2. Multi-terminal

All software for Sega Saturn must work fine on multi-terminals, regardless of the number of players supported .

1) Specifications

• "Multi-terminal 6" is a multi-tap with 6 input terminals. By connecting the multi-terminal 6 to both the main body terminal 1 and the main body terminal 2, it is possible to connect a maximum of 12 input peripherals.

  * Connecting a multi-terminal to the terminal of a multi-terminal does not have to be supported because it is considered as unconnected in terms of hardware .

2) Multi-terminal setting principle

When connecting to a multi-terminal, the number of terminals and the number of players that can be played will increase, so the following principles, which are an extension of the <Principle for setting corresponding input peripherals>, must be observed.

* Reversing the operation number means that the operation number should be assigned in ascending order from the one with the youngest terminal number, but this is not the case.

* The terminals used do not necessarily have to be continuous, as long as the operation numbers are not reversed. (It means that there may be a space between the terminals used)

* This connection example (2) is not encouraged. In principle, connection example (1).

3) Checking the input peripheral when using the multi-terminal

Check the input peripheral when using multi-terminal. As a general rule, "1. Basic items" will be applied to the parts where the contents are not described .

<< Recommended specifications >>

◆ Checking the corresponding P (registration of valid terminals)

(b) Check at start

◆ Start application

• As a general rule, the start of play shall be made by the input peripheral connected to the terminal with the lowest number among the active terminals . (That is, the input peripheral connected to the main body terminal 1 or the terminal with the lowest number among the effective terminals of the multi-terminal connected to the main body terminal 1)

  * In a multiplayer game where you can participate in the middle, you may start from other than 1P.

◆ Determining the terminal to use

• When using a multi-terminal, it is often necessary to select the terminal to be used from a plurality of effective terminals. In such a case, the terminal to be used shall be determined according to one of the following rules.

  (I) Select the terminal to be used from the effective terminals , left-justified in ascending order of terminal number .

  (Ii) Select the terminal to be used from the effective terminals in ascending order of the terminal number (assign the operation number), but only the terminal for which the start button is pressed at a specific place such as the title screen is used .

  * In the case of rule (ii), an operation number may be assigned to an unused terminal.

  * When applying Rule (ii), the specifications must be such that the operation numbers are not confused. (The moment you press the start button, which player participated is displayed on the screen, and the reaction of the input is displayed on the screen, etc.)

◆ Checking for insertion and removal

• If the multi-terminal itself is plugged in or unplugged during the [Main Game], or if the multi-terminal is replaced with a single peripheral (and vice versa), it will not cause any problems regardless of the user's intentional negligence. Must do .
• In the case of insertion / removal other than the above, [1. Basic items] are followed.

(i) When pulled out

• If the used P or the multi-terminal including the used P is pulled out during play, it is judged that there is no input state . (Or do a "system pause" and display a warning at the same time)
  → The terminal used P or the terminal with the multi-terminal including the used P becomes the "vacant used terminal". There may be a plurality of "vacant terminals used". (See separate volume 2-5 to 2-7 in the figure)

(ii) When inserted

• When the corresponding P is returned to the "vacant used terminal" as a result of removing the used P, the input is restarted .
• If the multi-terminal including the used P is pulled out and the multi-terminal containing the used P with exactly the same configuration is returned to the "vacant used terminal" (main unit terminal), the input is restarted .
• If the multi-terminal containing the used P is removed and replaced with a multi-terminal containing the used P with a different configuration, only the corresponding P inserted in the "vacant used terminal" on the multi-terminal will be input. resume. (See Figure 2-8)
• Otherwise, it will not affect the game .

  * In both cases, wait for the release if in the paused state.

  * Even if a P other than the used P that was pulled out is returned, if it is a corresponding P, the input is restarted.

(iii) When replaced

• If the multi-terminal is replaced by one peripheral (or vice versa), the number of terminals will not match. The rules in that case are as follows.

  [When replaced with a small number of terminals] (multi-terminal → one peripheral)
  → It is considered that the terminal is the youngest of the terminals before replacement (see Figure 2-9 and 2-10).

  [When replaced with many terminals] (one peripheral → multi-terminal) → Only the youngest terminal among the replaced terminals is valid (see Figure 2-10).

Figure Separate Volume 2-11: When the number of terminals does not match (Part 3)

(iii) When added

In an application that uses a multi-terminal and has [Join in the middle], there is a possibility that the operation number will be reversed if it is additionally inserted.

* In principle, the multi-terminal setting principle allows there to be space between the terminals used, and also allows additional insertion during the main game when there is [Participation in the middle]. Therefore, if it is additionally inserted into a vacant terminal, the operation number may be reversed.

In this case, the following rules shall prevent the operation number from being reversed.

• Ignore the ones that are additionally inserted on the left side (younger number side) than the terminal with the largest operation number . (Interruption to the already assigned operation number is prohibited)
• Any additional terminal on the right side of the terminal with the highest operation number will be accepted . (Only addition of operation number is allowed at any time)

  * Most multi-terminal users assume that they are using this in a left-justified connection as specified in the instruction manual.
