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

Sweepstake next?

Should have that file when I did some 10 years ago. Will have a look... But the chip on my board was not locked so I just read it with my dataman pro.

Hay @jane.sharpe7 the buttons are not set right in the background on this game so test mode wont work... but you can add the right ones for back door (I'm not very good at this but you'll get the idea I hope)... Go to design then select Edit Mode right click & Draw a checkbox - Right click on it & change it to value 23 - this is the back door and when checked gets you to back door open repeat and draw another and assign value 22 - not sure on MPU4 but this gets you to this state when checked - VPT on the display and the start button cycles through in & Out. Draw another button and call it 21 (I think) and that when checked and un checked gives test plays - not sure what value the test switch is as I don't really know MPU4... think this is Refil. When you've worked out what the switch numbers should be, un check them all and update switches into the Game configuration area (think this is right for service, refill and test???):- you can work it out by trial and error... Uncheck Edit Mode and the buttons work as you think they should. Save on exit Enjoy

Will do 👍👍

If at all possible could you dump the roms please.

Cheers nick ,, I wouldn’t imagine there would be many of these around now,,,

IVE GOT A PROBLEM. THE new classic layout dont let you go into test mode the door switches dont work. i need to force play so i can see the memoyr debugger for the cash prixe as ive incresed it to 1.50p and ive increased the nudges from 4 to 12 instead of 1 to 8. the nudges work brilliant. the 1.50p will pick the 1 but the animation steps are still 20p to 1 pound. i will be there forever. is there no old version of this on older mfmes
