    Boot Camp #2 - CPS1 A failure

    Who loves dead A boards?? This one at least shows me a bit of color pattern on startup, giving me hope. A boards are hard for me to troubleshoot currently because so much of the pcb is obscured by the B board. No room for my normal probes :( so I just ordered a cable kit that reorients the A...

    Boot Camp #1 - Gundam EX Revue

    To add to my Lucky Moron PCB Repair series, I decided to start this sub-chapter called Boot Camp. Previously I fixed things that were just sort of not-working, but now we'll really get into it where the board doesn't even boot. To add to the fun, I don't actually know what I'm doing and don't...

    Lucky Moron PCB Repair - #4 Killing Blade PGM Cart

    Lucky Moron PCB Repair Episode 4: Killing Blade PGM Cart (or: Fluffy's carts are superior) This game got swapped into a lot deal at the last minute when the seller couldn't find his promised Dynax mahjong title. Despite it's lack of worth I did receive a video of it working beforehand, and upon...

    Gunbird 2 Audio Improvement [WIP, help wanted]

    I've been working with Psikyo boards a lot, and recently noticed the audio quality differed greatly between the two PS5-pcb-layout games, Gunbird 2 and Strikers 1945iii/1999. Gunbird 2 suffers from what seems like video interference. This issues has been mentioned before on AP and elsewhere, but...

    Lucky Moron PCB Repair - #3 Strikers 1945 II

    Lucky Moron PCB Repair Episode 3: Strikers 1945 II (or: Measure Once, Cut Anyway) Even though I know about The Glitch now (awesome stuff @Hatsune Mike!), I still suck at Dodonpachi and can't even 20cc it, so it was time to put that board away and load up to some good old-fashioned Psikyo...

    Lucky Moron PCB Repair - #2 Strikers 1999

    Lucky Moron PCB Repair Episode 2: Strikers 1999 (or: Sold "Tested Working 100%") Symptom: eBay seller willfully ignored the boot-up screen where it CLEARLY SHOWS "WORK RAM NG!" and sold the board as working anyway. Game also freezes several seconds into game-play. Why do I even eBay anymore...

    Lucky Moron PCB Repair - #1 Double Dragon

    Lucky Moron PCB Repair Episode 1: Double Dragon (or: how you would fix this pcb since you aren't @caius either) A local collector recently listed multiple boards for sale, and the combination of both a) geographically-nearby and b) reasonable-prices put me into a buying mood, even though...

    PCB Preheater

    I’m considering getting a pcb preheater for making smd work a bit easier and cleaner. Right now I just heat up the back side arbitrarily before I work on the front, but I’m well aware it’s not ideal as my pcbs inevitably warp slightly by the time I’m done. I would probably be satisfied by a UV...

    Not mine: Fighting Bujutsu full cab Not mine. I should buy it just for the pcb... But I don’t want to do that to a full cab so here’s hoping someone is also a rare fighter fan and can scoop this up.

    Nanao ms-2931 buzz (fixed!)

    Been living with this for a while but I feel like I should address it now that flybacks are available. If it’s the flyback... I don’t see any cracks or arcing. this buzz is pretty consistent, I do think it gets slightly louder as the tube warms up. It will buzz at a higher rate at 24 or 31khz...

    [WTB] Star Trek Voyager security button

    Hi. Did you click on this because you have a Voyager gathering dust somewhere? Great. Sell me the stupid security button. Maybe the megajamma board if you want, I have one but two is always nice. I just need that button thing that looks like a battery but isn't. WTF is it even anyway??!

    Weird (to me) potentiometer code

    Hi All! I’m used to seeing potentiometer codes on stuff where the first two digits are a value, and the last digit it’s a factor of 10. So “202” is 20 x 10^2 or 2k ohms. Well I’m looking at 239. It’s not 23000000000 ohms... it meters at 2k (so 23 = 2 x 10^3 = 2000) so I’m wondering if the 9...

    MS9 remote board potentiometer values

    Anyone have a Nanao ms9 remote board handy? Could you grab the potentiometer values for the white trim pots? I melted mine. And I can’t see the values on the schematic. Yay! Otherwise I’m gonna buy another and store them here for posterity. I found a thread referencing the black ones but would...

    Time Crisis 3 contrast / sync [solved]

    I have TC3 running on a PVM, and, well, it looks like ass. For a long while I just assumed my namco IO just had some old caps and that its video was impaired. A few days ago, I replaced the io, and sadly had no change in image quality whatsoever. Then I learned that 2x6 games have a...

    Hi All. Posting this on reddit crt also, but a bit later today or tomorrow. You get a head start! I bought a Sony PVM-14L5 PVM for $110+shipping last year. I meant to keep it around as a test bench monitor but it's just sat next to my desk literally all year. It has a color issue on the right...
