DragonMMC replaces the stock MicroSD and NAND boards, and adds a slide switch to choose between up to 3 MicroSD cards/NAND modules. This slide switch protrudes slightly from the original MicroSD card slot, while a replacement kickstand houses 3 MicroSD card slots. Installation does not require soldering, but will require some disassembly of your Switch. All required tools will be included. Removal of the heat shield is currently required. Addons for the DMMC are planned, including fully internal Bluetooth audio streaming, and you can easily make your own thanks to the expansion connector and solderless USB passthrough. (Note that the DMMC itself has no USB capabilities and only passes the USB lines to the expansion connector.)

DragonMMC is modular, with 3 NAND module slots available. An adapter module for the OEM NAND is included. Extra NAND modules of 64GB and 256GB will be available on the web store. The modules are snap-in and do not require soldering. An MCU handles NAND module and MicroSD card detection, as well as safe switching. The slide switch can be moved at any time to change the desired NAND module and MicroSD card. A restart or power cycle of the console will be required to enact the changes. If the selected MicroSD slot or NAND module is empty, DragonMMC will look for the next populated slot and enable it instead.

DragonMMC will be based on the ESP32-PICO microcontroller. More info to come soon!

Wouldn't the switch overheat without the heatsink?

The heatsink plate doesn't really do much compared to the actual heatsink block and the heatpipe. In my testing, during heavy gaming I didn't see more than a 2 degree increase in SoC temperature versus having the heat shield installed. That said, I do not overclock my console.

In any case, I'm going to be looking at getting a custom heat shield made that still allows room for DragonMMC.

To be honest, I don't think the metalshield really do any "heatsinking" at all. Maybe minor, but not much.

Im sooooooo impressed. Damn, im really impressed.
Im speachless.

Good luck on getting everything to work, im excited for the final product.

For what? We don't include, link to, provide instructions for or support any particular payload besides our chainloader, and this goes double for anything piracy related. You cannot commit piracy with any of my projects on their own, and we actively discourage piracy and restrict discussion of it within our circles. I buy the games I want to play and the software I want to use, and I think everyone should do the same. If you decide to use a certain CFW and certain tools that allow you to commit piracy, you need to find them on your own and learn how to use them yourself, and that's a choice you make on your own.

At it's core, DragonMMC is designed to let you expand the utility of your console by making it easier to run different environments like Android or Linux. The actual concept came about because I wanted to run Android on my console and became frustrated with all the steps involved and the performance loss from running off SD. Payload injection was actually an afterthought, and was added as a "why not" feature, since my choice of MCU already supported it.

EDIT: I should mention that a bunch of people I know who had gotten bored of their Switch have had their interest reinvigorated by the the thought of dead-simple Android dual-booting. Rekindled interest inevitably leads to more game or hardware sales for Ninty.

If you guys want any help feel free to try and get into contact, I might be able to lend a hand.

 

[fvig2001]

Hope this works well, I might order for my 2 switches. Hopefully the NAND modules can really be replaced with SD cards. Hopefully 64gb SD cards are fast enough since some of my games run well only on NAND.

I've been following this whole journey on your discord with the dragon injector and damn, this new project is incredible!

Hey I read your article so I'm assuming this is only covering the patchable units right?

Not sure exactly what you mean, but to use the payload injecting feature of DragonMMC a non-iPatched console is required.

Sorry I had wrote it wrong I mean this is for the gen1 units that are exploitable.

Yes exactly, since there's no open-source method for newer generations yet.

 

[eyeliner]

I love people that think outside the box.

Great idea that I truly hope it succeeds. I also hope it is installable by a numb skull like me.

Ive already broken the sd reader connector on two switches while trying to replace a broken reader but screw it, I'm trying this anyway

Sorry to hear that, the OEM reader is a pretty bad design. It's only held in by one screw and so twists the connector back and forth upon SD removal/insertion, eventually causing pins to break off.

If you have anyone locally that can do tiny repairs, I have the part number of that connector if you'd like it.

How much/ do you have a link?

MOLEX 5042481610 is the part number for the motherboard side SD B2B connector. You can get 10 of them for about $10 on AliExpress.

Actually, it might be the MOLEX 5042081610. One of them is switch side and the other is SD side. Let me see if I can figure out which is which.

Got it, 5042081610 is the motherboard side.
