Not much, have seen at least 2 types (Rev.2 & Rev.3), which I think are interchangeable (some pics attached, including some info from 8035 System manual). Wiring diagram for UN in manual appears to indicate the speaker gets feed from Output card pin1, via 250ohm volume pot and other terminal is connected to Power plug Pos.10 (-9v).

Do we have any roms or docs ? Thanks Paul, do you know anything more about the output card ?

Hi Pete, Ultimate Nudge sound is, I believe, generated from an Output card within the main 8035 System cage (at position 0 - manual lists speaker connection at pin1). There is an option to inhibit coin alarms via Option Switch 4 and attract mode via Option Switch 3, but no option to kill sound completely - only adjustable via a pot inside machine.

This is awesome:) I really hope to see MPU1 in the future at this rate.

at the moment you just load in the rom zip and it recognizes them and creates a basic layout in javascript. I am hoping to create a mini emulator with just the non MFME techs and some basic design tools soon. The roms for these games are all on here, i can attach them to this thread if you like ?

Many thanks. Is there anyway to download and separate the roms and layouts in case, for example I'm missing the rom files?

Hi all I've just got my bell fruit bar 7s back working with help from a few people on here and now need an alphanumeric display if anyone has got a spare and a working coin mech as the one in the cab must have broke off from it's bracket as it was in two bits at the bottom of the cab. Here's a couple of pics of the display and coin mech. If anyone has one or both for sale that would be great. Cheers Brian

Great work Pete, superb to see this tech running!

Good luck Pete with the emulator!

I am looking to improve my Summit Coin emulation. I have everything i could find on this site. Ultimate Nudge is working the best of them so far I particularly need information on any Sound Boards used. Play Ultimate Nudge Play Nudge Accumulator Play Supershot (Dutch) Play Push Over (Video Fruit) These are in various states of emulation so if you can help with anything that would be awesome

Great stuff, Jane!

Your thought that it may be a different piece of code is correct. When it's letting you off a mistake on unlimited nudges, it looks at the reels in order (4, 1, 2, 3) and, if the reel it's currently examining is not displaying a triple bar, it nudges it up until it is. This has the strange result that it nudges a reel up 23 times instead of once down if the triple bar is immediately above the winline when it starts. It also means that it nudges straight through the cherry. The usual GAIN code is not invoked at all. I think I tried to demonstrate this at the end of my recent YT video entitled "Four-reeled extravaganza...". You raise a very important point though. Changing one thing may indeed have unintended consequences elsewhere! 🤪

Good for you! It's not easy and requires a lot of time and effort. They'd certainly not be far wrong if they calculated that there would be hardly any people with the determination to persist!

Here is my STOP THE CLOCK modded roms 1: all cash 3 pounds 2: nudge block uncapped to 12 nudges on random stop 3: character and checksum removed (so you can make a spare card like i did) MOD 7B - CHARACTER REMOVED - TO BURN TO EPROMS.zip

Yes i would love to have met someone who programmed them. My son designs games for children online and he has a programmer that makes the software. I am pretty sure i was told 20 years ago that the same guy that designed both SMASH AND GRAB and BIG SHOT moved to the states. There was also easter eggs programmed into alot of these so the programmers would go around the country if they lost their jobs and canned them. I think i heard an ACE prgrammer got caught out. Would have loved to have been about then. I was only 14 when sag came out , i was in the industry but was told i would never learn how to break into these programs. I said "HOLD MY BEER"

Looks like they send pulses to a sound board that has its own software eprom on it

Does anyone know about the sound boards used in these ? I have them all running but struggling with the sound

I also found Supershot buried deep in a thread here lol Supershot PROM.zip

Awesome, will see if I can get them running

Its sounds good bernard but if you remove the gain code then what would happen on unlimited nudges 🤔. Id hate to fluff the jackpot and then think it doesn't matter as gain will nudge the bars in but, without the gain obviously this isnt possible unless its a different bit of code for the unlimited nudge gain .
