So if I wanted to follow this guide I would need to flash something like Mattytrogs loader so I could use more than one payload?

You could, but I think multiloader is not really needed. You can first flash the dongle to send the memloader payload one time, then flash it back to hekate.

I put the zip files for memloader v2 and hekate 4 UF2's below.

Awesome. I wish I would have seen this before I bought my jig seperate, or this would be an extra no brainer for the $15 difference. I have that link opened up though and want to be grabbing one of these things bad. I could grab a Usb C to USB C cable at 6 inches from Monoprice, and push payloads from the my phone, but I like the simplicity of this device much more.

Yes, it's nice to be able to swap payloads and change firmwares in a snap. If you have a cable, the V1 version is cheaper but does not have USB C.

Just fyi my jigs wire kept being pushed up into itself, I tried pushing it down, but I think I bent the top of it a little, luckily I got it working long enough to do autorcm. Other than that the dongle works great, been using it a couple times now so I am not tethered to my computer, so much faster. But I mean if I need to use different payloads it just makes more sense to use tegrasmash because I have to connect something to my computer anyway.

Ok, thanks for the feedback on the jig wire. I'll start gluing them. I don't think the wire could move if it was still bent down over the front edge - at least mine don't move here. Could it be that the front part that hooks down got bent and now it is floating free?

The jig I had purchased worked last night flawlessly, and not at all today. So I just went ahead and ordered v2. My jig was bridging 10 and 7, and I've been messing with it for the last 2 hours. Yea, im done lol.

Heres a photo of it pushed down as much as I can't without shoving something in the top.

Yep, the wire got bent up - must have gotten hooked on something. The wire bend is enclosed in the body of the case - try sticking a toothpick in there to push it forward, then bend the two leads down so they hook over the front.

Thanks for the order, I am printing a case for it now! I'll throw in an extra jig just to ward off evil jig spirits. :) Mine bridge 1 & 10, not that it makes any difference over 7 & 10, just mentioning it.

New plan! I can drip some SLA resin into the cavity and then cure it - that should lock the wire in since it will be a piece of the solid body at that point.

PM me your address, I'll send ya a new one of the latest design with the resin backfill as well. You can be my beta tester.

I feel the same way, I think this dongle is the perfect solution for me.

I have an SX pro, but I've had the capacitors die on me while my Switch was sitting in AutoRCM, and having to find somewhere to charge your dongle at is a pain. So I don't want another Chinese dongle which just has another capacitor that will die on me at the worst time.

And I don't want one of those $15 ones that come with an extremely cheap lithium battery, I don't feel it's any more reliable than a capacitor at all. And I've had a few orders from China blocked during shipping due to having a lithium battery too.

A dongle powered by a CR2032 is just perfect, I can very easily carry a spare battery for that. But I can't solder, and the solderless solutions I saw at best were a frankenstein setup, using a wire to connect a battery holder to a trinket, then another wire to connect to USB-C. At that point, I might as well just carry a single cable to connect my phone to my Switch, or a cable to charge my SX pro when the capacitors die, and a powerbank (for when my phone/SXpro dies).

But this thing... a dongle with BOTH a CR2032 and a built-in USB-C connector, no cables required to be brought along at all! I'd buy it now but I'm just holding out for a joycon colored case, which would make it perfect for me. :P

I have looked into making joycon colored cases, I'm not sure it's practical for SLA, it would be a custom pigment mix and rather difficult to match and produce reliably.

I got everything today, holy crap. So two small issues that I am for sure certain are on me. I had a CR2032 that I put in to the dongle, but it didn't turn on. I also used one of the jigs and it didn't work, but the second time around I pressed the Switch button combination differently for the second jig and it worked just fine, so I will retest the first jig. Also, wow is the build quality is fairly high for being a homemade 3D printed part. Not to slag the other jig I purchased, because the people behind it were extremely nice, but this one does seem to hold up a bit better.

Very happy, and I will let you know when I can get a proper battery in to this thing what happens. :D

Edit: 1st jig and second battery work flawlessly. Now to get the ReiNX bootloader on here before my trip tomorrow.

Edit 2: YOU RICK ROLLED ME?!?!? IN 2018?!?!

Ahh, batteries - I wish I could include one because old batteries give lots of people problems. Glad you got it sorted, and everything is working well for you now.

And congratulations! You are the first person to discover the (not so) hidden rickroll! Bahahahaa!! You deserve a prize, let me think about it and get back to you!

To keep you up to date though, the ReiNX loader file you gave doesn't work. I found the latest Hekate you posted, and modified the ini. Or, I tried to, someone over at ReiNX gave me her ini and it is loading flawlessly now.

It's probably just a version mismatch on ReiNX, the loader payload has not been updated in a while and ReiNX seems to mod their payload every time - why that's necessary, I have no idea. You can update payload with the UF2 Splicer to the new payload, or I'll do it when I get a chance.

Ok, here's a payload for ReiNX 1.7!

Oh awesome. Someone over at ReiNX gave me a Hekate ini cause I couldn't find the software to do it. xD Thank you :D.
