Any Neo Geo AES owners?

Yep, that's exactly my thinking, I was wondering how MVS slots could possibly differ in size!

However, the pop and whiffy smell (that could have been dust) is worrying. Jochen has offered to send me a new board though so I'd rather not touch the MAK Strike connector and leave it be. Don't want to affect my right to return the goods to him (unless he gives me permission to trim it down of course).

Very strange about the MAK width considering he has pictures of it hooked up to a one slot MVS on his site and it says the following:

This kit contains:

- MAK Strike with case fitting exactly for MVS NeoGeo one slot boards.
- External Power Supply with MOLEX connector giving 12V, 5V and GND

Are there two versions of the MAK or just one? One "consolized" and one not?

Hopefully the MVS is not fried though. From your pic the jamma pins least connected were the ground ones since they are on the outside. If you still plan to return the mak then just get permission to shave it and try it out.

I bet after all this though it's fried. Just my luck!

I'm going to check with Jochen and see if I can get permission to trim the edges down to test a flush fit. See if my MVS is wrecked completely or not. I have no Dremel alas so a stanley it is.

If not I'll just send it back and wait for a new MAK Strike.

I bet the MVS is fine (if it was in working order prior to you using it ), they are more robust than you think, and you probably just caused a bit of a surge etc.

Andrew76

If nothing else a valuable lesson was learned never to power on anything jamma related unless all connections are correctly fit together (and the correct side up). An mvs 1 slot is much easier to replace than a rare/expensive arcade pcb.

It looked grand. I powered it on, the display showed Unibios and then some crosshatch stuff when I put Art Of Fighting in to test (as I have 2 copies of it). It never booted the game though, I just knocked it off and left it. I think the pop and the burning plastic whiff came at that point.

Shoved in Fatal Fury and got the green screen with flickering blocks of garbled colours.

What bothers me is when I first ever powered it on, the Sync Strike LED was on. So it was getting power. Now it's not. I wonder if the SCART cable was wrecked?

Andrew76

Hold on, you put the game cart in before turning on the mvs.

If you get a crosshatch like that on boot up, it means the cart is either dirty or the slot is.

As does a green screen with flickering blocks.

but I'd rather send it back and have a snug one pro-cut.

If he designed them himself, he likely ordered the components in bulk. I'd say all of his jamma connectors are the same size, they look like the standard size anyway.

He'll probably just use a hot blade to slice off a few mm each side. A dremmel being round-tipped, won't give a pro-looking finish but a nice sharp blade straight down will look pro enough.

Regards the pop...you might be lucky in that the power just arced from one connector to the next causing a surge. Fingers crossed anyway. If not, a pop usually indicates a component somewhere just had a bowel explosion.

Pyongyang

Jochen is sound as a pound. He's mailed me back super quick saying I can trim the JAMMA connector down and test it out, said it helps him with finding out issues anyway. I'm going to do that tonight and try it out.

As for how I powered it up first time, I basically had everything set up ready to go (like a console if you will). Cart in place, all bits connected, powered on and then... well, you know the rest.

I'm going to try cleaning the contacts, see if that helps with the display issue. Going to heat up a craft knife or stanley and trim that connector tonight. See what happens.

I really hope these MVS systems are as robust as you guys say!

Pyongyang

Oh and here's a good one for you. When plugging in my SLG to my Saturn last night I electrocuted myself on it.

o1s1n

Haha, ouch. It's them scanlines, they're unhinged

I must have some mad electromagnetic field as I'm always doing that. All the time on everything.

Last time it happened was yesterday. A coke can in Dunnes gave me a static shock

Pyongyang

The SLG is unreal. Makes Donpachi look utterly amazing. Great device. The ability to tune the scanlines with the dial is a work of brilliance. Better than the dipswitches.

The shock last night was actually quite brutal. Oddly it made me play Donpachi a lot better than I normally do though. I was happy out with my Saturn last night while my stupid MVS was tossed aside in a rage.

Pyongyang

OK so I shaved off the sides, it now sits flush. I cleaned the game and MVS contacts. I tried taking everything apart and connecting only the MAK Strike and the MVS direct to my TV via SCART only. Same thing.

This is a screenshot of my PC monitor, it does the below but when on my TV I could hear white noise and a continuous clicking sound too.



The MVS is shafted isn't it?

Pyongyang

Oh dear.

o1s1n

Oh noes

Any other setup you can try it on? Just in case?

Andrew76

That doesn't look good.

Maybe a silly question but you've tried other carts on it rather than just the one when the problem occurred?

CathalDublin

If your getting video it should be fixable, bad trace on the board somewhere or bad solder joint possibly

LOL
look for things like this on the mv-1b board or bad connections/shorts around the unibios

Looks clean. I took the black plastic shielder off too and looked at the whole board. No explosions, burns, bad traces etc. Not that I can see with the naked eye anyway.

I did sniff the board too...

Pyongyang

Heres a photo of the board (excuse file size):

i would had used an continuity tester from a multi meter,which gives beeps if there's a current running through a line.

is that glue on the caps?.

some mvs suggestions here-

Neo-Geo MVS system has garbled video Neo Geo 2 slot board worked and passed all RAM tests but video was messed up. The normal title screen was squished up into the upper half of the screen. The bottom half of the screen was a jumbled mess. During gameplay things on the screen changed on the upper half and bottom half at the same time.
Replaced one CXK5814 IC. IC tested fine on self tests and on an external tester. It had an internal addressing issue where the top addressing line had failed. When addressing the top half of the chip it would restart at the bottom of its memory. It would pass the simple memory tests of the Neo Geo and the external tester. Replacement of the chip cured the video problems.

Pyongyang

I think we're realming to depths where I'm struggling to stay afloat here lads... would I be better off just getting another board?

Not sure on the caps, it looks like glue I think...?

ondafly

Do you have a voltmeter ? Just to check your getting 5v and 12v at the right pins ?

o1s1n

Might sound like another obvious one, but have you made sure all the dip switches are in the off position?

Pyongyang

OK, Dip switchs 1, 2, 3 and 4 are set to OFF. 5, 6, 7 and 8 are set to ON.

Don't have a voltmeter.

CathalDublin

Sorry for another obvious but have you
cleaned the edge connector contacts with a rubber/alcohol/Vaseline/the womans nail file or the likes, because they look a little bad

Pyongyang

Yep, cleaned it, set all dips to off. Just tested it now. Same result.

o1s1n

I wonder is there any chance your Supergun fried?

What you really need to do is to drop that MVS board into a cab/other supergun or else try another PCB in your supergun just to figure out exactly which one it is.

Andrew76

I'd offer my services here although I'm probably a bit far out of your way.

CathalDublin

Does the garbage on screen flicker or is it the same stationary image every time?
When you plug the MVS in without a game inserted is it the same as if a game is in?
