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.

I cannot find the U49 chip unless that only sharp chip I told you about is the right one. I'm located in Jacksonville, FL. I paid $325 for this, I think I overpaid a bit considering the shape of the cab. It's not an original though, like I said, and in the heat of the moment I felt this was a decent deal considering I've never seen a MK II machine for less than like 900 bucks. The thing was sitting outside and I booted it up to make sure it was working but I couldnt really tell about the screen issue because the sun was blaring on the screen, could barely see, could just tell it was working. I'm not too worried about the width coil anymore. The weird thing was just sticking the allen key in there fixed the picture, but I couldn't turn it, does that mean it's probably a cap problem?

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.

It's not that big of a deal man. The damned thing just wouldnt turn. Of course it could've easily been user error. Replacing coils/caps requires taking the monitor out and I'm deathly scared of that thing. What's the best/easiest way to discharge one of those bad boys? I've googled a bit, but didnt get too much into, maybe one of you guys could tell me the best way for a noob.
Malenko:
I'll pull my board out and take a pic of the U49 when I get home (in about 4 hours) as for the width coil, post in the monitor section. I know a lot about the MKs but I cant say so much about monitors.
Malenko:
OH MY GOD!
I cant believe I didnt notice this earlier!
YOU'RE MISSING A BOARD! The daughter board. I took pictures of mine, I couldnt find the U49 chip either but Im mega swamped with work and studying for my 70-680
Ryoshin:
You have an older revision than I. I have revision 3.1 and I'm pretty sure they redesigned the board and got rid of the daughter board if my research is correct.
