Joined the club with heavily modified premium a few weeks ago. One of the mods is Lior’s sculpted t rex head. I’d say he only catches the ball 20-30% of the time. Are there any suggested tweaks to help increase this percentage? I already searched inside the thread and found a few others asking the same question but didn’t seem to find a fix. Highly appreciated if someone can point me in the right direction.

Thanks for helping on this crazy-good game!

There’s a dedicated thread for the trex head with a lot of info, take a look and ask more questions there if needed

Graphic EQ Settings Help Sought:

Just installed a pair of Kenwood 1366 5.25” backbox speakers and wondered if those of you out there with them have learned how to optimize the settings in the ten-band EQ.
Has anyone discovered that the high/low-shelf setting actually makes these Kenwoods sound better than the EQ setting?
The curious thing is that they sound better set to 8 ohm when they are in fact 4 ohm.
I also loaded in this DIY cab speaker upgrade, with guidance from other Pinside threads.

Do you have a link? Can’t seem to find it. My daughter painted mine and doesn’t catch the pinball all the time either.

Maybe it’s an amplifier issue. Factory speakers are 8ohm. Those require less power. Selecting 4Ω might overdrive the amp (not providing enough power to the speaker) and muddy the sound. Pinwoofer provides a new and matched amplifier for these reasons.

Unless I'm mistaken, I think prentice is referring to the dedicated thread for Lior's / Art Of Pinball T-Rex head owners: https://pinside.com/pinball/forum/topic/stern-jurassic-park-sculpted-mods-by-the-art-of-pinball

BallyKISS1978 You are having issues after your stock head mold (NOT Lior's custom one) was removed, painted and replaced correct? If so, you would NOT want to post in that above thread. If you started having catching issues after re-installing the head but she was catching balls before, you probably (inadvertently) messed something up during re-mounting of the assembly, head/jaw mold, or something got tweaked in the assembly during the process. There is no one-all-"this is what you need to do" solution unfortunately. The head assembly itself is very temperamental mechanically and mounting-wise and very much individually game dependent when it comes to placement + software settings + optics in play to make the T-Rex reliably catch balls. There are a few other threads about similar T-Rex issues but to link those to ya would likely take you down the wrong rabbit hole. Search around in the forums, look at key posts in this one, etc. and see if anyone's posts / videos, etc. seem to match your current head's catching issue. This guide put out by Stern and now on Marcos might help you as well: https://www.marcospecialties.com/pinball-parts-blog/wp-content/uploads/2021/03/JURASSIC_PARK_TREX_ALIGNMENT_PROCEDURE.pdf

Thank you so much timlah79. Really appreciate your help. Have a good rest of your weekend and have a good upcoming thanksgiving!

Correct. You may be overdriving the amp regardless of what your speakers Ohms say they are. I have an original run JP LE, with default speakers and back then the software was defaulted to 4 Ohms. Sounded super dull and would require bumping the game volume up but still sounding very boomy and dull at the 4 Ohms setting. Turn the volume down quite a bit and setting it to 8 Ohms = clarity and no need to bump the internal amplifier. I don't have experience installing different speakers but I know my ears. If 8 Ohms sounds good, set the software to that. Also, you shouldn't need to tweak the EQ much. High/Low shelf is good for internal speakers + internal SUB from my testing but I have my JP audio outputted to an outboard mixer + outboard SUB via a mod. I put a lot of info in this topic I created a long time ago if you want to check it out: https://pinside.com/pinball/forum/topic/how-i-set-up-the-perfect-audio-experience-for-my-small-gameroom

In summary, if the 8 Ohms setting sounds better than 4 Ohms with your new speakers, keep it that way. I don't think you're damaging anything by doing so. Toy with the EQ settings if things seem off balance but I prefer to keep my JP settings flat aka no EQ, no High/Low shelf.

Thanks, Tim.
Very helpful.
I’ll read your thread.

Thanks, Balderdash.
I don’t doubt I could benefit from an upgraded amp.
I may get around to investing in one eventually.
These upgraded speakers do sound better, but they need more power to drive them, so suddenly I’m setting my pin’s volume to 30 rather than 15.

Does anyone knows how many Jurassic Park have been made?

Lots!

Stern do not release their numbers.

Anyone have movie code and insider connect working on their JP? Not sure if my movie code works with it since it says 1.03. I want to upgrade to IC but don’t want to lose custom code

Anyone needs a stern JP topper
Message me

You have to ditch the movie code if you want to use Insider Connected.

No you dont. 1.05 works with IC

I'm curious how this is going to work out.

