SYMPTOM
Note: No game should use MK3
2.0 software. Reset problems
were inadvertently introduced in
this version. All games should
have version 2.1 installed.
When the left hand player chal-
lenges the computer, in the
middle of the game control is lost
and freezes in that position.

v2.1 KAHAL REsET BuG FIXED
When playing Kahal, if a player
holds down punch for 2 seconds,
then goes towards, towards,
down, towards with the joystick
& releases hi punch, game resets.
v2.1 FREE GAME BuG FIXED
When a player finishes a one
player game, Kano and Kabo
jump on the screen during the
end if there are game credits. If
at the point that they land the
player hangs on the 2 start but-
tons, he will be allowed to start
at the bottom of the ladder again.
v2.1 CREDIT MEssAGE
Maximum Credits Message is
printed in a different position on
the screen. Now it is located at
the top of the screen and does not
interfere with the other text.
v2.1 COMPUTER SMARTER
Computer is no longer a sucker
_ for combo moves when being
attacked from behind. Computer
used to get caught by players who
would hide from behind.
Upgrade your program to ver-
sion 1.5 prior to this repair (see
figure 1 for PROM location).
Note: Check to make sure that
the PROMS that you are replac-
ing are the same speed as what
was taken out (27C040-10). In-
stalling a PROM with a speed
lower than 100 nano seconds, will
cause freezing. resetting and
strange problems to occur.

AnDmONAL PROCEDURE
After the PROMs are replaced,
a little work has to be performed
to the control panel. Attach two
lengths of wire from the power
supply logic ground to the com-
mon ground of the joysticks of
each player. This is done because
the ground coming from the har-
ness which is plugged directly
into the computer board, some-
times loses connection thus,
player control is lost.
The PROM upgrade corrected
program problems that were
over looked in version 1.4.
