Just joined the club this weekend!

Initially it had an issue with the test car switch #40, one of the wires was broken off. Resoldered it but the switch is way out of adjustment and is always closed. I was able to get it playable by loosening the left side of the car bracket and wedging in a thin piece of plastic from some clamshell packaging.

Is there a trick to accessing the adjustment screws? I see the two holes on the side but it doesn't look like there's enough room to get a terminal screwdriver in there.

Also, my game code is out of date - the problem above prevented the modes from starting. I have a bunch of EPROMs on hand from making game cartridges, it seems CPU is a 27C010 and Display is a 27C040. Can anyone confirm?

Thanks, but I need to know the actual chips they used. Worst case scenario I have to remove the stickers on mine to see the chip manufacturer's part #.

I peeled back the stickers on my CPU and Display ROMs enough to read the part numbers and their speeds. Figure I'd post it here for the next time someone googles Stern WhiteStar EPROM part numbers.

CPU: 27C1001 (aka 27C010) 100ns
Display: 27C4001 (aka 27C040) 80ns

Does anybody know if there's a way to manually adjust the number of hauler miles required to light extra ball?

It's auto-adjusted up to 1500 but I haven't found a setting to adjust it back down to the default 550.

I've also figured out how to hack the graphics ROM to replace text. So far I've altered the random scanner rewards (ex: Harvik Jacket -> 24 oz Bud can) and super fan mode:

Have any resources for doing this? Would like to make a set as well.

How to get multiball with only 1 lock shot:
1) Shoot the ramp and lock the 1st ball
2) Hold left flipper when plunging the 2nd ball to get the "good thinking!" lock
3) Do not plunge the 3rd ball, wait for ball search to launch it. The ball will exit the track via pit road, giving you an "I'd rather be lucky than good" lock, starting multiball.

Nice machine! I don't think the sound ROMs changed between versions so you may only need CPU and graphics ROMs. They're easy to swap, just be careful!

Marco sells the protector for the left ramp right side to match the factory left-left, I think it was $7. Forget about getting OEM right ramp protectors.

NASCAR is pretty good game when it's functioning correctly, the flow is great and stacking modes with multiball is a blast. The garage should shoot to the left flipper... recently played one at a show that kicked it to the right flipper for some reason

Agreed on not trying to color match the inserts - though I like green for the jackpot inserts, looks way better than yellow.

Had to pull the garage assembly to fix the test car switch, now I'm trying to get the test car dialed back in and locktited down. So frustrating when you think it's OK, then a dead center hit doesn't register.

I noticed the car attaches to the garage with two different nuts, one has a raised bushing that fits the hole in the bracket. Should they both be the same? I found it worked better with the bushing nut on the right side.

That's what I figured... I'll have to look out for another one.

The side with the normal nut slides a little bit allowing for more rotation, but for the most part it's pushed back.

30-50M, highest is 368M. I turned down the extra ball setting after that one.

There are some stacks that are worth big points, like Victory Laps + Multiball.

Just worry about getting to Champion Challenge and it will fall into place. Hold the flipper button at the beginning of the game to see which modes will award a champ letter, then focus on completing those.

Scoring does not grow exponentially in this game so it takes a bit of strategy to get big points.

Regular nut + blue locktite will get the job done. I'm missing the correct pivot nut as well.

For anyone who wants to do things wrong, zip ties also work.
