    Supergun powered by USB-C

    What I would like to do and I’ve been collecting bits and pieces for is an all in one supergun for JAMMA and JVS - running off USB-C The idea would be for it to be a DIY design. I’ve been working on ideas to fit it all into a housing and connecting everything but my thinking is ZY12PDN or...

    Supergun powered by USB-C

    These are what I used - they support a full 5A at 20v I bought several so I could use them in consoles etc as well. They also have a trimpot so you can increase if required https://a.aliexpress.com/_msAzy6u

    Supergun powered by USB-C

    I feel the same way, but there’s always the mantra of If it ain’t broke, don’t fix it Existing supergun designs are tested, cost effective and power supplies are the same. Redesigning takes time and effort and people may not be willing to spend the extra and you’re already getting a return on...

    Here is where I tried this setup on a few boards to see if it would even work. It did

    Supergun powered by USB-C

    I was thinking this but then came to the conclusion that if it’s more expensive than a traditional arcade PSU (quality USB-C power supplies aren’t cheap) then it was not really going to work Fully integrated into the board would be the only way for it to make sense and even then it’s still...

    Supergun powered by USB-C

    I’m in exactly the same position but also have no ability to design or modify a design for a PCB I can build it and maybe diagnose it if it doesn’t work but that’s as far as I can go lol

    Supergun powered by USB-C

    The maximum current output of that power supply is 2.4A on 5v - enough for MVS, not enough for CPS2/3 or S16 It will also be reduced if you’re using 2 voltages at once

    Supergun powered by USB-C

    I have considered building and have prototyped a USB-C arcade power supply. Have a molex or similar output for connection to a supergun with USB-C input But this seemed like a waste when it would cost more than a normal arcade PSU to build and have more limited application A proper USB-C...

    Supergun powered by USB-C

    You need to add extra space for the trigger board and buck converters Ideally you would move all of these components onto the main PCB itself and have a single USB-C input but this is what would require a lot more work

    Supergun powered by USB-C

    If you’re using 2 trigger boards you would need to use 2 separate power supplies. A USB-C PSU won’t output 2 voltages simultaneously You also have the issue that 12v is part of the PD standard but not all power supplies have it. Most do 5v and 20v only as these are the standard voltages used by...

    Supergun powered by USB-C

    No need. As long as you use a sufficient power supply it will work fine and the output current will adjust automatically I have tested quite a few boards with a 100W USB-C power supply and haven’t found anything yet that wouldn’t boot Boards that normally need 5.1v etc need more current but...

    Supergun powered by USB-C

    I guess it doesn’t exist because no one with the skills has made it. Existing power supplies work fine and to support USB-C takes quite a few extra components and modifications to existing designs It would require a lot of work to redesign it and would cost more to build, and it’s unlikely...

    Darksoft CPS2 Trouble in New Zealand

    Have you tried running the test ROMs? That might tell us if it’s an issue with level shifters (unlikely on a new kit but not impossible)

    Darksoft CPS2 Trouble in New Zealand

    The interconnect board between the multi kit could have caused the black screen but if it runs on decrypted ROMs it’s fine The smaller ROM board is the main program section and it’s both booting and showing the title screen text correctly (this is stored in the main program section as part of...

    Darksoft CPS2 Trouble in New Zealand

    Black screen is caused by an issue with encryption keys. The program code is being read but it can’t boot I’m not sure if you said you got past that part or you’re currently running decrypted games, but that issue was probably related to power - the resistor is just there to help smooth out a...

    DARKSOFT What Donor Board to use for the CPS1 Multi

    Where are you located? There were a couple of eBay sellers but I’m not sure if they have any remaining. CandyCabClub run by @djsheep sells them with the multi and may still have some but shipping will be from Australia
