Data East BREAKTHRU Coin Problem
Nintendo VS. SUPER MARIO BROS. Bug
By Data East Service Department
By Nintendo Service Department
San Jose, california
Data East's Service department has
received several connents regarding the
BRFAKTHRU conversion kit not giving
credits. '!he syrrptoms occur
intermittantly, (ie; once every 10 or 20
coin droµ,). '!he game does not give a
credit yet it will increment the coin
counter. This is due to the coin signal
not remaining active (low) long enough for
the CRJ to read the coin input line and is
caused by coin switches that have a very
fast response time.
The operators who have experienced this
problem have eliminated it by installing a
10 microfarad, 25 volt electrolytic
capacitor across each coin switch. This
will slow down the rise time of the coin
signal and allow the CPU time to see the
coin.
-
This modification is not recommended for
all BRFAKTHRU games -as rrost will not
require it.
Electrolytic capacitors are
polarized and will be destroyed if
installed incorrectly. Be certain that the
positive side of the capacitor is
·connected to the Normally Open (00)
terminal and the negative side is
connected to the Corrmon (ground) terminal
on the rnicroswitch.

vs. SUPER MARIO BROS.
It has been brought to our attention that
a bug exists in the vs. SUPER MARIO BROS.
program. This bug involves the flying
turtle between the steps just before the
flag pole on the final screen of World
6-1. '!he bug allows the player to position
the turtle in such a way that consistent
jumping on him will give very large
amounts of :EX)ints and many extra men.
In the revised program the turtle was
removed. This program revision consists of
just one EPRCM which is used in location
8A (or 2A). '!he version number for the
revision is e-3 and the Nintendo part
number is MDSU-21-8A-SM. This is available
on an exchange basis through any Nintendo
distributor.
