Okay, can't figure out how to upload a text file.

Put it on your site, with a link, so we can just go get it.

Lee.

Okay, the 'commented file' is now on my website and there is a link to it for those that want to help in this endeavor.

Please don't laugh to much at the current set of comments that I put on it.

Also, I discovered that part of the reason that the machine has been freaking out is that the setting for number of balls and 'light reset option' was incorrect and caused it to do freaky things. It seems the program does not handle bad data very well.

Thanks again for everyone's help.

I may have found this bit but I don't know what to do about it yet, it's not clear what the code is trying to do.

Lee.

Anyone have any idea where to get the artwork file needed to run this in MAME?

Lee.

maybe fake it using another artowrk file for another game and renaming it?

It seems the artwork file(s) provide all the attributes of the virtual table. There may be an archive of the file(s) needed on vpforums.org but I can't be arsed joining yet another forum just to see if it is what I need.

wrkey you seem to have done this, what files do I need and where do I get them?

Lee.

The artwork seems to be packed up in a binary archive: I've sent you a link by pm. You might be able to get the raw files by joining the vpforums.org and contacting the author.

(I suspect wrkey downloaded the bundle and played the game, without needing to unpack. Again, you need to be on the forum to do that.)

Edit: linkify

I've patched the score bug and uploaded an archive of the images to here.

In simulation at least the behaviour now seems consistent for all four players.

Lee.

This should initiate the "special technique" for resetting the NVRAM.

Find a card edge and card socket that will fit J8, the audio port. Make a through connector.

Connect 330 ohm resistors between 0V on pin 10 and each of pins 8, 6, 4 and 1.

With this "special technique" adapter connected inline with the audio port and with the test/play/set switch in the set position switch on the machine.

All the options should be reset and you may need to set a few things like the price of a game and balls per game.

Switch off and remove the "special technique" adapter, the machine should now think it is factory fresh.

Lee.

Digging through the code it looks like the test and rotational tilt switches may have been swapped at sometime but not all off the code was updated to reflect this change.

Can you check and make sure that the test switch goes to J1 pin 3 and the rotational tilt switch goes to J1 pin 4 as per the schematic?

Lee.

Sorry for my absence, went to Washing DC with my kids on Spring break.

As for the PinMame images and such, I downloaded everything from the PinMame forum. It's actually quite involved to get it all down and installed and working. But once you got one table up and running, you can easily download others.

Lee! Thank you so much for your help. I will be pull you file and send it to the guys that work on PinMame and see how it flys. I don't have a way to burn a chip with the new code so I'll have to find someone here local that can do it for me and then I'll swap the chips out on my motherboard (retain the old and try the new).

As for the rotation tilt question, you may be right. I did manage to get the machine 'un hung' but now it's having trouble starting the game as it appears that it's always in tilt and the rotational Tilt adjustment light flashes on and off. I'll validate the pin settings and let you know what I find out.

As for resetting the machine, could I just unplug the battery for say 10 minutes and then put it back to reset the memory? To get to all the cards on this machine is quite a chore the ways it's made.

Thanks,

Rusty

Email I received from Gerrit after I delivered the code changes to him:

Confirmed, the game seems to work better now with Lee's change.
He only touched two bytes in the code anyway:

>fc /b nolabel_chkac10.bin spect_u4.dat
00000073: FF 7F
00000076: 80 00
000000B2: 81 01
00000174: 86 06
0000017E: 80 00
000002B0: A0 90 <--
000002B1: 03 05 <--

The above five changes were added by me
when merging both the U4 dumps we had.

The disassembled code changes from this:

0AAC: C0 03 cpy #$03
0AAE: B0 07 bcs $0AB7
0AB0: A0 03 ldy #$03 <-- doesn't make any sense at all!
0AB2: A0 E6 ldy #$E6
0AB4: 0A asl a
0AB5: 91 31 sta ($31),y
0AB7: A5 EE lda $EE
0AB9: 48 pha
0ABA: 20 2E 0B jsr $0B2E

to this:

0AAC: C0 03 cpy #$03
0AAE: B0 07 bcs $0AB7
0AB0: 90 05 bcc $0AB7 <-- doesn't make much sense!
0AB2: A0 E6 ldy #$E6
0AB4: 0A asl a
0AB5: 91 31 sta ($31),y
0AB7: A5 EE lda $EE
0AB9: 48 pha
0ABA: 20 2E 0B jsr $0B2E

Point is, if you do a "branch if carry set" first, and do
a "branch if carry clear" right behind it, you would probably
not want to jump to the same address!

So please ask Lee why he thinks this is correct!?

I offer another solution:

0AAC: C0 03 cpy #$03
0AAE: B0 07 bcs $0AB7
0AB0: 90 03 bcc $0AB5 <-- makes more sense
0AB2: A0 E6 ldy #$E6
0AB4: 0A asl a
0AB5: 91 31 sta ($31),y
0AB7: A5 EE lda $EE
0AB9: 48 pha
0ABA: 20 2E 0B jsr $0B2E

This will jump to different locations on carry set and carry clear,
and also doesn't sound the special and tilt sounds, or will award
a credit on each 1,000 made on player #2.

Seeing how the new differences are in an area that might have been badly
dumped before the merge, it's very clear to me now that the U4 we have
is still ill, and again I have to urge you to try and get a dump of
Gary's 2716 chip I told you about before!

We might never see the original behaviour of the game otherwise!

Perhaps this will shed some light on what I've done.



Cheers,
Lee.

I'll forward this information on to Gerrit.
