Text below is copied from the patch file readme. I've got mine set up so that there is a delay before jackpot is available otherwise using tourney ROM as is. I am considering switching to having to hit all of the targets before jackpot is available as I still find it too easy to get. I'd probably raise jackpot to start at a million then.
TOURNAMENT ROMSET DIFFERENCES
========== ====== ===========
The tournament romset seeks to address these points:
All auto percentaging difficulty adjustments have been eliminated.
The drain plug timer will still 'ramp up' as a player accumulates
more and more millions of points however, as stock.
The ability to collect the percentaged extra ball from A-B lanes
has been eliminated.
The ability to earn an extra ball (via the drop bank) now has an
adjustment setting, on/off. If set to off, a variable amount of
points selectable by the tournament director can be awarded when
collecting an extra ball, or none at all.
The top saucer score advanced via each A-B completion has been been
reduced from 500k to 150k. This reduces the strategy of maxing the
saucer and repeatedly shooting it (a very safe shot to the top).
The jackpot will now start and build for each player during the
game, and will advance as before with completed lock
qualifications, as well as via various targets around the
playfield and for selected combo (quick shot) shots.
The minimum and maximum jackpots are now included in the new
adjustment settings, and can be set to any range 0-9.9 million. If
the minimum and maximum are set the same, each player will get the
same jackpot value.
The bonus X saucer now has a setting to disable lock spots. If set
to off, no standup lock target qualifying will occur on saucer
shots. If set to on, it will spot a flashing standup lock target
the same way the stock rom does, left-right-center. As with the
stock rom, the center saucer will no longer spot targets after the
first multiball has been acheived.
The left loop (jackpot shot) now has an adjustment to turn off
qualifying an entire lock via the quick shot inlane. Players
skilled at this shot could have multiball qualified in as little as
3 shots.
Each of the timed features in the game (spinner, drop bank, left
loop, drain plug) now have the ability via a menu adjustment to
have their timers tweaked. Set the timer option to 'custom' to
unlock the individual settings of each feature. Values you enter
will 'stick' if you set back to a preset option for casual play the
next time you enter custom, so if you need to change your machine
setup for location/home play, you will not lose your tournament
timer settings.
Additionally, the drain plug can be disabled entirerly via a new
adjustment specifically for this purpose, and the time the drain
plug is up from the top popper is fixed.
Completion of the A-B lanes while the drop bank target timer is
active will add a small amount of time to this timer (only) to
allow a ball to return to the flippers for possible completion of
the drop bank.
Hitting the spinner while its timer is active will add a short
amount of time to the spinner timer.
All combo shots that advance jackpot are started when the ball
travels through an inlane. A short time is availble to do a
'quickshot' to either hold bonus lane, the bonus X saucer, and ????
(hidden 4 way combo). Many 10k point targets will also add to the
jackpot value. The jackpot value does NOT reset on collection.
Only one jackpot per multiball can be collected.
Finally, there are 2 new options relating to collecting the
jackpot: A time delay, where the jackpot collect will not be lit
until all 3 balls have exited the submarine ("JACKPOT IS LIT" on
display), and a skillful based lighting of the jackpot requiring
all 9 lock targets to be made in multiball before the jackpot is
lit ("FINISH ALL 123 LIGHTS JACKPOT" on display). As with stock
there is a grace period timer after multiball ends to collect a lit
jackpot, but you must have the jackpot lit to do so (you cannot
complete the 9 qualify targets during the grace period).
