I have a Superstars board which initially didn't work at all. I reseated the ribbon cable and got the board to load and play. However, there is no sound, only a whine when the volume is turned up. Culprit?

I am trying my hand at wiring up a Legend of Kage to Jamma adaptor. So far my wiring has yielded no results. However, I do know that the board uses a -5 voltage and that neither the edge connector or the cabinet I am testing on uses -5 (it's a neo geo so it isn't used). Would this (no -5) be...

Think I put this in the wrong section before. I'm messing with a surf planet board I got as part of a trade. When I plug it into my Jamma (with Surf Planet filter board also installed) I am getting a lot of interference in the picture. The game plays, the picture just isn't clear (I attached a...

I'm messing with a surf planet board I got as part of a trade. When I plug it into my Jamma (with Surf Planet filter board also installed) I am getting a lot of interference in the picture. The game plays, the picture just isn't clear (I attached a screen shot). I am running the board on a Neo...

Hello, I recently got a 138-in-1 Classic Horizontal Multigame JAMMA PCB (or Classical Game as the manual calls it). When I install it in my Neo Geo (with a Neo to Jamma converter installed) the initial load screen comes up off centered and then jumps around on the screen, never centering...

I need help identifying this board (see attached pictures). I was told it is one of the 1940 series of games. I got it as part of a package deal on some machines and it came with the control panel (with the markings for one of the 1940 series games, but no name) and the wiring harness. The board...

Just picked up a Blades of Steel cabinet today. It is in the original Konami cabinet and besides someone tinkering around with adding a computer exhaust fan to the back door (or is that supposed to be there?) it looks to be all original. I had to give all the buttons and the track balls a good...

Does anyone know where I can find the large buttons like the punch buttons on Blades?

Picked up a Rough Ranger board for cheap. When I plugged it in to my multicade I have notice that the score portion of the playfield is distorted like screen curl (but this is on a flatscreen monitor). No other part of the screen is distorted. What could be causing this? Had a Double Dribble...

I am installing a CGA to VGA converter (model Gbs8220) board in my Neo Geo cabinet and would like to use the optional rgb converter cable included instead of the 5 pin (cannot find the right kind of 5 pin connector). Question is this. The wiring diagram lists a h sync wire which is not on the...

The music at the start of the game and during the intermission between level 5 and the next board is scrambled. All other sound effects are fine. I have been told this is due to a "melody chip" like used in doorbells. I have not been able to find a picture that identifies this chip. Is it easily...

Just wondering what it is worth. It is currently disassembled due to the size of the machine but was working 99% a few months ago (had to move to a smaller room). The 1% is due to a wire breaking off one of the pedals. It may be solderable, since it works when touched back to it's original...

I am contemplating turning my Phoenix cabinet into a jamma cabinet. Will the existing power supply/switcher (both original) in the Phoenix cabinet work for Jamma wiring? If not I have an old power supply and switcher from a Killer Instinct cabinet. Would that work? Just want to be sure of what I...

Will a RGB/CGA/EGA/YUV to VGA Converter work with Neo Geo wiring? I ask because my current monitor is slowly dying, and I would like to swap it for a flatscreen monitor. However, I want to be sure it will work before diving into this project (I also plan on installing a Neo to Jamma converter...

My game room is full so I am contemplating trying to sell my Phoenix machine. However, I am not sure of it's value. The cabinet and artwork is in good condition. However, it has a few issues the first of which is that the monitor is going to need to be recapped. When powered on the image is...

Picked one of these up a few days ago. Are they Jamma?

I was at Hershey Park yesterday and saw a Q*Bert's Qubes machine in one of their arcades. I noticed that the cabinet was a Q*Bert cabinet. Was this game simply a conversion kit kinda like Mrs. Pac-man from a Pac-man? If so, does any one have these available? I know someone was selling a...

Recently picked up a Contra board which I believe to be a bootleg. When I install the board and power on my multicade I am getting sound effects and music, but am only seeing random white numbers on a pink background. I coined up and started a game and the buttons seem to be working (could hear...

This must be Phoenix issue week. The monitor has always had some issues with minor screen curl on the upper right hand corner of the screen, but now it is taking some time for the image to appear on the right side of the screen (It slowly draws in pixel by pixel). Also the color/brightness of...

What would cause the music to scramble but not the other sounds? Past experience tells me a bad rom. If so, which one is it? Thanks in advance for any help.
