    Irken (MiSTer) JAMMA Expander

    @andynumbers it’s usually fine but for small pcbs it’s a problem. Cv-1000 included! If you swap the psu, check if this is coming back in stock, it makes it easy: https://www.arcadeshop.com/i/1159/taito-etu-3mv51-m4100023b-power-supply-kit.htm

    Irken (MiSTer) JAMMA Expander

    @Mackie for just voltage measurement, JNX Atlas / Voltmeter is a fine substitute for the reco /tangent

    Irken (MiSTer) JAMMA Expander

    @andynumbers you should run a stock egret2 psu on a 100v stepdown. I’m betting you aren’t, which is why you can’t dial its 5v output low enough.

    Twinkle Star Sprites: debug & dueling cakes

    well I think I've done all the easy stuff now... I have a build where it boots to cake fighter directly, and you can't use D to exit. Also the "jikken program exit-d" fix layer text is moved higher up the screen, and replaced with "Cake Fighter 99-99". Now if I can just figure out how to...

    Namco 369 Supergun setup question

    I am not sure which jvs ios the 369 will accept. It’s possible that it is picky

    Namco 369 Supergun setup question

    Supergun makes Jamma easy, not really so much for JVS. Axun has a dual-capable supergun but that’s it. But you don’t especially need a supergun. For a JVS system like that, you have to answer a few questions yourself. Audio can go directly to an amp, it’s line level out of the rca connectors...

    JNX Rage - JAMMA Adapter for Primal Rage

    I guess your p2 buttons are the same but on the solder side. That seems more like a Pandora’s box / “chamma” or something is wired up currently. That’s not jamma standard. Jamma uses only 22/23/24 and you use a kick harness for the rest (with few notable exceptions like button 4 for Neo geo)...

    JNX Rage - JAMMA Adapter for Primal Rage

    @swampfire the jnx board does specifically remap the buttons to the layout you’re expecting. What is your wiring? Your jamma harness is wired directly to your buttons 1-2-3, right? The kicks 4-5-6 are on the cps2 kick harness? Button 4 is sometimes double-wired though jamma and the kick...

    Namco System 11 - volume potentiometer

    Well A502 is audio taper 5k ohm. I don’t see any direct replacements but if you look there are B103 (10k) with linear taper so you’d at least be able to get it functional, just with less of a functional range. Game boy advance uses that one...

    Twinkle Star Sprites: debug & dueling cakes

    If I’m stripping out the code into its own rom, I might as well add health bars and stuff too!

    Twinkle Star Sprites: debug & dueling cakes

    This post by Sudden Desu (anyone know if he's a member here?) is worth a full read-through, so I won't go into the details here. What is relevant (to me!) is that it includes two Mame cheats I was interested in trying on actual hardware, one to enable Debug options, and another to turn the debug...

    Namco System 2: Marvel Land to Valkyrie No Densetsu Conversion?

    Nope! But I did use a LOT of w27c020 to keep the weight down. Like 20 of them - probably doubled the image of it wasn’t the full 2mbit. That plus like a couple 28 pin like 27c256 or 512 might have done it. I think most were common.

    https://www.arcade-projects.com/threads/convert-tuto-namco-system-2-any-game-in-rolling-thunder-2-jap.11620/ was my starting point. Shoot me a PM if you get lost. I also used those translated roms which make it way more playable for me, here are the files...