My movie code is 1.03... whats different? I got from originator and "donated"....

Pretty sure it just adds the IC support

Interesting, could've sworn the person that made the code thought you had to use stock code to use IC. Was he mistaken?

He added his custom stuff to the base Stern 1.05

Below is what Stern introduced in 1.05, 1.06 and 1.07 (on the Prem) - there were no gameplay changes, although there were a few code fixes and setting changes (eg DNA extra ball now defaults to 6 DNA's - previously it was 8, but you can simply change this in your settings manually). Predominantly the updates are associated with Topper and IC

V1.07.0 - September 12th, 2022
==============================
- System - Updated to V3.22.0 on OS: V2.7.0

- Corrected potential game reset issue.

- When entering a WiFi password, the previous characters will be displayed as an asterisk.
The WiFi password will be displayed as all asterisk when entering the setup screens or scanning
the WiFi setup QR code.

- Added Service Menu Tech Alert when weak signal strength is detected. The signal strength
and SSID will be displayed. An average signal strength < 40 is considered weak. A weak
WiFi signal may contribute to a slower or inconsistent connection which may effect the abilty
to login or download software updates. Signal strength can be improved by the use of an
inexpensive WiFi extender. A wired Ethernet connection can also be used in cases where WiFi
signals are problematic.

- Added Standard Adjustment "ENABLE HOME TEAM IN COINPLAY", default value of NO.
Setting this to YES will allow Insider Home Team to be available for machines not
set to Free Play. Normally "USE INSIDER HOME TEAM" is only available in Free Play
mode. Many home players, who choose to use their game in Coin Play, have requested
the ability to enjoy Home Team! Setting this this adjustment to YES will default the Home
Team Guest Retention to Never. If you wish a different setting you will have update that
adjustment after enabling Home Team in CoinPlay. Home Team is not available for machines
registered to a Pro account operating in a commercial environment.

- Added Standard Adjustment "REMOVE FRACTIONAL CREDITS". Values are:
"NEVER" and "AFTER X MINUTES IDLE", where X is between 30 and 240.
The default value is "NEVER". If the game is idle (no coin or flipper
switch activity in attract mode) for X minutes, any fractional credits will
be removed. Whole credits will NOT be removed.

- Added Standard Audit "FRACTIONAL CREDITS REMOVED", which will track the number of
fractional credits that have been removed when the game was idle.

- Changed the default value for Insider Connected Software Update to "Install updates automatically".

V1.06.0 - July 29th, 2022
=========================
- Insider Connected - Home Team

The Home Team features allows Insider Connected players to log in
and play without scanning their QR code.
When the game is registered to a home location and set to Free Play,
Home Team can be enabled via Standard Adjust #51 or from Guided Setup.
Up to 8 players can be added to the Home Team from the Stern Insider
Connected Setup menu.

The Home Team can be shared across all games registered at the game's
location by enabling the Home Team Standard Adjustment on each game.
Players need only be added once to the Home Team. Players can be
later removed from the Home Team, and guests can be temporarily
added to the Home Team.

Find out more about Home Team at http://insider.sternpinball.com.

Right Wireform Return: Ball Bounce at the Ball Drop, Anyone?

An auto-launched ball (or a smartly struck shot to the Helipad) on my JP2 PRO will come to the end of the wireform, directly above the ball drop, and "bounce" off the terminus and back up the wireform six inches or so and then roll back and finally down into the ball drop. This is uncommon, yes? My game is set to 6.7-degrees pitch. This bounce effect doesn't change with variations in pitch or lateral leveling. I would like to adjust this out if I can. I have made zero changes to the geometry of this ramp or the points where it's secured to the playfield.

Nope, that’s not great. I would be taking the wireform off and slightly bending the upper curved section where the ball strikes so that it is above its current height. That will change the forces on impact and should send it it downwards.

Hi, Had.
Thanks for your input. Your solution did occur to me, but I worried about causing the chrome to flake if I bent any part of the wireform.

Pretty sure the wireforms are just stainless steel?

How does the custom 1.03 work on 1.05? Do you install stern 1.05 in order to activate IC then remove SD and go back to 1.03 to have IC work?

No. He came out with a 1.05 ver of his code. You run that and IC works.

I think you should cover your tools or the wireform with fabric to avoid damage

Has anyone done any artwork replacement for the center apron decal? I usually like to swap out the seizure warning stickers for something more artistic and less CYA...

