• The Internet Browser uses specialized JavaScript to obtain button states of the GamePad.
• The button states are converted to JSON and sent to UsendMii using WebSocket protocol. POST request are used for version before 4.0.0.
• When received, UsendMii will simulate keystrokes, mouse motions, or button clicks.

Nice

 

[Crayon2000]

UsendMii 0.3.0 is now available.

Changes:

• Works with New Nintendo 3DS.
• Showing all available IPv4 addresses.
• Improved web menu.
• Updated Bootstrap to version 3.3.6.

Here is my video to announce the new version:

 

[Deleted member 373223]

can we use it for 5.5.0+?

 

[EpicLPer]

Okay, one bug: The "L"-Button actually goes a page back and thus won't work as a button.

 

[Crayon2000]

Yes, to have a faster button state transfer it's best to have 4.0.0 and up.

Okay, one bug: The "L"-Button actually goes a page back and thus won't work as a button.

Simply open the PC Input page in a new tab and close all other tabs. That's the trick I'm showing in this video at 1:05

First of all: Amazing work glad to see this project alive

I tried streaming 2 movies to the WiiU but one of them didn't work.

Working Moive: MP4, 1.44GB, Lenght: 1h30m, 1920x1080, bitrate 2176kbps, 23FPS

Not Working Movie: MP4, 2.15GB, Lenght: 2h30m, 1920x800, bitrate 2063 kbps 23FPS

audio is pretty much the same.

The error says something like this: Could not load video, Reload?


Possible subtitle support in the future ?

Thanks M*

• Video Codec: MP4, M3U8+TS(HTTPLiveStreaming) (Some videos may not be playable.)
  
  
• Audio Codec: AAC - ISO/IEC 14496-3 MPEG-4 AAC (Some audio may not be playable.)

Have you done any latency testing?
And have you looked into implementing direct connection with the PC and the gamepad? I know some people made an opensource library for Linux in C that did this, but no update on that for a few years.

 

[Crayon2000]

Hello, I'm able to go around 10 ms. Try it for yourself, start UsendMii by adding the -d switch. You should see the average time to get the button states.

And have you looked into implementing direct connection with the PC and the gamepad? I know some people made an opensource library for Linux in C that did this, but no update on that for a few years.

This is way too complicated for me. The guys from libdrc were on a good start but I think the problem was to keep it sync for a long time. Plus the major problem was that it was only working on Linux due to the obfuscated version of Wi-Fi 802.11n and WPA2 AES-CCMP.

So it would be difficult adding subtitle support ?

It would only work with certain wifi adapters with modified drivers. I think that's too much work for little benefit.
Nice for some proof of concept demonstrations but nothing else.

 

[Crayon2000]

@Majk there is an HTML 5 track tag for supporting subtitles with the .vtt extension (WebVTT). The Nintendo Internet Browser support it (not tested yet). I think it could be possible to add it. I'm going to look into it.

may i ask.. which version of vjoy do you use to work with the game pad?

 

[Crayon2000]

UsendMii 0.3.0 will try to pick the one installed in the vJoy folder.

 

[JR0DGamerz]

Very bad, Too glitchy, doesn't control well.

 

[Jahruze]

oh ok.. i just found the problem..it doesn't work well with windows 10 vjoy :/

 

[narutonic]

Very good works just one problem.
If we push the button Y then the A it goes on the main page of the browser on the wii u...

A way to avoid that ? I dont want to remap the button in another place because its a bit unconfortable in PPSSPP...

 

[BurningDesire]

Not only is this amazing it is for mac! I LOVE YOU DUDE. #RespectTheMacintosh

 

[Crayon2000]

oh ok.. i just found the problem..it doesn't work well with windows 10 vjoy :/

@Jahruze, what do you mean! vJoy does not work well in Windows 10 or UsendMii does not work well with latest version of vJoy installed on windows 10?

Very good works just one problem.

Sadly the only trick is to remove all your Bookmarks.
