    Repair log: DoDonPachi Daifukkatsu

    symptom: didn't boot, bought blind from eBay cause: main RAM was bad; replaced, board started up perfectly time spent: 30 minutes; 20 fixing it, 10 selling it afterwards having a chuckle at pearl-clutchers losing their minds that someone would buy a board that looked like an easy fix & sell

    Universal JAMMA versus kit

    My goal was to get Splitfire out of the way so I can properly focus on this without burning myself out. I'm back on working on a version that reduces this to one cable through input multiplexing. However, the unavailability of microcontrollers due to supply chain issues makes this a little...

    NAC Splitfire: JAMMA streaming solution

    That depends on if the HDMI device will accept 15KHz horizontal scan rate and with composite sync over the HDMI port. In theory, it could work, but in practice I would not expect it to. The El Gato ones are famously picky as it is, as I remember. The OSSC is a recommended prescaler. I use mine...

    Storefront is nearly ready. I think what is going to happen is the page will just go live quietly, and I will post the link in this thread a little bit before it is shown to the public.

    "Sold" FAULTY KONAMI PARODIUS DA BOARD

    I will take this board for $80 USD if it is instead a broken Surprise Attack.

    Actually, the very very very first version did have holes IIRC. I will consider it if there is room on a future revision (which I will make to correct my tiny clearance error).

    NAC Splitfire: JAMMA streaming solution

    I've got a huge pile of boards. There was a little bit of factory fun and there is a tiny amount of manual work on my end to make them ready. The Hirose JAMMA edges need to be soldered on, as do the audio transformers. I made a tiny component clearance mistake so I had to trim two pins off...

    Need help with Puyo Puyo Tsuu convert: no garbage Puyo !

    https://github.com/mikejmoffitt/puyopuy2-hax Comment out the "sound.a68" inclusion in "patch.a68" as this went in the direction of importing the Puyo 1 soundtrack into Puyo 2 and that's not what you need.

    Astro city monitor sync issue

    Cold solder joints are common. If you have an MS8-29, there are H and V hold pots on the remote board as well as on the main board. Both should be checked. If the monitor has never been pulled to do basic preventative service, then it would be wise to do that now.

    Boards are stateside, gotta fill out some customs forms.

    PSA: MS293X, faulty chassis can break the tube

    The board uses an IC that can be acquired NOS from a few vendors, and aside from two capacitors this board is not too fragile.

    Nanao ms-2931 buzz (fixed!)

    Just a heads up: I wouldn't run the MS-293x tube without a neck board without some serious caution. Pin 4 - often unused on tubes of this shape and age - presents the full ~28kV through a large resistor: When I say large, I mean that it's so high resistance that it is immeasurable with my...
