    How can you possibly re-create a board if you don't have physical access to one.. I much prefer jotegos, furrtek and others approach that does it IC by IC.

    Video about my new crimping machine premieres today at 11AM EST.

    I don't have space for it, I have no need for it, but after looking at the video I want one anyway :)

    Name for JVS2JAMMA board

    As you may have noticed, I haven't had tri-sync helpers in stock for a while and I likely won't restock. There is however a new Jammafier 2.0 in the works, that has the tri-sync helper stuff embedded, making for a more compact solution for Tri-sync users. You can switch between untouched...

    Multimeter recommendations?

    Mostly convenience and speed for basic checking of stuff. Speed is both in regards to actual measurements, and always being able to just grab the probes and not worry about batteries, placing it somewhere on my messy desk etc. Also it has a large screen, which makes reading measurements...

    Multimeter recommendations?

    If you have a workbench, I would highly recommend getting a bench meter - it's a bit above your budget, but I have nothing bad to say about the Siglent SDM3055. You may be able to find a used HP/Agilent/Keysight bench meter that's within budget. For portable stuff and messing with cab power...

    @Devil_mish sounds like a hardware error, a little odd, as the factory init/automated QA stuff has a test for all switches, including that one. Send me a pm/email and we'll get it sorted.

    I'm happy that you got something working, but direct_video really is the way to go - if that doesn't work, something else is wrong.. Does your cab work OK with other PCBs, could it be your monitor needs some adjusting?

    The Expander has no influence over tate/non-tate, but just rotating the mister menus should do the trick? https://github.com/MiSTer-devel/Main_MiSTer/wiki/Configuration-Files#osd_rotate

    @Devil_mish are your MiSTer settings the same as described here? https://irkenlabs.com/jamma-expander/mister-installation If you have funny video timings/modes, maybe direct_video is not enabled?

    A bit of overvoltage should not kill anything, JAMMA backwards otoh will fry stuff.. Let me know, I may implement a debug function to identify cabinet (and rule out Expander) issues when it comes to input.

    Maybe double check wiring and that the expander is not set to chamma? Having a squint at the wiring diagram https://wiki.arcadeotaku.com/images/e/eb/Konami_windy.pdf it looks like it uses the 'bottom' GND pins for stuff like coin and input, while the top GND pins are used for power.

    If video is the issue - just be sure to set SyncGuard to correspond with your cab (and now I see that it's not documented on the website, as I was going to paste a link :)) If x68k core outputs 31k but your monitor is 15/25k, it's not much the expander can do..

    No idea, does it have special requirements?

    I guess the gamepad mode is not used a whole lot, but one user found a bug where the setting didn't survive a restart. Update with fix available here: https://irkenlabs.com/jamma-expander/firmware-update
