Hi there, I am trying to make the PSU of Korean House of the Dead 1 "upright" cabinet work, it almost works, model 400-5306CE-01, exactly like the one from this image: I'm testing the power supply individually before trying it in the cabinet for first time, with a dummy load in the +5v side...

Found them, after some intense reverse image search, they're ELR-12V and ELP-12R And found a better picture https://www.jessewolcott.com/korean-ddr-pad-connector/ Unfortunately they're very hard to get unless purchased by a large amount.

Looking for a spare Namco 54XX custom chip to repair a Xevious board. Original or repro is fine.

Looking for some assistance please with these ones from a Korean DDR cabinet, it didn't come with the cable that connects the cabinet to the dance pads, so I need to build one myself, since also from both sides the connectors are the same gender, but couldn't find what they are. Japanese DDR...

I plan to replace all rams with new ones, just haven't been able to do it yet. I've purchased these, hopefully they are the right fit: GPU: IS42S16100H (512K Words x 16 Bits x 2 Banks) (16-MBIT) - confirmed as good for graphics ram CPU: IS42S16400J (1 Meg Bits x 16 Bits x 4 Banks) (64-MBIT) -...

I just got a Tecmo Gemini Wing and it was displaying upside down in my cabinet, couldn't find it in your document to see if it allows flipping (later I found it doesn't), ended up plugging the yoke into the other connector that displays the flipped image. Here's info about the game if you'd...

Yes. I would also check the uPC324C (LM324) and uPC804 (TL084) opamps if sound does not come back, probably a good one could be piggybacked on top of the suspected one

I don't think it could be possible, since their sound hardware is quite different, and the System 32 Multi does not even use its single YM3438 for sound, only uses it for timing So basically the System 32 uses FM (6 channel) + FM (6 channel) + PCM sound chips while the Multi 32 uses a just a...

Hi there, I'm facing a very weird (compared to others I've seen) sound issue with my Outrunners board, sound pretty much works but the music tracks get more and more crowded with notes that do not stop, it's like they're all sustained. When going out of the sound test menu whatever last note was...

Thank you for your time to reply the questions!. About the Sauroid, I got it from an arcade cabinets lot that was stored for many years in not an ideal environment (humid sometimes, rust), I'm sure the Sauroid and the rest of the lot was imported into the country 25+ years ago. Got the pedestal...

Hi guys, I find myself in a situation where I'm missing monitor parts to complete some cabinets and bring them back to good working order. Matching of these parts is a bit of a new topic for me so I have this couple of questions: Konami Sauroid I've got this behemoth cabinet that I would love...

Nice. What tools did you use for taking it off? and how do you plan to do the reballing? I might be in the same situation but not sure how to do it so I'm watching closely

I'll try it as soon as it comes out - my hardware is ready! 8o

Hi @bobbydilley, I am trying to get Virtua Tennis 3 to run but can't get past this "wrong ELF class: ELFCLASS32" error. Tried with Ubuntu 20.04 and 22.04, same issue. Also with freshly built lindbergh loader or release binaries. And with and without these variables LD_PRELOAD=lindbergh.so...

Oh I get it now, thanks for shedding light on the topic!. My multimeter is not even RMS so I went with the scope, measured between pins 9 and 10 of the CRT socket: I see the 15Khz frequency, and a RMS reading of around 3.5v, so, time to swap resistors with confidence. There it is, the green...

Hi guys, I have recently reflowed/fixed cracks/recapped the Hantarex Polo 25 chassis of my Revolution X machine, so I could try powering it on for the first time after who knows how long. Monitor works, but after trying to calibrate it as best as possible I can't reach a bright lively picture...

Hi guys, I find myself with this Sega Naomi board that has let me down. It's my first and only Naomi board, I know it used to work, then was stored at a not very dry place for around 2 years, then came to my hands to seem to perfectly work for a couple of hours then hang in game - screen froze...

Hi, found the EC34 capacitor value at the motherboard service manual, page 21: C10U16EL, I would decode that as as a 10 uF 16V cap Also got an almost discernible image of it, from a MSI MS-7142 photo, has a similar VIA VT1617A audio section

Here are Sega Star Jacker schematics that I've seen others use to repair Wonderboy: https://drive.google.com/file/d/1AYv91Pfp4V8LqV062SefD2vPYrT73zQM/view About the 74LS157s, the usual thing to check is for stuck/nc outputs (pins 4, 7, 9, 12): https://eater.net/datasheets/74ls157.pdf. If you...

Hi, those RAMs you replaced might be work rams, if you turn on the game w/o them, does it boot up?. If those ROMs are good, and you're sure they're related to the failing sprites, with a multimeter you could check what's the destination of their data lines, they could go to a failing logic IC...
