after the S18 case I wanted something for my S16 multi. There are 2 variants, one has a cut out for the DIP switches and the other uses a modified version of the selector board. There might be other selectors out there and I think there is also a version of the multi that has the DIP array in...

I had a few Sega System 18 rom boards that I wanted to better protect. Came up with a case design that fits both the short and long rom boards. Let me know if I can improve the design. You can get the files here: https://www.printables.com/model/836536-sega-system-18-rom-board-case

Read somehwere that you can switch the Super Nova Motherboard into Spinner / Knob mode. After some digging and trial and error I managed to get it working. To enable Knob mode you have to put DIP 1 to on which will put the board into test mode on startup. There go to the System Configuration...

This has been in the works for a couple of month with Alberto. To create tray for the joypad connectors, I fired up Fusion 360. The idea was to use mitsus nice maple adapter and design something that could be 3D printed. Alberto sent me the measurements of the mounting points and the cut out in...

I always wanted a Rhythm Tengoku Panel for my Naomi Universal Cab. After seeing skate's Panel, I reached out to Alberto. He said that he already had a panel that would fit the original Sanwa buttons, just in smaller sizes to fit the available space. After a Rakuten -> Buyee journey I had the...

I have an asia region a-board that developed a colour issue. The game plays fine but the colors are all mixed up. You can see it in the color bar screen. Any sugestions on what to change on the board? I replaced most of the ram and a couple of the TTLs.

Another L-System PCB on the table. This Raimais is stuck in an infinite reboot. Sometimes it will get to the titlescreen for a split second and then show a coin error. When I flip the test dip, it will show 'TILT'. Desoldering the PC050CM did not fix anything, so I think the issue is with the...

@evilsim did request this a while ago. Finally got around to scetch it up in Fusion and test print it. Grab the file here: Seimitsu MS Mounting Plate by nnap - Thingiverse

I have a completely dead FH board. When I follow the reset signal I can see it trigger on pin 6 of the TC0220IOC. Based on the schematics that I found, pin 8 should output the reset signal but it stays low. Is the chip shot?

A friend asked if I could 3D print a replacement for the LS-32 Mounting Plate on a SNK Panel. Did a quick model and it works fine for him. Grab the file here: https://www.thingiverse.com/thing:4630723

With the Monkey Ball Panel completed, I had a spare stick from the set to give a shot at Afterburner Climax. The sticks I got off YAJ are angled. By removing the middle section, I was able to mount the stick correctly. Due to the hole alignment, it sits a bit lower but is still works fine...

I always wanted a Monkey Ball Panel but they are quite expensive and hard to find. A while ago I stumbled uppon these on YAJ: the joystick itself is the same Sanwa base as the Monkey Ball stick. Only difference is a shorter and thicker shaft. A friend was kind enought to lend me his Monkey...

I have a Lindbergh setup that I currently run with an external ATX PSU. To make for a clean install, I would like to use the NUC Sun PSU to power the Lindbergh. I previously tried to run a PC motherboard off the Sun PSU but that did not work. I think there is not enough amperage on the 12V line...

Got a Chihiro with Error 02. Which of the boards is the Main board? Is it the Xbox side, the board with the CR2032 battery or the media/netdimm board? When I start the system, I get the Error 02 message. On the filter board the green LED is lit. On the media board I can see a red LED through the...

I have an M72 board here that I used as a donor for the M72 multi. Whilst working on it, I am replacing the caps. I noticed that there is one cap missing on the M72-C rom board. The silkscreen identifies it as C1. It is near where the extra audio cable is connected to the board. Does anybody...

Putting this here for others that might run into the same issue. I have replaced the noisy fan in my Atomiswave with a silent fan. Hooked the 3 wires and there was no sound from the game, just a buzzing sound that sort of sounded like the rpm of the fan. After a bit of research I found out...

I have CPS2 A-Board that displays wrong colours. The colours are all over the place when I look at the test screen, so I suppose it has something to do with the palette ram. Does anybody know where that is located?

question to the experts. Would it be possible to match a Sanwa 29E31S Chassis with a Nanao MS2930 tube if I use the convergence ring and yoke from the Sanwa?
