No orbit shot possible with left flipper...you can bank off of O target and pass to right of ball lock up there and ball will travel as with plunger shot along wireform and thru a 1way gate into upper lanes. A 1way gate above left upper checkout halts ball from completing an orbit and only allows for the right flipper shot thru the left orbit and over the wire form at upper right, opening that gate to score the orbit. If you hit it during the 10 second countdown after completing any 3 bank it carrys bonus point progress to next ball and rings a loud bell in cabinet. If I had to find something to knock FPII down for it is that you cant make that shot clean off left flipper to the upper right and into the lanes. You can bang the left orbit and fall short into them sometimes, or thru the pops, but the only sure way is to lock a ball so you can send the next plunger shot up there.
My FP2 has the added speech card and Firepower speech roms which it does use. The left ramp is challenging but very makeable. When set up correctly this game is bad ass. Have played Firepower plenty, and love it, but as great a game as it is, the speed flow and shot choices on FPII beat it easily, no contest. 2 of FP1's ball locks on FPII fly around the table and back at the flippers. Multiball is much harder to achieve on FP1, very rewarding but drains so fast usually. Multiball on FPII is much easier, but the shot straight thru the pops is tough, it gives that upper target more purpose and when you hit it you can keep multiball going for awhile sometimes. Too fun.

The software for FPII has speech callouts in the code, if a bit limited. Maybe the original FP code was used for it and they were left in. So I just added this speech board with FP roms from here...

My FPII sound board had the 40 pin IDE interconnect as it was replaced at some point, so it only cost $60 and shipping to add the speech. I think the original sound board did not have the 40 pin, so if that is the case you can purchase the sound/speech boards on same page linked above. Works great, once you get the jumpers and dip switches and volume set correctly.

One drawback is that FPII has some great sounds that occassional get cut off short by the speech. When I first put the speech in I noticed it right away, but at this point I forget specifically when it happens. But hey, it talks which is cool.

The 4 ABCD lanes at the top of the playfield can be cycled with the right flipper button. So if you have 'A' lit than each time you hit the right flipper it moves the lit lane to the right, A-B-C-D-A-B-C-D ect. so you are trying to move the lit lanes out of the way of the ball. Each time you lite all 4 lanes it advances the bonus multiplier.

It is a very tight shot to make but it can be done...what I meant is that the right lane really is not an orbit as it does not roll all the way around and back down toward the flippers because of the one way gate.
