consisting only of buttons represented by Saturn standard PAD.
Peripheral type is based on 0H and data size of 2 bytes.
As a feature of the format, 1st Data has the same configuration as the Mega Drive 3 button. Compatibility can be secured by building an application so that the application can be controlled with just 1st Data. Table 3.10 shows the Saturn digital device format.
