I have a Super Kaneko Nova System motherboard, but I don't have a ROM board. I connected the motherboard to Jamma, but nothing is displayed on the screen. Is this normal? If anyone knows, please let me know. The BIOS is Japanese.

I got a pxlmod Seibu HB-45A reproduction for a Raiden II board with the classic squeaky audio issue, however because I'm a colossal dumbass I accidentally followed images from a different maker's reproduction for install orientation which ended up being backwards for the pxlmod one and I think...

Hi , I have a HAS supergun. When I got it, I wasn't able to get a soild usb adaptor for controllers/sticks(everyone was out of stock), so I got the "BROOK PS4/PS3 to NEO•GEO Super Converter", but I have always wondered if these are even any good? Or if there's anything better that's available...

Good morning, I moved my arcade machine downstairs, while doing this I accidentally stepped on the cable and damaged a connection making the power not work. I recently repaired the power so that the machine turns on, however I have no video. Sound and everything works just no picture. Any...

Hello everyone. I am swapping a model 2b rom board and the board I am swapping it with does not have the little black peg that fits over the center screw holes. I can rotate it but it does not unscrew. I want to do a part for part swap since I don't know if it's there to prevent any kind of...

Hey Guys, I'm just looking for a bit of feedback on this. After purchasing some KOF move strip art I started to realize that it looked really silly given I'm always playing different games. I was trying to think of how I could utilize the space better and saw something on one of the candy cab...

Hello everyone, I need some help with my CPS3 that always had some problems with the cartridge slot since I bought it about a year ago. I got this board from a guy from another city so I couldn't test it too much before I pay. The thing is that this board started having some trouble since day...

Hi Arcade Projects Community I have become the proud owner of a CPS3, but I haven't been able to play because of a video output issue. I'm a bit out of my depth, would appreciate some help so I can get 3s working. When I power on the board, the image is skewed. Pictures below. When I first...

I bought this MV1A board off aliexpress and made a supergun. Works fine but on inspecting the underside of the board there is a missing component labelled D5, near the Jamma edge. Does anyone know what the purpose of this smd is for and if its recommended to replace it? It looks almost like a...

Hi all, So here is my question, I have a few CPS2 games, and it's real hit or miss when I open them whether or not the plastic hooks connecting the black bottom shell to the colored top of the shell break when I open them. Is there a technique you all have found to keep these hooks from...

Recently, I got a Namco System 10 running Taiko no Tatsujin 5. I hooked it up to my system 256's power and the game runs fine - it goes through its opening movie and the attract mode without a hitch-, there's audio output, but, alas, one thing has to go wrong: neither my new monitor nor my 4:3...

Howdy all. A while back I bought a few Undamned PS3/360 decoders from Paradise Arcade and had JammaNationX wire up one of his Atlas boards with the power needed to use them. Got the adapters and plugged em into the Atlas board and the corresponding wires, but I don't get full signals from them...

We built this arcade box (below) from scratch in 2020, and my son decked it out with RGB lighting. It was a labour of love. We built the hardware with a RetroPie running on a Raspberry Pi (either 3 or 4) and Emulation Station. We picked up a cheap pack of joysticks and buttons and an XinMo2...

Looking at a MV1F main board, that reports a video RAM error with the stock BIOS. With the UniBIOS it reports a non-descriptive hardware failure (no memory address listed) but can then bypass the error and run as normal. When using the NeoDIAG BIOS, or when using the stock and UniBIOS without a...

Hi, I'm new to the arcade scene, and I'll be getting my hands on a Rhythm Tengoku cabinet. Does anyone know the kHz of the monitor that it comes with? To my understanding, most Japanese Naomi Universal cabs are capable of 15Khz/24Khz/31Khz frequencies. I'm trying to find out because I'm...

Hi everyone, So I see a lot of nice pre-built superguns online that cost around $600. I bought this cheap(but probably still overpriced) one on Yahoo Japan, it works fine, but it got me wondering what are the nicer superguns doing that this one isn’t...

Does anyone have scans of either one of these manuals? I'm interested in what they have inside ...

Hello everyone, Question level beginner. I got a mv1b and I installed a battery holder on it, but saves are not working. I just took off the old battery and installed the holder, I didn't not remove anything I would like to use it with ml2032 not cr2032. I tested the electric tension on the...
