Actually, can I ask how this works?
Is it done via .kip/sysmodule? That would lock out SX OS users though.
Or is it done via Homebrew/RCM Payload?
Or is it the holy grail, i.e. the dongle/card itself negotiates/handshakes with the Switch like a gamecart would?
If it's the last option, would it be too much to ask for a technical breakdown of the details? Similar to what you did when the cart-slot-charging problem first came up? Thanks.
I'm far from an expert on the software side of things, but @stuckpixel coded the solution and has created a pull request for libnx.

The code itself is here:

I also have an .NRO file they made me so I can test it out.
Really awesome work by @stuckpixel all around.
They were able to determine that VCC for the game card slot is directly controlled by the X1 and has nothing to do with the card slot IC. The IC only handles card communication duties.
The pin is called GcAsic Power:

If you'd like to know more I would suggest joining the ReSwitched or DragonInjector Discord servers and asking them directly.
Ah, yep. Exactly these. Thanks
Lithium Ceramic Battery gives better search results for anyone wanting to look that up.
It's a great looking technology but I can't find them for sale ANYWHERE. I'd really like to know the capacity of this little guy:

If it's over 3mAh and doesn't cost a kidney, it might be a great solution for a rechargeable DragonInjector Version 2.

Should mention for anyone wondering, we have no more than 18mm x 18mm x 2mm to fit in the battery and all required PCB components, so the battery really has to be
tiny. In addition to that, it needs to support a 10mA current draw and supply over 3V for the majority of it's life. Really narrows down the options! If I added all the time I spent looking at hundreds of pages of batteries for this project, by now I'm sure it could span a whole weekend.
