Solar Power Generator - it wasn't that hard but you only just had time to do it. So waiting for any 'monster' to pass and pass back more than once would stuff you.

I completed that particular game without knowing about that although I think I used infinite lives to do it. As I recall level 19 was a git time wise.

What I would do is look at what we have: A load of red wires so that tells me there is a common somewhere else - maybe through those screws I see. Then I would put a multimeter on each of the wires (so from the assumed common to each of the reds) testing for resistance. If that turns out to work (so not open circuit) apply using a variable PSU 5V DC initially across each and go up from there. It's going to work from the voltages supplied by the internal PSU I would expect so you know what to try. However better to wait to see if anyone else knows without guessing.

Well for anyone who wants to have a play I've done a hack of the ROM so the superhold bonus is now available on £1 play - attached. I say I but it's a big thanks to @johnparker007 who has already said how to bypass the checksum and gave me a handy way of knowing when the code is in the bonus routine. So for 25p or 50p play there is no change in behaviour - I've tested it on all 3 stakes and seems to be all good. Did make a schoolboy error on one run where the 25p stake magically became £1 stake Technical info: Although memory location FFFF1185 seems unused it's being read up along with FFFF1184 so I used FFFF1124 as a storage location. This is easy to change in the new bit of code I've written should it be discovered it is in use. As I've said before I'm an amateur Z80 programmer from the late 80s so this has been a challenge - it's took hours to learn the 68000 mnemonics and write some simple code using EASy68K to get the actual machine code values. Probably have taken John minutes to do what I have Today but I had a free day so it's all been good OCI71_0K_SH.zip

Here's a short showing the JP superhold and the Mega Streak on Oche! Oche! Oche! that I recorded the other day. Usually it won't let you get the MS but the steps meant it trapped itself. Coincidentally it looks like the modified ROM might not be far away going by a comment by @johnparker007 in another thread.

You are joking the £70 era was MASSIVE - there were so many machines with something on them and some empties thrown in. Died down when £100 era arrived and many players did give up but there's still bits and bobs.

The only two things I can think of are: If you are running MFME in a virtual PC environment - because you can save the state of everything (RAM included) like chop did in his vid for the betcom cheating deal game. Use a tool like cheat engine to speed up MFME temporarily for game boot ups. Both are not really smooth methods though.

Yes John I followed the idea at the time but I wanted to try and make it as much like the original so I rethought about it and decided if I could find the part that basically said 'if on pound stake don't include the superhold option whilst cycling through the others' I would see if that could be fixed by changing just one byte potentially. But it depends how that's done - as I said it could be a list of items as such and the same routine is used over and over. I know you are busy at the moment but I might come back to you at a later date with some (what will seem to you) basic questions. You could say - wait for it - I am after some pointers BTW thanks again for the initial identification of the stake memory location and how to sort the checksum if I do have a go at this ROM.

What's the issue with BFM superhold ? Going by @thealteredemu response is it something to do with trying to hold down multiple keys at once ?

This is a follow on from the thread titled 'Just an idea' by @Levartemit So first about the empty itself which I have been doing on and off over the last few days by hacking the RAM using the FME debugger: It's an awkward empty to do. Firstly so many of the reel positions have numbers on them so being able to get all 3 Jackpot symbols in line without needing to spin out at least one reel is a game of pure luck. When you do get it and it puts you on the board it knows not to give you a good number on the cash side (for MS) and will only ever give 2 bullseye symbols (you need 3 for MS) from the darts shots. Well that's my experience from the three jackpots I got. What you can do is try for 3 triple bars (or double bars) from the superhold if they are available instead. That's £15 for triple bars and you often get a chance to win a gamble on the cash side up to £20. Other times it just throws you on the feature board so you just take the most you can - usually off the darts shots. STOP THE PRESS - it's not an infinite empty but I was about £250 up at one point. So after the 3rd jackpot it did an Alien special and would not board for £65 and that includes not giving a bonus because you can board from other options on the bonus with the slow down. Being as the hoppers on them were £350 if full it would class as an empty I guess. Now onto the RAM/ROM hacking: I definitely could write a fairly seamless RAM hacker for this that would need the debugger open. I might be able to write a seamless RAM hacker for this that would NOT need the debugger open - not sure. As for hacking the ROM - I had a look using the FME debugger and there's just too much going on so I used ghidra as provided by @johnparker007 to look at the code. I looked at the disassembly of the functions and I could identify those that obviously are doing hardware checks. But the others mainly seemed to be just shifting variables around and I really couldn't follow it at all. When I used to do Z80 stuff I knew what I was looking for before I looked at the actual code - with this I don't - I mean I'll have to get some clues from John at a later date like identifying what relates to communicating with the alpha or what relates to reading a keyboard input, etc. On this I was going to use a different approach and that was find the routine that's cycling through the bonus options then see if there's a bit that doesn't call the superhold bit - but even that might be a list and it just ignores the last option or something - so that could be a count of 1 difference - not 02 where looking for the reading of the stake.

Nothing particularly good about this machine but I'll send you a PM

Interestingly the watchdog (the code that triggered the critical error) didn't work for the Barcrest Indiana Jones £70 empty - you could take the whole hopper.

The admin @pete_w will sort it out for you when he next gets the chance.

I assume it was so that the deal game was achievable to a casual player. I remember this guy (not seen him around for a while but he used to throw a few quid at anything) showed up whilst I was on a triple and said 'never seen it offer that when I've tried it' referring to the deal game. Of course he'd never risk 50 quid or whatever and as it was always being done thus would never see the deal game nor a bust message.

Not having a go here it's just that I have read the last few posts but you were still playing the randoms (tongue in cheek on that description lol) up until recently where you did a vid saying enough was enough. Not every one AFAIK and even then it depends on the level of advantage anyway.

Try using cheat engine which can slow down or speed up the executable.

I'm reasonably sure there was something on Big Bucks deluxe. IIRC only ever saw one and it had gone when I had the info, but can't remember what the trick was.

Plunder and Lightning is pretty much the same thing

As I understand it the problem with the Cash Attack was when it powered up it reverted to one stake and therefore wrongly assumed it had been paying the MS from that stake and therefore value was still there in the actual stake - this is a different issue to many of the others vulnerable to plugging.

I suspect we have the ROMs but someone such as @logopolis or @Geddy or @johnparker007 will know for sure. They can probably point you in the direction of someone who can burn a set for you, I expect for a small charge.

Am I missing something or do you just need to tick the drag reels option ?

Don't know if Windows still has it but there used to be a startup mode (in addition to normal and safe) where you picked whether each driver/service started up - maybe use this to determine if something specific is bothering MFME.

The admin @pete_w will approve it and then you will be able to download.

Did you checkout the thread at: Might find that of use @thescientist

This is true of all recent Bell Fruit machines that give a hint of next Number will be X. Even when invincible going against the hint will kill you. Yes a lot of the Betcoms can get into a situation of offering £100 cash but will not offer the Mega Streak (or at least not red) even though that could just give a flat £100 anyway.
