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

Hi Guys, it's been a while. Nothing new to add to the topic, but a few of you might be interested in a new venture I've taken on. https://frankbirdauthor.uk/ You can find a link to my novel!

Nifty Fifty (MPU4) – Solid Silver minimum £1 mod I have a Barcrest Nifty Fifty (checksum-removed) ROM. The Solid Silver feature (triggered by three 50p symbols) used to be able to award 50p. I wanted the minimum award to be £1 while leaving the feature start, lamps, animation, and the rest of the payout logic untouched. Two prize tables were patched: Table at $9C28 Table at $9496 All leading 01 entries in both tables were changed to 02. This forces the lowest possible Solid Silver prize to £1. The file is based on the existing checksum-removed master so no checksum is re-introduced. The working version is: Nifty Fifty - Grok - V4 - Solid Silver Min Pound WhatsApp Video 2026-10-18 at 00.26.25.mp4 NIFTY GROK 4 PROM 1 - 27256.bin NIFTY GROK 4 PROM 2 - 2764.bin

Does anyone have any other Summit Coin roms ? I Have Ultimate Nudge already, I am got the tech running on my JFruit emulator. If you are interested you can try it at Click to Play Ultimate Nudge

this has tonight interested me to look at what i did years ago, it was definitely a ball ache to change the codes manually which resulted in burning a useless chip that wouldn't work in a machine and of course just loosing the cost of the chips which are becoming more difficult to find. so I have started with AI tonight to do a program which askes for the code needed and insets in into the right place in my original code. this would then make it much easier to produce correct chips as there is no where to get them made these days. so if needed i may be able to make them in the future

Thank you. I appreciate it's tough going but I hope it will be useful for someone. These gambling blocks seem to annoy everyone these days! Back in the day, they probably saved a lot of people some money 😄

well done bernard. i will probably do NIFTY 50 today to rid the petty 50p on the solid silver so you at least win a pound. I unblocked the nudges and cash prize on STOP THE CLOCK so the nudges go to 12. it so far runs good. I think the club machine blocks were more aimed at the DOUBLE OR NOTHING gambles so the machines didnt get smashed up. can you imagine having 50 quid and do a double all or nothing and it lands on lose

Does anyone have an Electrocoin BAR-X machine where they can test / give feedback about my prototype reproduction board. The board "Universal 8205" is found in the very early BAR-X machines. You would just need to transplant the eprom's from your board. I'm happy to post to you and provide a return label.

Gentlefolk, Thank you for your interest in the removal of the Royal Exchange gamble block. It's encouraged me to post a similar document detailing how I did the same for Stake Up (and Multiplay) about six months ago, for all those who are interested in the inner workings of these machines. They made no effort to consider what you would win if your double-or-nothing gamble succeeded; they were, quite literally, a random 50-50 win or lose. The programmers were probably happy with this as the gambles were limited to £10 so nothing too calamitous would happen. With the new ROMs, of course, it could discover that it has paid £100! These were MPU4 machines and they used Motorola's 6809 code. Although this was built on the 6800 code which was used for the MPU3 machines, it is an order of magnitude more difficult to fathom. Do please bear this in mind if you look through the attached document; it is very much written for coders! Many thanks again for your interest and comments, Bernard STAKE UP AND MULTIPLAY GAMBLE BLOCK REMOVAL.docx

Gentlefolk, I've uploaded a new set of ROMs for Barcrest's Royal Exchange. The original imposed a gamble limit of £20 for all initial wins less than that. The new version will allow a gamble of the current win up to a maximum of £100. Here, I've attached a Word document explaining how this was achieved for all folk who, like me, used to think "How did they do that?!". Please be aware that it is not for the faint-hearted 😊 I'd like to thank chris217 for reintroducing me to the wonderful world of 1980s fruit machines, Sulzer Ned for drawing my attention to the idea the the emulated ROMs can be tinkered with and Eddie Coxon, who advised me of the programming language used and provided me with a huge manual and lots of helpful advice and hints. Now that you all know exactly whom to blame, I hope you enjoy the new version together with this documentation. Best wishes, Bernard ROYAL EXCHANGE GAMBLE BLOCK REMOVAL.docx

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"

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 .

