well, that was interesting. I did some additional tests and the sound bug is back. I can reproduce it when I play one credit and let the timer run out. When I start a new game after that, the sound bug is there from the start.
Conversion of single layer Taito Cup Finals PCB to something else?

Yep that's the one. 
Wow, totally missed this thread! Great work! I remember writing about F3 PCB eons ago, lol: http://therealundamned.blogspot.com/2009/08/taito-f3-pcb-101.html
I think my article is missing a couple games, actually.
If anyone is looking for a donor PCB, I have a Ring Rage and Taito Cup Final in my sales thread: FS: Lots of PCBs & Carts!

did some more testing. Mame behaves exactly the same. Corrupted sound when you start the second game.
As an additional test I put all the eproms on a rom board. There I had no sound issues when running the game.

Interesting, so what does the rom board do differently?

Confirmed here!
Finally got a working one to test this convert, the usual story (not enough roms to finish the job) but good enough for audio test.
This is not a PLD issue, more like some missing line(s) on the soundcpu side.
Tested with the RAS line mod i posted, it changes the behavior but does not fix the problem.
FWIW this is one of the most complex sound hardware on any pcb. The other board here with no sound still unknown why.
In this video the credit noise actually works but normally it won't after game over, speeches are missing and it eventually crashes out.

A shame but I am glad it's not just me, do you think it effects all games or just rayforce?

Yeah i'm sure the standard older games will work:
That's like riding fight, arabian magic, top rank stars etc also on single layer.
Not the best games but worth a shot.
The newer games clearly boot (with modded pal's) but i'm sure they will have sound glitches due to the board layout.
Some bad news though.... when you run anything other than cupfinal on the cupfinal board.... cupfinal roms won't run again due to security bits wiped!!

It's a pain in the arse for testing reasons!
"Some bad news though.... when you run anything other than cupfinal on the cupfinal board.... cupfinal roms won't run again due to security bits wiped!!"
this happens because the pcb does not initialize the eeprom.
if you flash it externally, cupfinal will work again

I'm having the same problem with it, i converted one to Gekirindan and the sound dies after 3-4 minutes in-game, complitely random, sometimes sooner and sometimes later in the second stage.
The second one, Elevator Action Returns, did not have sound at all after the conversion and it was working fine with cupfinals.

Found this vid from 2 years ago:
So grid seeker works, but needs canned eprom data and 1 mask rom fixing.
Looks like he's done something on the PLD's also.

Is this with the handcrafted PAL that apparently works for @mypinball?
Yeah, apparently. He didn't even reply once after my payment, or gently answering some questions. It's fine, the answer should probably be "Mine works perfectly, its your fault" so i give the answer by myself. Thats how usually these things goes, it's never the producer fault.

This one seems to work fine
Needs tile rom and sound rom rework after this seems perfect!
Basically in mame you are looking for SOUND: // V1
Anything with sound //V2 will have issues it needs the D53 upper pal.

Ok so whilst looking at the sound section on this (dead sound) cup final, i came across this massive amount of information regarding the 5510 / ensoniq keyboard the sound section is ripped from.
It's 100's of pages and page 1 is an example of the info that follows. It's not all relevant but the schematics, fault finding etc should all transport over :

After reading this, i think the fault on my board is the 68681.

Good morning all,
Just a note, it is not necessary to buy a Gal, it is enough to reprogram the existing Pal by deleting it and writing the new code the PALCE20V8, for my part I use the PLD D66-09 from "Ray Force -Gunlock Rom Board"
Good game
