Nintendo VS. System RP2A04 Chip

Program Revision
By Nintendo Service Department
Rednond, Washington
On the SUPER MARIO BRQS game set, there is
no telling how many calls I have fielded
about the use of the RP2A04 chip. To make
matters clear, like the instructions that
come with the kit don't, is that the
RP2A04 chip is used ONLY ON THE SI~E
PLAYER CABINEI' IN Pa>ITION 2J. THE RP2A03
PROCESSOR REMAINS IN SJ.
A program revision has been made available
for the first 300 PIAYCOOICE-10 units. Any
PIAYCOOICE-10 with a serial nurrber greater
than 300 already has this revision
installed from the manufacturer.
By
IN THE DUAL CABINEI' GAME, THE RP2A04 IS
NOT USED AT ALL! '!he reason is simple. '!he
single player cabinet uses the common area
ram that is normally used by both
processors with the SUPER MARIO BRQS. But
there is no processor used in the 2J slot
on a single player cabinet, and there was
a problem with the interrupt hardware on
the game board which made it, such that
the 8J processor could not use all of the
common ram that it needed, without a
restrapping scheme.
What to do? Well, to make it easier for
the operator, (to not use a soldering iron
and risk messing up his boards), they came
up with the wire in a package answer. Make
a chip and call it the RP2A04 and tell the
operator to put it in slot 2J on the
single player cabinet!
This program revision changes the coinage
options on the dip switches. With this
revision it allows the operator to add a
Prime Time bonus for 2 or 4 consecutive
quarters. The bonus is based on a
percentage and ranges from 8% to 100% on
both 2 or 4 quarter initial credit. The
percentage of bonus is operator adjustable
by the dip switch sett.ings.
A partial sanple of the new dip switch
table for Prime Tine bonus is shown below:

For those of you who have not installed a
GUMSHOE kit yet, be sure to pay attention
and install the 2 wires which provide a
memory boost when you install the kit, or
the game won't work right.

The Player/ Pin Skills
By John 'Root' Pilarchik
Pennsauken, New Jersey
One of the first pinball games I remenber
playing when I was a kid was a game by
Gottlieb called WAOON WHEEL. At 5 cents a
ganie for a five-ball play and five games
for a quarter, the machine offered a Free
Ball and Special shot. Score settings were
ar~und 900 points for the 1st game, 1200
points for the 2nd and 1500 points for the
3rd game; times are a changing!
Back then a quarter was alot of noney and
it had to last a long way. In order to
keep playing the ganie with what little
skill I had, the best way to get in plenty
of play time was to simply cheat! Many an
ashtray, wooden blocks etc. , were used to
raise the front legs up to a point where
the ball could get stuck and rack up
unlimited points. out of all the ways to
cheat, the best way was to drill a small
hole in the side near the flippers (no
metal back then) and using a small wire
you could rack up many games. Not rruch
satisfaction in this method, but it was a
great inexpensive way to learn how to play
th~ game and eventually learn to depend on
skill to beat the machine.
Today's games have come a long way since
then. However, the basic method and shots
to go for are nore or less the same.
Todays games have plenty of lights, sound
effects and fancy playing fields
(sometimes too crowded for my liking), but
the one nia.jor complaint I have is that I
come across many machines with weak or
poor rubber around the flippers.
Why doesn't someone develop a flipper that
holds up better without the player always
complaining to whomever to get them fixed
so often?
Good flippers with fast powerful action is
the firs~ key to a good machine; a
~hallenging playing field with good action
is second and a fair score setting (more
than one game on points is getting hard to
find) is third.
As a player, I am glad to see a wide range
of mac~ines which gives the player a good
selection to choose from. As long as the
November 1986
(12]
game has the three key elements stated
above, there's always the chance that you
might find another EIGID' BALL DELUXE
(Bally) on your hands, which this player
feels is the best machine I have played to
date.
I am always out there looking,
so keep up the good work!

Bally Midway GALAGA GG-4 Prom
By Sam Cross
Godwin Distributing Co.
North Little Rock, Arkansas
Yes, Bally's GN....AGA is an old game, but
there a_re still many of than out there,
and there has been a disturbing number of
boards that I have had the GG-4 Pran on
the Video Board go out!
'Ihe symptom that nost of the boards
display is in the video part, the main
part not being affected. 'Ihese problem
boards were not displaying some of the
lettering that is all of the same color,
such as the players initials and scores,
the challenging stage statistics, and even
some of the characters, like the bug who
cones down to get the player's ship.
If you have a board that displays some of
these problems, you might be somewhat at
ai:i advantage as to where to look; the GG-4
Video Board Prom.
