    About namco system 11 c431 keycus(dancing eyes)

    Personally I will always opt for least amount of code changes to ensure originally. My metric is usually "would they allow this code/system/etc to be used to set a high score?"

    Hyper Duel audio question

    It's a pretty awesome game to be sure! I think this was one of the first "expensive" boards I ever bought

    Hyper Duel audio question

    no, it's mono. Despite being a "Technosoft" game the PCB design and architecture is clearly made by Metro. And indeed they use the same mono audio system design right down the same amp heatsync, and volume pot

    Replacement CPS2 Buttons (3D Printed)

    PLA works great for these

    My screen won't stop scrolling

    I think your sync signal isn't making it from the PCB to the monitor...

    My screen won't stop scrolling

    have you tried other PCBs on this monitor? is the result the same?

    My screen won't stop scrolling

    no v-shift is completely different. v-hold = adjusting the signal for it to stop scrolling in the vertical direction v-shift = adjusting the vertical position of the image on the screen. it looks like the labels are kind of non-standard. normally it's V-POS (for Vertical Position) rather than...

    twistedsymphony's adventures in making PCBs.

    yes, progress is being made on the VG460. I have the new design complete but I do need to finish writing the code and then go over the whole schematic with a fine tooth comb before I get a prototype made. here's a sneak peek

    My screen won't stop scrolling

    Adjust the v-hold until it's scrolling as slow as you can get it, then do the same with the H-hold if one of those two knobs seems to have no effect then it's possible the pot is damaged it's also possible that you actually caused the problem somewhere else. for instance if the sync pin of your...

    Mortal Kombat 1 Audio pot type?

    I also designed 3D printed mounts to mount the Audio pot and the audio board to the main PCB: https://www.thingiverse.com/thing:3193837

    JTAG

    I ended up picking one of these up. Works quite well with the ATMISP software and code written and compiled on WinCUPL. I also picked up this pogo pin adapter from adafruit: https://www.adafruit.com/product/5434 I did this because I want to use this on some of the multis I'm developing and...

    Does Anyone Own a Gundhara PCB?

    I mean, that's essentially what I'm proposing in option 2, it would release with 9 or so games but have 16 slots.

    Does Anyone Own a Gundhara PCB?

    😂 While still technically true that the whole system multi isn't possible but I've learned enough of it's secrets to make some form of multi possible :D Glad I was wrong about that.

    So whats next on the list of multis?

    It's important to note the specific: PCB IDs PO-078A (used by Blandia) PO-079A (used by Eight Forces and Zing Zing Zip) PO-122A (used by Zombie Raid) lots of JJ Squawkers conversions out there using PO-078A and PO-079A PCBs Similarly there may be alternate revisions of these boards...
