Hacking How to use drc-sim?

[AboodXD]

Basically, DRC-Sim is a DRC (Wii U Gamepad) Simulator.

It let you use your PC instead of your real gamepad.

You can't use this on Windows.
Only Linux, because you need to patch the kernel (or something like that).



Python 3.4 source code: https://github.com/aboood40091/drc-sim/

Guys?

Update:
I have managed to run it but then I get this error:

Traceback (most recent call last):
  File "drc-sim.py", line 43, in <module>
    MSG_S = udp_service(LOCAL_IP, PORT_MSG)
  File "drc-sim.py", line 31, in udp_service
    sock.bind((ip, port + service_addend(ip)))
OSError: [WinError 10049] The requested address is not valid in its context

Is 192.168.1.11 actually your computer's local IP address?

What I know that Usendmii shows the address 192.168.1.13....
New error:

Where did the sock.bind(('192.168.1.13', 80)) come from? PORT_VID isn't 80.

 

[AboodXD]

Where did the sock.bind(('192.168.1.13', 80)) come from? PORT_VID isn't 80.

I saw this IP and port in Usendmii, I said to myself: "Maybe if I used those, it might work!", but then...
oh by the way:

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

 

[bobmcjr]

Reset the ports to their original values. Open command prompt and type ipconfig, and replace 192.168.1.13 with your IPv4 address.

192.168.1.13 IS already the IPv4 address!?!? lol
The ports original value was: port + service_addend(ip)

[bobmcjr]

Not sure what the issue is there. For some reason python is treating (854,480) and get_size() as single arguments. I don't use python normally so I have no idea.

I have looked into this code some time ago.

My conclution is that this code does not handle the pairing between Wii U and PC.

You have to do pairing with a modified wpa_supplicant in linux. But I don't know how.

You can find a tutorial for pairing between PC and Gamepad in the documentation of libdrc.

 

[Kinnay]

Eh, did you modify H264Decoder.py?

The line that's wrong is different on the bitbucket.

On the bitbucket it's: def __init__(s, (in_x, in_y), (out_x, out_y)):
But in your code it's def __init__(s, in_x, in_y, out_x, out_y):

Change it back to the original.

No Windows?

OK..?! How am I going to find that?

Update:
I don't get that(out_x, out_y) error anymore, what I did was to change:

pygame.display.get_surface().get_size())

to

pygame.display.get_surface().get_size(), None, None)

Didn't expect that to work but it did.
But now I have to download Visual Studio since Python needs it.
Note: I tried MinGW, but it didn't work...

Run it on Python 2 instead of Python 3. If you're randomly changing things without knowing what you're doing you're most likely just going to get more errors or unintended behavior, even if it doesn't seem like that at first.

OK.

Update:
I've downloaded Visual Studio 2010 Express(the version that it's needed) on my Laptop(Windows 10) and the installation failed...
I downloaded and installed Visual Studio 2013 Express instead, then I used "SET VS100COMNTOOLS=%VS120COMNTOOLS%" command line but Python still says I need Visual Studio 2010... I found this method in Stackoverflow and I've followed it very carefully but it's not working..

©2013 Mema Haxx, ©2015 AboodXD. This tool was made by Mema Haxx, it's used to stream the Wii U gamepad signal from the Wii U console to the PC, so you can use your PC as a "game controller" instead of the Wii U gamepad. It was modified by AboodXD to work with Python 3.4. This is really useful, if your Wii U gamepad is broken, you can use your PC instead.

But... you don't have it working?

 

[AboodXD]

Well, the only error I have is just not having Visual Studio 2010, if I had it, I'm pretty sure it would have worked.
Almost(if not all) all errors listed here are caused by my computer settings... and IP address.

I'm not super familiar with Python to know the differences between things working on 2.x and 3.x, but what did you change from Mema Hexx's version to get it to "probably work" on 3.4?

The only differences I see are:
-changed "import construct" to "from construct import *"
-removed the parenthesis from print statements
-changed "def resize_output(s, (x, y)):" to "def resize_output(s, x, y):" (which as Kinnay stated about your change in H264Decoder.py, that's probably going to cause issues)

Are these things the necessary components to get things from 2.x to work on 3.4?

That thing.... I don't know why did I put it there...

-removed the parenthesis from print statements

This is so important, so you wont get a SyntaxError.

-changed "def resize_output(s, (x, y)):" to "def resize_output(s, x, y):" (which as Kinnay stated about your change in H264Decoder.py, that's probably going to cause issues)

I don't know how to deal with this, but I'm trying to figure out how to make it work in Python 3.4.

Yes, we don't need to change anything else, except for LOCAL_IP.

 

[Kinnay]

It's fine to remove the parentheses, but you can't just pass None as arguments. One possible solution would be to use the * operator to pass x and y as separate arguments.

This wont work in windows. It requires your Wii-U to be paired with your computer (your computer then acts as the Wii-U gamepad). The IP in the code is there to host the server that listens for communications from your Wii-U. To get this to work you will need a Linux install with a patched kernel and the right WiFi USB device.