There's these magnetic aprons - both IC and non-IC versions https://www.wizardmod.com/jurassic-park-pinball-mods

Thanks. I'm having the apron PC'd so I don't want to cover it. I'm just looking for something fun for the center apron. I might have to mock something up myself. Maybe something simple like the JP logo.

Agreed. Primarily trying to reassure that from the factory there’s not a chrome coating that’s going to pop off when bent.

I’ve seen some decals for the apron center that describe the function(s) of the action button. I find that a smart use of the space.

In this thread?

I cant remember where I saw it but it was in the last week. It may have been in the stern SW thread. If I can find it I’ll link it here.

Edit: It was actually the standard Stern centre sticker. Could be reworked without the seizure warning. I would cover the colors and what they mean such as “hold button to add a ball when flashing yellow.”

https://pinside.com/pinball/forum/topic/stern-star-wars-clubmay-the-force-be-with-you/page/263#post-7245841

You could crop this...

I make/sell magnetic decals for Premium/LE (metal aprons) that cover the OEM center decal. I could also do a vinyl decal for Pro (plastic apron).

I would be interested in a pro version.

PM'd you.

Made these flipper mods. Would suit JP. Comes in red or green.

Hello.

I just joined the club with a JP Pro the other day and I was hoping to get my game updated to the Ultimate code with the actual assets. I could care less about the insider connected platform, which I know it doesn't support the new features from that.

Can someone provide me a link with where to download this from?

Thanks.

Yeah that's a good idea. Despite having played it for a bit, I still find the Smart Missile animation so dense/poorly laid out (and briefly displayed) that most of the time I cannot even see what reward I'm selecting before I need to shoot.

The challenge is that it varies depending upon where you're at in the game but maybe you could come up with something (just need to keep it relatively simple)

• Choice 1
o If Chaos Multiball is active or lit - Super Supply Drop - Awards the next item in the Super Supply Drop sequence.
o Otherwise - Complete CHAOS - Awards five CHAOS letters, wrapping back to where your current lit letter was if spelling CHAOS doesn’t light the MB. This does not necessarily immediately start Chaos MB if it lights it; the ball still has to hit the target again.

• Choice 2
o If you’re in a Paddock - Clear Paddock - captures the current dino and collects all remaining rescues for the paddock, adding them to both your rescue total and rescue streak.
o Otherwise - Super Combos - Combos score 5x for the remainder of the ball.

• Choices 3 and 4 - Two different awards from the following options, with the last two not available until some of the earlier options have been collected:
o Rescues - +5 Rescues at first; collecting it can add +10 Rescues to the award pool. May not be a bad first option if you’re good at the Smart Missile shot, considering the +5 automatically relights it.
o Raptor Multiball - Immediately starts Raptor Tri-Ball. This also counts as having gone through the regular sequence of lighting it, meaning you’ll start over at the next difficulty for the next RTB.
o Extra Ball - Immediately awards an extra ball.
o Fossil - Spots a “wildcard” Fossil.
o Super Escape - For the remainder of the ball, “Lite Escape” no longer needs to be qualified using the pops switch (ie, “Lite Escape” will always be flashing if “Escape” is not lit.)

• Choice 5 -
o During any Multiball and / or mode (Control Room / T-Rex), or after Invalid?? was earned - 25 Million - I dunno…
o Otherwise - Invalid?? - Starts Invalid Frenzy immediately, without having to qualify and play all four Control Room modes. Scoring is the same as in the normal Invalid Frenzy and you can still enter your initials by getting a high enough score during this mode. Invalid Frenzy can only be chosen once per game; afterwards, Choice 5 becomes 25 million. This option is disabled during competitive play. If Chaos Multiball is lit at the target, you can stack the two with a successful shot. You can still play a second Invalid Frenzy through the traditional path of lighting it.

• Choice 6 - Abort - selecting this award will deactivate the Smart Missile and the inlane insert will flash instead of being lit solid; you can requalify it (lit solid again) with two shots to the Truck.

Ah, thanks for this context! I haven’t studied these rules yet.

I just get used to how many times I need to tap the action button

First time I tend to go for +5 rescues (2 taps on the action button) and this also relights smart missile. If I'm in a paddock, I'll go for Clear Paddock (1 tap); otherwise if I've already collected the +5 rescues, then I'll go for Extra Ball (3 taps).

Invalid can be a bit of fun, I've never stacked it with Chaos MB - now that would be a real blast!!

If trying to get to the 2nd Chaos MB, Complete Chaos (no taps) would definitely help and you also get access to a Control Room event when you've spelt CHAOS twice. Just depends on what you're going for and your game strategy
