This is really cool!
But, with the ability to use the same controllers on PC, with a bigger screen, cheats, and less input lag...
This doesn't seem too practical, considering you need a PC to use multiplayer...
But, if you could get this to work on download play, you'd have some amazing homebrew there.

I actually requested it before.

This is cool and all, but on my NES titles, you can just switch between 1 and 2 player by pressing LR then Y

But I guess you can say this is almost like a "Switch" since a 3ds is now a portable "NES Console" within requirements.

This is pretty neat!

But why not just use two 3DS as input?

 

[FateForWindows]

I'm using it with InputRedirection with an Xbox One controller and no xpadder and I'm not having issues.

 

[ShadowOne333]

Nice to see that you went forward with your idea and made it to the end
One thing though, why don't simply add a Pull request to the official app for this modification of the source code?
Would make handling further commits much easier.

The point is to just use a single 3DS console like an NES portable that supports 2 controllers.
Sorry, but two 3DS'es = Two screens.

Two 3DS'es = Two screens.

But it requires using a PC to handle the actual inputs, thus defeating the portability aspect.

I just want an emu that supports local multiplayer with 2 3DS's. Someone oughta make that happen someday.

I haven't tested it yet but can one player use the 3ds as gamepad and the other use the gamepad through the PC?

Also if the input redirection can be used with a raspberry pi, it could be more portable

Yes.

Well let's just say that I have this friend who has a 3ds, but it's not hacked like mine or yours is.
Not everyone you want to play multilayer with isn't going to have a 3ds with a cfw on it. So having the use to use controllers is perfect for each persons use.

I also was thinking this gonna be like linking 2 3DS to play together, would be awesome haha
But this is pretty good actually! Nice work!

 

[OfficialBrony]

I mean, @Robz8, this is pretty cool. Why settle in for a NES Mini, when we can use your project, and then stream the video to your computer? I mean, not every one is going to have frame-perfect speeds, but games are still playable for me when I stream and it beats the 2 foot cord Nintendo supplied for the NES controller.
EDIT: Not everyone will be able to do this if you don't have a N3DS/XL
