Double Dribble Password Book

Double Dribble disk did not contain any on disk copy protection.
BUT instead uses a manual/code book look-up. (SEE Below for the photos)
When you boot the game you immediate get this black screen below.
You need the RED Code sheet to enter the 4 digit Password to start the game.
In this case for C07 you would enter 8467, then the game would start.

Here is the Original RED code sheet – RED because it was hard to Photocopy back in the day. Special THANKS goes to Jerry Kurtz for this original:

Then I convert to B/W with Photoshop so you can print it out:


Neuromancer Code Wheel

NeuromancerPicPAXNeuromancer also uses a code wheel. When you use the PAX machine (see picture) you are given three access codes and you are asked for a verification code.

Here is an image of the C64 code wheel, which was not purple as shown in some photos.


I bought this game so I could take apart the code wheel and scan them in. So here is the PDF of the top and bottom for Neuromancer codewheel


John Madden Code Wheel

madden1 John Madden Football from Electronic Arts in 1989.






The game used a codewheel for it copy protection. Electronics Art used many different copy protection forms in the 1980s for it’s Commodore 64 games from Error checking to FAT Tracks on 34/35, to Pirateslayer and then to Codewheels and manual look ups.


After the boot screen and you select

Start Game you get this screen that

ask for your Madden Season Ticket


There was already a print out of the codewheel, BUT it’s pretty confusing look at this:  John Madden Football

SO I found a code wheel on Ebay and bought it to scan for my blog, here it is in PDF and PNG. Hope this helps someone. MaddenScan.PDF and
