    WTB: Sega Naomi Power Supply / Sun Power Supply

    Bit late to the conversation, sounds like you have a solution. But I went pico-atx awhile back. Just needs a good 12v and everything works great. Very convenient when working on my bench setup.

    How to Net-boot NAOMI/Tri-Force/Chihiro Using Pi-Force Tools

    What is the make of LCD (there are a few out there other than the original adafruit one) and how well is it seated in the GPIO? Also, anything showing as an error if you hook up the HDMI display?

    How to Net-boot NAOMI/Tri-Force/Chihiro Using Pi-Force Tools

    I took a look at @Kidkaos's setup and the issue was the micro sd card adapter. The Raspberry Pi simply wasn't posting. Using a different micro sd to sd card adapter solved the issue. The piforce-tools download link and instructions on the git-repo are still good (just built a fresh install last...

    Naomi filter board JVS connector replacement?

    Ditto for more expensive things, but in this case it's just a few bucks. Less than a sandwich.

    Naomi filter board JVS connector replacement?

    Yeah, I'm willing to pay a few dollars extra to let someone else risk not getting the item in a timely manor if at all. Fool me seven or eight times, shame on me still I guess.

    Cheaper, but in China. Limiting search to north america.

    Naomi filter board JVS connector replacement?

    That's kind of what I'm looking for. A specific part with the tabs/pins in the right position/orientation. Would hate to order a part and have it not quite fit... For reference: have a few boards with similar damage. Thinking this, but not sure: https://www.ebay.com/itm/353309527530

    Naomi filter board JVS connector replacement?

    I have a filter board with a broken JVS connector. Anyone know off hand which USB header would be a drop in replacement part?

    IREM BomberMan World no audio diagnostics help request. YM2151?

    Thanks to both you and @ack for the info, will try to recheck the audio ROMs when I can (worked some 18 hour days last week, so not doing anything this weekend).

    IREM BomberMan World no audio diagnostics help request. YM2151?

    ROM set is from @Hammy. Late work night, not remembering the EPROMs used... but should have been 27c1001s.

    Taito F3 OSSC problems

    I've not seen one in some time, but then I've not been looking very hard. Tricky thing to watch for on the auction sites, thinking the cheap ones would be the ones the seller cant identify. I've a couple RetroTink2x units. The original and the pro. I didn't use them for this because I'd have to...

    IREM BomberMan World no audio diagnostics help request. YM2151?

    Still working on this... code release week, so work is going to be a distraction. Took a look at the YM2151 under a thermal camera. Nothing too outrageous. Couldn't find any other hot spots on the board.

    How to Net-boot NAOMI/Tri-Force/Chihiro Using Pi-Force Tools

    Which LEDs are lit (and which colors) on the Pi?

    How to Net-boot NAOMI/Tri-Force/Chihiro Using Pi-Force Tools

    Anything showing from the pi’s hdmi output that would indicate a software or serial communication failure? If I had it here I could swap out hardware to narrow down the issue. Can be sure I could find the problem or fix it but we can leave that as an option if nothing else works.

    How to Net-boot NAOMI/Tri-Force/Chihiro Using Pi-Force Tools

    With it powered on, gently twist the potentiometer in both directions with a screwdriver to see what happens. Not seen that variant of the LCD so not sure which way would be which. On mine, there is a small “sweet spot” to find where the contrast correctly shows the characters. Note it takes a...

    How to Net-boot NAOMI/Tri-Force/Chihiro Using Pi-Force Tools

    What you’re describing is what it would look like if the contrast was off. Can you post a picture? Example: mine with the contrast potentiometer cranked all the way to the left.

    How to Net-boot NAOMI/Tri-Force/Chihiro Using Pi-Force Tools

    Revision F or higher of the original BIOS versions will work with net-booting, or the multi-bios. On the ebays you can get the multi-region BIOS for ~10$. I'll keep looking, but I don't think I have an appropriate EPROM handy, but I'll keep looking. All of that being said, the Pi and LCD should...

    How to Net-boot NAOMI/Tri-Force/Chihiro Using Pi-Force Tools

    I'd have to see what EPROMs I have around, but let's diagnose things a bit first. Any reason you're after revision H vs a mutli-region BIOS? Can you post pictures of your setup, including the dip switches and the LCD?
