STERN PINBALL SAM BOOT ROM [U9] 965-BOOT-SAM EPROM

Revision notes from readme:

VERSION 3.1 – RELEASED JANUARY 28, 2008 – IMAGE CHECKSUM: 4CF6

Changes since version 2.30:

INCORPORATES SYSTEM CHANGES UP TO AND INCLUDING SYS. 1.39.
THESE INCLUDE:

During USB update, if a USB memory stick was inserted that had
no files on it, then the update code would crash the game. This has
been corrected.

When booting from EPROM, the ‘USB / BACKUP’ test menu entry is no
longer available. Backup of game code may still be performed from
the USB menu when booting game code from FLASH.

INCORPORATES SYSTEM CHANGES UP TO AND INCLUDING SYS. 1.39.
THESE INCLUDE:

Boot from EPROM now honors all factory defaults, as if factory
reset had been performed for the current dip switch settings each
time the game is booted from EPROM.

Fixed a problem with changing the dip switches. When the dip
switches were changed and the game was rebooted, the system would
not install the proper adjustment override values associated with
the new dip switch settings. This has been corrected.

Updating the game code no longer resets the Tournament data, if
possible.

CPU/SND BD II Games Affected:
Terminator® 3, The Lord of the Rings , Ripley’s Believe It or Not!®, ELVIS®, Harley-Davidson® 3rd Edition and The Sopranos®

Symptom:
No sound or static and noise in place of normal sounds. These symptoms typically occur after swapping sound ROM’s between different model games using different versions of the Operating System (O/S) (see table below).

Explanation:
T3 was the first game to start using the new White Star CPU/Sound II Board (SPI Part Number: 520-5300-00). This PC board utilizes new hardware in the sound section. This hardware required a new Operating System (O/S) in software that has been continually improved and updated since T3 . This has created some compatibility issues between the different versions of Operating Systems. One example would be games using sound ROM’s programmed to work with O/S 5 will not work correctly in a board programmed with O/S 4. The version of the O/S can be identified by the number of times LED1 flashes upon power-up (e.g. The LED1 will f l i c k e r then flash 4 times = O/S 4, … 5 times = O/S 5, etc.). Note: Color dots** are used on the IC in position U8 to also determine O/S Version for boards.

This new version O/S 8 will not improve the sound of a working board with an older operating system, it only corrects the compatibility issue.
