On completing ...

When Dinosaurs Ruled the Earth

Secret super-wizard “epilogue” mode awarded for successfully completing Visitor’s Center, Museum Mayhem, Secure Control Room, and Escape Nublar. Timed 6-ball 60-second multiball with unlimited ball save similar to Cherry Bomb in GOTG. All Amber features are running (scoring 1/2 your Amber value) and all shots are lit for jackpots of roughly 1.5x your Amber value. When time runs out, all balls are drained and your game ends.

I'm picking up a used JP Pro later today. Other than chipping/pooling around a few posts, which I am 100% aware of and okay with, is there anything else I should be looking for in one of these? Thanks!

Check if any posts are loose and if any coil stops are broken.

Thanks! Coil stops shouldn't wear out after 6 months, but can be easily replaced. I'll keep it in mind.

There have been plenty of reports by JP owners of faulty and broken coil stops. Easy and cheap replacement but still worth a look.

I’ve spent a lot of time trying to get that shot dialed in. People here seem to accept it in it’s clunkyness. It’s by far the worst part of tjis game, seems like the ball should go to the upper flipper with a clean shot but it doesn’t.

Took me a little time, but I got mine as smooth as butter. I originally figured it was not curving far enough around into the orbit, so I bent my left ball guide in as far as I could without trapping the ball against the other side. Unfortunately, that ended up making it worse. I then bent it back and using high speed mode on my phone camera, I realized that the ball was actually making the turn too hard and hitting the right ball guide enough to send it bouncing into the orbit guide. So I had to reverse my thinking and actually bend the left ball guide a bit the the left / straighten it out slightly. Now 90% of all shots smoothly orbit, while only the sloppiest ones will still slow down enough to drop in the pops. I believe this is as intended. It took some messing around, but it was definitely well worth it to have that awesome shot nice and smooth!

I was adjusting my 3rd flipper yesterday because the left upper shots seemed way too hard to make. Once I did that, the shots were so much easier to make so that's definitely something that should be taken into account.

Also, I was surprised to see that there were 3x posts that were very loose.. the one right next to the 3rd flipper, and the 2x at the right ramp so I tightened them.

Without going back on this whole thread, is this a common issue with people's JPs? Also, a random small black screw popped out and was on the playfield, but I couldn't locate where it came from lol

The small black screw likely belongs to your TRex bottom jaw

Loose posts are unfortunately a common Stern issue lately. I had many loose in JP and GOTG. BK had literally every post loose...some barely finger tight. Had that entire game apart tightening things down.

What position did you set your 3rd flipper at? Could you post a pic? Thanks.

This position works great

Ok, then I know it's not just me who has the problem. I will try to find a solution. I will post it here then.

Thanks man! Just took it apart. You were right.

Now, to find the other screw.. unless Stern forgot it.

Great! Happy to help. Hope you can find the other screw!

Does the post stick out enough still to deflect the ball to the left slingshot area?

Yeah I adjusted it so it actually feeds the left flipper vs hitting the slingshot - it works great !

I need to tweak mine then. It goes STDM most of the time so I always have to either flip or hold the flipper up and hope for a safe return!

With all this talk about tweaking posts/flippers etc, I’ve been having a problem for a while now shooting the right orbit, the ball used to exit cleanly to the upper flipper, now it clips the truck newton ball. The playfield angle hasn’t changed sitting around 6.5-7deg. Any ideas? Possibly the ball guide shifted?

I’m so giddy to get this game I could just explode! Hopefully only another 10 days or so!

Anyone have issues with the download of new code on premium? Downloaded, extracted the folder, moved 2 files to root if SD. Game acted like it wasn't there.

Is your card formatted for FAT32?

Claimed

Anyone know when Stern will be making more lit Amber shooter rods? I can't find one anywhere and want one. Hopefully they are planning on another run.

