[POC] 3DS Websocket server demo for homebrew utilities

Testers needed. This is mainly a proof of concept for developers, but I would like others to test it too so I can better refine it with more browser/system support. Let me know if you have difficulties/bugs.

This technology can allow developers to make applications in web browsers that can interface with the 3DS console. A lot of possibilities.

@MarcusD and @zaksabeast I would've pinged you guys about this in discord server, but I think some moralfag banned me.

 

Not exactly, not without homemenu hacks. Currently it's up to the homebrew itself to supply code to connect to browser. This demo app should serve as an example for devs.

 

Does it just keep giving that over and over or does it eventually work? Because it will occasionally fail, but should keep retrying.

 

Thanks, that gives me a better idea of what's going on. I think I might know what it is.

 

It currently runs as a websocket server and not a client, but yeah you could use it as a websocket client too with slight changes. I was thinking about making a agar.io client for 3ds, but have other things to do atm.

 

This is only communication between your browser and the 3DS, nothing more. So nothing is stored on another server or going through any other server. The 3DS console is the websocket server and the browser is connecting to it.

My demo is hosted via github pages, so anyone can make their own too. Only problem is that it currently doesn't have SSL support. Or rather, most popular browsers reject self-signed certs over secured websocket, so I didn't bother figuring it out.

 

Sure, the code is already there for transferring images. Instead of just copying it to the framebuffer, you could save it to file. Likewise simple for sending from 3DS to browser.

At the moment, any binary data of the right size is considered an image to copy to framebuffer:
https://github.com/Cruel/websock3ds/blob/dcdb2036acb661fe55f13aeb50f92302576fc788/src/main.c#L97

But currently the browser client doesn't do anything with binary data sent to it since the title data the 3DS sends to it atm is a JSON string:
https://github.com/Cruel/websock3ds/blob/aec054c3c08a02d49fb6ad2da6e2122e6f1cd4ac/js/main.js#L33

EDIT: there are some security issues with browsers saving to disk, but it's possible you just need to add a button or something to trigger the saving. Guess it could be useful to show how to do that if anyone wants it.
