This kit includes: 1 Deadworld locking ring, 1 L1AT EPROM, 1 magnetic ball trough liner

If you have a sample version of Judge Dredd please mention so when ordering.

This kit restores the Deadworld ring locking holes and multiball function of the Judge Dredd prototype pinball machine, without the need to add or modify any hardware. The new software enables the full locking multiball feature and eliminates the switch 28 error; the only exception is the software is set for Free Play only.  The kit includes the ring and prototype software EPROM.    The new software enabling this feature is L1AT.  10 minutes to install.

(Great video of Judge Dredd game on You; just search for "Judge Dredd Promo"; you will see the original locking mod in action)

We've had a number of questions about this version. The bottom line is that the function of the hardware mods have been moved into the EPROM. It really is a simple as it sounds.

Troubleshooting Notes
The locking software is very sensitive to hardware errors in the game. A few typical malfunctions and their fixes are as follows:

Diverter does not load the ring when planet lock is available
 - Check ramp entrance opto
 - Check diverter

Multiball does not have all 6 balls
 - Insufficient balls in the machine
 - Trough divots holding up the balls (gently file and sand the trough ball lane to remove them)
 - Bad opto transmitters or receivers in the trough (check trough optos in swicth test)

Game keeps shooting extra balls in multiball, and ends ball with balls still on the playfield 
 - Check crane exit opto
 - Check that the ball exits through the crane exit opto

The crane opto has a relatively long gap; cleaning the transmitter and receiver can help.
