Precautions
• When a CD has not been inserted or if the CD door is open, the Multiplayer will
display the following:
• “Drive empty”
• “Drive door open”
• A game cartridge has priority of execution over the SATURN application CD-
ROM if one is inserted. To boot up the SEGA SATURN game disc, turn off the
power and remove the cartridge.
Differences in the Product Version and Target Box Version
• In addition to the functionalities of the boot ROM in the mass production version
of the SEGA SATURN, the target box version has functions for checking SCSI
devices and SIMM memory for debug support before starting the game. After
the SCSI devices and SIMM memory are checked and a file named
IP.BIN is
found, startup of the game is continued. See the Simple CD Simulator User's
Manual (ST-161-R1) for more details.
• With the target box version, the game can be started from the write-once CD
without using the System Disc.
