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

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

Thank you

Thank you for posting, this is a very interesting read and extremely informative.

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

Many thanks 🙂

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.

Much appreciated, many thanks

It's coming along Play Big Apple

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

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

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

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

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 😄
