Judge Dredd Pinball – CPU Rom [U6]

Note on sample/prototype machines vs later production run machines and the planet lock feature:

Early sample/prototype machines included a ring that would actually trap the balls during planet lock (AKA Deadworld).  This was deemed a maintenance concern and the feature was changed to a virtual ball lock on actual production run machines before the game was released.  Prototype games will have red boards.

L1-AT version is for production run machines that have added an aftermarket planet locking ring. Actual prototype machines have different wiring and need version L1. Both L1 and L1-AT do not contain any of the changes from later versions of the rom.  Using L1 version in a production machine will throw a switch error and credit dot.  L1-AT was created to fix this issue, and this is the only difference between the 2.  L1D is an unofficial version built off of L1At so still does not include “modern” revisions from L7.  I am not sure the behavior of any of the unofficial versions depending which sound version you are running.

Revision History: (Included for reference)

Judge Dredd version L-1D (Unofficial)

Changes from version L1AT (Unofficial):

— Corrected some switch names/numbers and spelling errors
— A.1 28 “Min vol. override”: default = Yes; was default = No
— A.1 32 “No bonus flips”: default = Yes; was default = No
— A.2 02 “Virtual locks”: was “Attract sounds”. This was a useless setting; there are no attract sounds at all. If you choose “Yes”, the first two locks are virtual locks, more or less like in L-7. You can use this of you sometimes want the better flow of L-7, without having to swap the roms every time
— A.2 05 “Ballsave time: 1-9; was 0-9. When set to 0, it would give you a 255 seconds ballsaver
— No more error message and credit dot when you don’t play (enough) super games
— Removed the anti drugs messages, incl. the additional ones on some non US settings
— The high scores 1-4 were not displayed correctly if they were over 9,999,990. This has been corrected
— Removed the quote “Drain shield deactivated” from single ball play
— Corrected the initialization of the safecracker count down counter.
— During modes, when a weak left ramp shot ends up in the ring, the countdown/timer will stop for max. 10 secs or until the ball is released from the ring
— Corrected the problem that occurs when a ball misses the planet exit switch
* Best case scenario: the problem is detected and corrected immediately and you won’t even notice you had a problem. This is usually the case if the problem occurs at the start of multiball.
* Worst case scenario: the problem is detected and corrected at the end of the game(s) in progress.
— Corrected multiball ballsaver problem. Sometimes you would get an almost endless ballsaver during multiball
— No multiball start when a mode is running. Some modes don’t go well with multiball and will prevent scoring the jackpot. And, when multiball ends, the mode will reset (start from the beginning) and the points you already earned during that mode will be gone
— No ball locking during Manhunt or Persuit. You can keep hitting the left ramp and see what you are doing and score the points you’re entitled to
