A1: When a number lights up, go with left analog to that number and press [ ], do this also by other numbers that light up, the list with numbers above let you see all possible combinations and the "lighter" ones are left to choose of, when you have 2-3 numbers, you can select the good one with left analog and press X.(you can only have a few numbers , then you must wait till you see the others and know the combination)

A2: When the sequence starts you have numbers lighting up on the bottom
panel,so when they light up press SQUARE BUTTON.
you need only three numbers usually.
make sure you got three numbers from LEFT TO RIGHT.
[31][65][96][EMPTY]
once you got those done press X BUTTON.
to the right of the panel,tells you how many codes you need.
[31][65][96][empty]>>>3
if theres 4 numbers once youve done it it automatically finishes the hack
above the panel you will see a timer move from RIGHT TO LEFT.
----
[31][65][96][EMPTY]>>>3.
you can stop the hack by pressing TRIANGLE BUTTON.
but you cant start the hack again.
what you need to do if you mess up is go and hack another comp
succesfully then return to the one you messed up with,this re-sets it
for another attempt,you can also go through a check point then back through the check point and do it that way.
it re-sets it that way also.
so basically you need to get 3 codes from left to right.
if theres 2 codes on the hack
[54][73][empty][empty]
you need the codes in those left slots.and so on.
the far right slot can be left empty,unless 4.
