It doesnt matter now anyway, I've destroyed the adjuster. The allen key pokes all the way through now and touches the chassis and I received a little shock, didn't get hurt but it scared the hell out of me. I'll take a look at the dips again. Is there any way to use a computer monitor with an arcade cabinet? I never really wanted to mess with the thing to begin with, but the width was driving me nuts. I'd replace the monitor but I don't really know how to discharge and I'm a little afraid to, also monitors are expensive and I already paid too much for this machine anyway.
Ryoshin:
I think you were right about it being on French, I turned all dipswitches off. My coinage issue seems to be gone, but i'm still getting bad U49 and failure in CMOS RAM in test menu.

EDIT: Now I'm getting extremely low sound. I can't change it in the test menu either, I mean I can but as soon as I enter it and go back to check it it has reset. It is also impossible to change difficulty as when I click on the menu the screen just flashes like it's about to change screens but just shows the same screen again, so basically it just reloads the test menu, no way to get in there. The difficulty setting thing I've always had a problem with just decided to throw that in there because i forgot before. Guess I also should have mentioned that the sound board light is on, but now I can't even hear any sound.
Malenko:
find the U49 and apply a lil bit of pressure to it, it should clear the issue unless the chip has gone bad. Its not a socketed chip, if you need to replace it, you need to de/re-solder it.  As for not saving the volume and difficulty, thats due to the CMOS not being in memory.

leave all your dips off except for 2,3,and 4 in bank 2. That'll give you free play :)


Where are you located? If you dont mind me asking, how much did you spend on the game? Theres a seller named Q*Bert_Op that sells PCBs he might have a replacement MKII for ya, I just got an MK1 from him for $60 shipped. (Now I just need to find a non Ultimate MK3 and maybe an MK4 so I can wire up a MultiKombat machine inside my MKII cab =)

I sort of regret telling you had to adjust the width coil now that its ruined, but I tried to stress you need to use a plastic tool and not a metal one , sorry.
leapinlew:
Gah! Holy crap Ryoshin, I'm sorry bro. I used a metal one on mine after doing some reading and the general consensus seemed to be that it would get extremely hot, but you can do it (especially if you turn off the monitor between adjustments). I had no idea it could even melt the plastic.

I saw replacement horizontal width coils reasonably priced. I feel real bad about this. Why don't you replace the horizontal width coil and let me know how much it costs. I will gladly pay, for a replacement coil.
