5. Recommended specifications to connect games smoothly

If the specifications are made exactly according to the standards so far, the following screen must be passed even when the game of “Disc 1” ends and the transition to “Disc 2” follows.

1. "Disk replacement message" on "Disk 1"
2. “Multiplayer screen” of BOOTROM
3. "License Sega Logo Screen" on "Disk 2"
4. "Title screen" of "Disc 2"
5. "Game record selection screen" of "Disc 2"

These screens are nothing more than an amusement for users in the flow of stories. Therefore, the following specifications are recommended to minimize these procedures.

《Recommended Specifications》

• When “Disk 1” is finished, create “Transition status data” to “Disk 2” in the saved data
• If the application recognizes the existence of the "migration status data" in the backup RAM, it will be read in preference to all (ignoring other records)
• When replacing a disk with "migration status data", the following minimum procedure can be used.

  (Existence of “disc 1” recorded as “normal data”)
  (Temporarily rewrite "normal data" to "migration status data")
  ↓
  1) “Disk replacement message” on “Disk 1”
  2) “Multiplayer screen” on BOOTROM
  3) “License Sega Logo Screen” on “Disk 2”
          (Recognition of “migration status data”)
                    ↓↓
  4) Immediate return to application (game play)
  ↓
  (Rewrite "Transition status data" to "Normal data" starting with "Disk 2")
  

  * You can skip “Title screen” and “Game recording selection screen” of “Disc 2”

  However, note the following points.

  ! ! Note! !
  “Migration status data” is data in a special state, and usually does not exist.

  * After “Disk 2” is correctly inserted, rewrite it to “Normal data” starting from “Disk 2” as soon as possible.

  * Take action when two or more "migration status data" exist by mistake
  (Determine priority by time stamp, provide selection screen, etc.)

  * In the backup capacity check at the start of the game, it is necessary to secure a capacity that also considers "migration status data" (the capacity shortage is found for the first time when the migration status is entered, and it is not possible to transfer to the next disk ... Be careful not to invite such a situation)

  * When this specification is adopted, the user should take sufficient care not to turn off the power while leaving the “transition status data” (separation that would not be strange even if the power is turned off when “Disk 1” is finished. Etc.)
