Release note


Adjustment 24 is fixed at the “Custom coinage” option.

Locks made are player individual. No hard lock stealing.
New diaplay/sound effect on virtual locks, where a “lock ball” is diverted to inlane for continuous play.
Compensation locks lit for re-locking balls removed by other players.
When re-lock is available, a plunged ramp will lock the ball.

When Contest game selected: Limited ball search. Locked balls are not released.

Sudden death random starting, removed.
On Sudden death completion, the ball is diverted to the right inlane.

A bug where starting multiball would occationally award a jackpot, fixed.

When Contest game selected: Roller motion mystery is a fixed sequence. Player individual.
Williams letter
Instant lock (if no further locks are needed for multiball, go to next)
Sudden death
Lite team
Lite atomic whip (if kickback is lit, go to next)
Jetter bonus
Bonus multiplier

The procedure goes down the list and selects the first available one that is not already awarded (this run).
A currently unavailable Instant lock or Lite atomic whip will be saved for later.
On completion, the list is starting over. This includes either of Instant lock or Lite atomic whip, which happens to be unavailable.

Why it rocks

Randomisation removed for better luck/skill balance in competitive play.
Sudden death may now be played for strategically.
The optimal physical lock solution for a fair multi-player game.
Bug fixes.


The rev. L-2 has compensation locks lit for stolen locks.
It is not perfect, and in any case rewritten for the new no hard lock stealing design.
Now you are compensated for own made locks only. And always.

Draining ball search’ed released locks (non-contest game) will have the game displaying the fun-with-bonus.
However, the game is not adding the points. And it is not ending the current ball-on-play.

A completed Sudden death is 8M total. The 6th shot counts for 1M on it own. Plus 2M completion bonus.


Great work as always, Soren


@soren for president !!!


Thank you Soren!!


Has anyone tried this yet? When I run the patch the ROM drops by half in size 16kb. I need it to go back to the 27C256 ROM which is 32kb. I’ve heard you can double them up with hex editor but this is the first time I’ve ran into this issue.


If you don’t want to fool with double up on the rom burner software (which will be a different procedure depending on the software) go into a dos window (cmd.exe) and just do a copy /b rom1.128 + rom1.128 rom1.256 and burn away.

If you don’t have windows this won’t help of course.

The game is only reading one half of the rom anyway, but doubling it up ensures that if the extra address pin a 256 has is floating for some reason it will return the same data regardless. If you were sure that pin were grounded (it’s A14, pin 27) you could just burn the 16k image into the bottom half of the 256 - we are talking about u26 of course which is supposed to be a 128 eprom, u27 should be a 256.


Thanks for the help the command line did the trick! I can’t wait to test


So if contest is not selected does it just play like the normal ROM? Just installed and curious what “factory” settings put it to.


The ambition is to have the tweaks of these mods menu adjustable. But for Rollergames, unfortunetly, this was not possible for the Sudden death and the individual lock accounting.

The contest game adjustment will, in addition to Williams letters, control the limited ball search and the mystery random/pattern (with no eb/special).


So just to clarify, if contest mode is on, you get the predicable mystery awards, but the locks don’t release end of game.

If contest mode is off, the mystery awards are random, but the locks clear at the end of the game?


End of game lock release is the Save locks adjustement.

The Contest game adjustment = yes will prevent locks released as per a ball search.

Predicted mystery awards (with no eb and special), yes.


So if I want best of both worlds, I need to turn on contest mode, then turn lock saves off?


Yes. Made it easy. Save locks off is now the default.


Is lock stealing enabled in a 2 player game?


Factory Rollergames has lock stealing with an only semi-working compensation lock lits for stolen locks. Plus carry locks game-to-game, if the Save locks adjustement = yes.

The mod has individual locks-made requirement. And 100% working compensation when your locks made are removed from the trough by other players.

It works by keeping the diverter closed, diverting locks made to the inlane. If the lock made is “already” in the lock trough. Due the efford of an opponent.
