Item description

Revision History: (Included for reference)

Version 1.1
Date: November 1, 1995
U6: Checksum: 8311 (R - Regular)
Checksum: 6711 (B - Belgium/Canada)

Changes from revison 1.0:

Removed German Price Fixing, and updated Belgium Coinage tables.

After a player finished entering his/her initials
for a Pit Champion high score, the record time would
be displayed incorrectly at the end of the effect.
Nothing else was affected.

If the game was re-started while a ball was held
in the pit stop diverter, the diverter would remain
open until ball search.

When installing pre-sets "EASY" or "EXTRA HARD" the
word "INSTALLED" would not appear.

Version 1.0
Date: August 4, 1995
U6: Checksum: 4F10 (R - Regular)
Checksum: 2110 (B - Belgium/Canada)

This is the release of software for production.

This version uses sound revision 1.0:

Changes from revison 0.8:

Corrected an error in the replay system to made it impossible
to adjust Replay Boost to OFF.

In the diagnostic test menu, the coindoor G.I. string was
incorrectly stated to be in the WHT-GRN string. It now correctly
states the WHT-VIO string.

The 10-point switch located at the jet bumper arena exit did
not score any points; now it does.

This is an officially licensed replacement part. Please view my shop policies for more information.