I added a bunch of trees to my LE. I know some might think is silly but I like the idea of trying to make the PF more of a jungle. It was only $10 on amazon and a ilttle double sticky tape. Anyone others having trouble with their raptor gate not going down all the way?

Yep. Same card I always use too. I tried reformatting as well.

Mine too. For the first few months I could right orbit x2 combo almost every time by holding the upper flipper as it came around. Now it hits the truck Newton ball more often than not. I’ve tried moving the guide a bit but have quite been able to get it back dialed in the way it started. Would love to hear some ideas but I’m not sure it can be anything but the guide and pitch, right?

Thanks for sharing. I used these settings on my Premium and it sounds way better.

Does anyone know if you can still but the amber shooter rod and housing mod. Looks like they are sold out everywhere. Thanks.

I’ve dealt with a couple raptor gate issues:

- (minor) There is a vertical adjustment on the mech. Lift the PF and it should be obvious (2 screws that lift/lower).
- If the gate is too close to an edge (i.e. isn’t centered properly), the gate can get caught on the PF. Hope this isn’t what’s happening to yours.

FWIW, trees are silly, but it’s your game and it should make you happy!

Of course he gonna do what makes him happy!

Coming soon. Next few weeks. Per Stern.

Try using a different usb stick, sometimes games just don't recognize certain ones sometimes.

Make sure to use the USB ports that are facing out, not the top one. Also make sure that you have the machine turned off, insert the flash drive, and turn on with it in one of the front ports. My best success is with FAT32 formatted drives, 4GB or smaller (though you'll need at least 4GB for JP).

Awesome ! I'm just glad Stern included the ability to adjust and fine tune the sound. Definitely makes a big difference.

This is probably going to sound a little off-the-wall.

I have a JP Pro.

I would like to animate the existing T-Rex head, using powered logic with an Arduino zero or other, to activate off of the switch that reads the ball going up the t-rex scoop. I would like to add a motor or two (one for head, one for jaws) and a light, that would fire on the switch sense.

Has someone done this already? I understand there would be modifications needed with the T-Rex head.

Was able to pick up a used Jurassic Park Pro last night from a local pinsider. $5,200 for one with less than 100 plays, speaker lights, and a shaker.

I'm a huge fan of side blades and will probably drop some in, along with a raptor toy and new helicopter. This game is deeper than I will ever get through and will keep me very busy until my Rick and Morty shows up.

Any other highly recommended mods on this one?

High Speed (Sold) goes this week to get access to the door back.

enjoy JP, it is amazing.

What is that ball in the floor?

That is a Paw Patrol ball. My Arcade takes up 1/3 of the basement playroom.

No one yet, to my knowledge, has produced an animated Trex head for the Pro.
A Mod that would likely sell well...if you wish to try.

it looks like a crystal ball or something laying there. I feel ya man, my son had some friends over last night and they all brought their gaming PCs and VR equipment over. I could not even squeeze in some pinball time.

I just finished making a video tutorial that details how to fix the manual and auto plunge issue for the shooter lane. I hope this helps anyone having ball reject issues in the u-turn.

Great vid!
What size washers?
Thx!

I'm now a proud owner of a Premium JP. Game was HUO and less than 150 games, shaker, HD glass, and Art Blades installed. Put about 15 games on it yesterday and really impressed, that T Rex has to be one of the coolest toys ever! Love the game and can't wait to play some more later this evening.

20200222_132338 (resized).jpg

Crazy some of these low play HUO's... How can you only put 150 on a JP...I did that in a couple days!

Not super crazy! I just unloaded my PRO to upgrade to a Premium.

But this was a Premium

The Modfather sells the trees for 29.99 for a set of 4 trees. $10.99 for 15/20 trees is a pretty good deal.
I did the same to add to the jungle feel but got the same trees as the Modfather sells as I like them and did different placements.

The nylon washer needs to be 3/8 of an inch in diameter. (Not a 3/8 inch washer).
