    Axun Workshop - JVS / JAMMA Control-Box(CBOX) SuperGun

    Simplest, but a bit annoying method of solving that for you might be to just buy a jamma fingerbord, solder a hirose connector on one side and use that between the supergun and pcb :)

    Can anyone tell me if they've had positive experiences with Yaton?

    Have ordered parts and games, have received what was being sold. Also, back in the days (like 15ish years ago) he used to sell MVS carts for dirt cheap that looked like they had been filled with volcano ash or something. Still super happy with those as well though.

    Axun Workshop - JAMMA Extractor (JAMMA Capture/Streaming Adapter)

    I’m a little bit confused. I thought CV1000 was just using jamma standard amplified mono, so wouldnt other pcbs also be affected? edit: Testing on SDOJ is one hell of a nice flex btw :D Thats like a 6000$+ pcb

    Haha damn, thats a nice cv1000 collection :)

    Axun Workshop - JAMMA Extractor (JAMMA Capture/Streaming Adapter)

    Should be same for any mono jamma pcb. Cave doesnt do anything special, its amplified mono like jamma standard. Havent tried my axun splitter yet. Should do that soon.

    Axun Workshop - JAMMA Extractor (JAMMA Capture/Streaming Adapter)

    Probably good to do some more testing with different monitors before you start swapping things. I guess there’s a possibility youll want different values for different monitor impedances?

    Awesome, my order is on that list. Looking forward to new unit :)

    Will this be sent out to everyone who have received one automatically? Awesome if so.

    Axun Workshop - JAMMA Extractor (JAMMA Capture/Streaming Adapter)

    That's an interesting point. For 4K capture, then USB3HDCAP is definitely not the way to go. I thought it only supported 1080p :) For retro stuff though, that doesn't really matter much though. OSSC is just doing linemultiplication and since it's digitized you can go ahead and do further...

    Axun Workshop - JAMMA Extractor (JAMMA Capture/Streaming Adapter)

    I haven't seen that much of a difference between capture cards in terms of quality when testing various ones. Some have better compatibility on weird resolutions. In general I've been very happy with USB3HDCAP for capturing stuff. The thing that I've seen the biggest difference is how you scale...

    CV1000 JTAG

    I don’t have that, but could ask nicely if I could borrow one again (did so when getting 1cc on it)

    CV1000 JTAG

    Nope. Would have to be software based, or by writing a core to the FPGA I guess. Either way, I don't think any game supports it (or even has it mounted).

    CV1000 JTAG

    If anything, this makes it easier to dump potential undumped versions. Regarding double checking, yes you should look out for conversions but that was already the case before this. Considering I didnt have to spend much time at all getting this working, I would be extremely surprised if more...

    CV1000 JTAG

    Nha, this is not related to that. It's more that I literally don't know how to call set signal CE2A out 1 from the urjtag python API, so I have to do it when initializing/detecting the SH3 in urjtag instead (see repo for U2 writes) This is what's available in the python API: >>> dir(chain)...

    CV1000 JTAG

    Figured out why I had issues doing U2 writes. Needed to configure the CE2A pin of SH-3 (which is connected to U2 WP) to be active high to get things working reliably. Looks like it's input HiZ as default or something. For some reason, I'm having a hard time doing that in Python urjtag bindings...

    CV1000 JTAG

    If I read the flash datasheet correctly, it's the responsibility of the software using it to handle bad blocks replacement. Haven't looked at how cv1000 games do it

    CV1000 JTAG

    Minor update, made it possible to read the U2 bad block table easier. This is just parsing the table at page 0. At least on my mushi board, the bad blocks seem to just contain 0x00. $ sudo python3 K9F1G08U0M_JTAG.py bad_blocks Starting Resetting Flash Reading page 0 Found bad blocks: [328, 607]...

    CV1000 JTAG

    Yeah, I do agree that reading U4 through urjtag should be safe, assuming everything is hooked up correctly. The thing I could be worried about would more be something like someone not knowing what they're doing and accidentally shorting VCC Target and GND, or doing something else that's not...

    Betsu Betsu: Open source Arcade Audio/Video splitter for capture/streaming

    Haha yeah, it definitely doesn't handle that well. It shakes all over the place for me View: https://www.youtube.com/watch?v=cMSzxQjj6ZE

    CV1000 JTAG

    I think this project is more or less complete for now, but I'll probably come back to it later. I'm gonna double check some stuff and clean up the docs, but otherwise the big thing left is U2 writes and regarding that The more I think about it, I think this might actually be an interesting way...
