I'll probably just run an Ethernet cable into the rear of the cab. Considering how often mister is updated this is a relevant question. Another idea might be to run a usb splitter and run your powered usb hub through the rear of the cab.

I just updated my MiSTer, and can confirm that the ini settings above are no longer needed, 2 player gamepad should now work out of the box (after running the MiSTer update script).
All my cabs have ethernet cable, cause you just don't know when you will need that connection
All sorted here!
A couple things I found:
- if 5v is really out of range, the mister may power up for just a split second, then turn off (somebody may have mentioned this part before). The oled may not display anything if this happens.
- If you’re using an image from an existing mister installation, there’s a pretty strong chance that some of your configs are going to cause this to not work. Check the configs on the Irken website carefully if voltage is correct but you are still having issues.

Just ordered my 2nd DE 10, so I'm fully ready.

There is no analog video out of the DE10-nano, you can buy an expansion board that use resistors instead of a proper DAC, and that approach is limited to 18 bits of color.
I use HDMI because you also get proper audio, 24 bit color, AND I don't touch the IO ports of the DE10 at all - i.e. future proofing it. It could be that in the future, some cores will require 2 SDRAM cards, which will not be possibly with any of the other (announced) JAMMA solutions.
All required hardware, except DE10-nano and SDRAM card is included:
You all needed minus the de10 nano and ram
ATX adapter not included or needed
Does someone have spare JST VLP-02V-1 connectors? These seem to be sold out everywhere and JST has a lead time of like a year, lol. I think I have the pins for when I was making some JVS power harnesses.

It's a typo on the PCB markings, I added this on the FAQ page https://irkenlabs.com/jamma-expander/faq
The DC connector on the Expander is VH
Noooooooo.....lol, thought it looked a little smaller but went with the silkscreen, let me search again, thank you sir!
I'll be interested to see if this particular cable works. I had a right angled USB adapter on hand (pretty much the same as what you showed before) that I tried, and it wasn't quite what I wanted. I think the down facing right angle should work, but the size of the head + strain relief makes me wonder if it's too tall to fit before bumping into the PCB.I also ordered some other cables to see how fitment is since I want to put the setup in a case
got these to try out
Agree, will test it out, I havent been able to find one with a thinner/smaller profile. If I like it better than the right angle and it doesn't quite fit I will just put slightly taller standoffs maybe

I considered doing 'adapter' PCB's found on other MiSTer boards instead of cables, but with favored serviceability and logistics over aesthetics. I also have zero clue as to how much noise is radiated by the DE10, so I wanted to keep the area under it clear.
In other news, the FedEx guy will not be pleased tomorrow - all orders packed and ready for shipment. Thanks to all who placed an order this week-end!

Makes sense and simple is often times best. I hate the little microusb interconnect boards, I have broken a few of those separating the nano from the USB hub. Wish all devices came with USB-C connections though, they seem to be more robust over MicroUSB.
hahahaha....he probably wont.
Im glad to see you are getting some nice orders in. Well deserved! The JE may not have the "bells & whistles" of other similar devices, but I know and trust your designs to work as you intended. Its simple to use/set up and I know the circuit design will be solid, and well thought out.
