Quoted from DavidPinballWizz:
Is the new code for the Escape Wizard mode that you can start when you want (hit both flippers before you press start) also the actual wizard mode for completing the game?
Currently Escape Nublar isn't coded at all.
Once you get to, and play, Visitor Centre there are no more dinosaurs to capture and that portion of the game is effectively a dead end.
It still leaves the control room modes to play, which leads to Secure Control Room mini wizard.
As well as the T-rex/Truck modes, which leads to Museum Mayhem (The BEST mode ever). After Museum Mayhem, EVERY T-Rex mode will be the multiball and you can't play the other modes again.
There's still Pteradon attack, from the right ramp, and DNA combos to go for.
Once latest code is released, which can't be far away seeing as it has gone to a couple of locations to be Beta tested, Escape Nublar will be playable either by getting passed Visitor Centre, or by using the flipper code at the start of the game.
IMHO JP has got to be the greatest game ever released from a playfield layout perspective, integration of theming, graphics, sound and coding. I thought IMdn was good, but JP is just different level awesome.