Thanks for this, John. Exactly the same point was made to me verbally only a few days ago. The 'exchange for nudges' option ensures that you don't get a decent win and it doesn't offer it at all if the current win is too high. Ignoring the cherries is, I think, possible as the code stops looking for winning symbols once it finds a cherry. Telling it to stop looking appears fairly straightforward but you would then need to avoid the GAIN code which looks for an alternative when it finds a win. Obviously, it won't find one if the whole point is to ignore the lesser win. That is far more difficult. I'll take a look when I get some time. Please don't hold your breath 😊

I changed the nudge stopper to a maximum of 10 and i thought the CASH PRIZE needed some love so instead of getting a lame dead useless few pence for a feature that takes longer to get i changed it to Give the player more fun.... wow i really like my machine now 3 X REPEATS on the cash prize it holds sometimes on the SKILL as well. trust me it dont always give this much but it makes the CASH PRIZE now worth going for WhatsApp Video 2026-11-12 at 03.02.08.mp4

That would take me a couple of months to sort out

Heating the eprom did help recover some more data, but it's not a totally clean read. Claude has looked at the data and said it's the best set of reads yet with the die heat soaked for around 10-15 minutes at 60-70 degrees. I can send you the chip if you want to have a go at reading it? At this point, I've done as much as I can do with it. The rom doesn't pass checksum and so won't run but it's better than the first dump I did. rolatop_best_read_galep_heated.bin

I have been a long time lurker over many years, spent a long time fixing personal home machines. I have been working with a guy to bring reproduction boards to revive damaged (usually battery corroded) back to life. So basically, two guys creating reproduction fruit machine mainboards and game cards. Now obviously, these are blank boards and require a donor board, time and effort to build. Most of these boards have easy to solder through hole components which minimal skill level is required. Obviously some have SMD parts such as EPOCH, Astra IO3 CPU Card where more skill will be required. ------------------ Most boards range from £15 to £25, and some discounts can be made for larger amounts. I'm based in the UK but can pretty much ship anywhere but at buyers cost. Feel Free to drop a Comment or DM for any questions ------------------ When a new board is released for sale, BOM documents and Notes will be uploaded here: https://drive.google.com/drive/folders/1zteijgZ6kcggR_ZUyvWFackC2KUOpF-0 I do have a Facebook group (same as this thread title) where you can reach out to me to purchase.

One weird arcade in New Brighton, by the Marina had 2 of these. And yes, they are very additive. No tokens, but 2p play the version I played. Totally dark though, no flo tubes, which made it a bit more spooky. I thought I was dreaming this, but very happy this has become emulated eventually Statto

think the resources probably came from you - Some good pics might let the likes of Pook create a nice DX

Great to see electro mechanical machines in the releases. I have the actual machine

Excellent work Pete and thank you for making them available. Some of these bring back many happy memories of being a nipper on holiday in Newquay (Wales) in the arcade, especially the Brenco. Is it possible to download the MPU1 files to play in MFME as i have a fixation with these after resurrecting my Nippy Nudger. Again Thank you.

Hi all . Had to creare a new account as I couldn't get in with my old details , and I couldn't see any way to contact admin . Hopefully I'll get back in to my old account . Sammy

Some more information. I asked Claude to patch out whatever the code was checking for which was preventing the ROM from running. It turns out that the reason the game won't run is because the code is corrupted. So the ROM dump I posted here is bad. Part of the EPROM has rotted and the data is lost. The sound ROM is good. The machine was used on a canal boat and the humidity and close proximity to water has like damaged the EPROM. Claude was able to salvage 80% of the game code but it's not enough to make a good dump. I tried giving Claude another ROM by Eurotek Designs in order to re-build the missing data, but the game is too different and doesn't share any code with Rol-a-top. So until a good dump turns up or I can find another machine, I can't get this machine working. Paul

Hi, We never did anything with it, did you want for free? Just need to collect before 15th November , pref before in Princes Risborough, Bucks.

Thank you very much. I'm delighted you enjoyed it.

Great to see all these electromechanical releasees. Many thanks Pete.

Thanks pete

Thank you

Thank you

Many thanks

Thanks for these

Many thanks for this @pete_w. Bullion Bars was the first clubber I played legally. I won £16 that night, paid out in 50p's Back in those days it was about 32p a pint, makes you think then your are throwing 10ps in it. Is there any chance of payout sounds? Cheers WF.

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

Brilliant, thank you for doing it Bernard.. 🤩 Another challenge for you if you get time.🙏 This is an issue I think spoils the fun on Royal Exchange for home use.... When you exchange for nudges there's always a pesky cherry that stops you getting a better win, would it be possible for the software to ignore the cherry and nudge in a better win? John

Great work Bernard. Can't say that I understand it. Impressive though 👏. Thanks for sharing and explaining 🙂

Thank you, sir - I do agree, but I also wonder who would have risked a gamble of £50 or thereabouts forty years ago? 🤣
