Guitar Hero3 wii controller in Ubuntu

[djuniah]

I just picked up GH3 for my Wii and I'm loving the game. I also play Frets on Fire on my ubuntu machine quite frequently and I thought it would be a SIMPLE matter to connect my GH3 controller to my PC via bluetooth and jam out. Boy was I wrong! I have everything set up for the wii remote control and it works splendidly, BUT when I try to connect my wiimote with the GH3 adapter added on I get the following error:

I also noticed that even on the wii, the GH3 controller does NOT work until you put the disk in and click on it in the menu. This initializes a system update and then once that is done, the Guitar can control the cursor in the menu. This leads me to believe that its using some new type of interface with the wii than we are used to seeing. So, there has to be a way to get this working with WMD. I just havent figured it out yet. Has anyone else tried this? I'm going to start poking around in the python files to see what the cause is.

Also, if i use

sudo hidd --search

and

sudo hcidump -X

with JUST the wiimote, i get the expected results, but as soon as i plug in the GH adapter it spat out the following lines then stopped responding to key presses (even if i removed the GH adapter).

> ACL data: handle 6 flags 0x02 dlen 12

      0000: a1 20 00 00 02 00 00 57                           . .....W

can anyone with a little more experience shed some light on this issue?

Thanks,
DJuniah

wow. that's really strange... my guess is that redoctane knew some people were gonna try it on the pc and did something to the guitar that would change the signal. but it's not like it's a permanent road-block right!

[markmark]

In "Input.py" find:

  def process_stats( s ):
    pass

  def process_bat( b ):
    pass

And change it so it reads:

  def process_stats( self, s ):
    pass

  def process_bat( self, b ):
    pass

Alternatively process_stats and process_bat don't do anything, so you could just comment out any calls to them.

I'm planning on getting GH3 for my Wii sometime soon and I want to use it in FoF, so hopefully someone will get all this working.

Actually I just looked at the svn version of wmd and notice that Input.py has been updated a fair bit from the version I downloaded (https://svn.forthewiin.org/wmd/trunk...imote/Input.py)

Might be worth checking out the lastest version from SVN.

Ok, getting a little further now. It is at least seeing that there is a peripheral attached but it doesent seem to know what to do with it. Heres the console output:

Did you check out an entire new version of the whole program from SVN? Or just grab that one file. I know my post wasn't very clear, but you'll have to use subversion to check out everything.

[djuniah]

yes i made sure to grab everything and do a full checkout, but no luck. I did see the new file that looks like it handles controller add-ons though. I'm guessing what i seek has something to do with a definition that needs to be added to that.

[markmark]

The error is saying ext_device_name isn't defined but they are trying to check the value of it.

Perhaps change:

 def __init__( self, ev, wmmode ):
    self.ev = ev
    self.wmmode = wmmode

to read

 def __init__( self, ev, wmmode ):
    self.ev = ev
    self.wmmode = wmmode
    self.ext_device_name = ""

That should make sure that ext_device_name is set to something when the object is created (although I thought what they had would have done that).

It looks like this bit:

    if off == 0xfe and ct1 == ct2:
      if ct1 == 0xfd:
        ext_device_name = 'Classic'
      elif ct1 == 0xfe:
        ext_device_name = 'Nunchuk'
      else:
        log( LOG_ERR, "Unknown device type %x" % ct1 )
    else:
      log( LOG_ERR, "Invalid memory read during controller attachment" )

Will need to be updated to handle the Guitar, but without one to play with myself I can't figure out what values to put in there.

Actually, looking at that the log should contain a line saying "Unknown device type xxxx" we need to add stuff to handle the guitar like:

    if off == 0xfe and ct1 == ct2:
      if ct1 == 0xfd:
        ext_device_name = 'Classic'
      elif ct1 == 0xfe:
        ext_device_name = 'Nunchuk'
      elif ct1 == xxxx:
        ext_device_name = 'Guitar'
      else:
        log( LOG_ERR, "Unknown device type %x" % ct1 )
    else:
      log( LOG_ERR, "Invalid memory read during controller attachment" )

Where 'xxxx' is whatever is in the log file, and 'Guitar' will have to be added to valid_ext_devices' or whatever it was. Of course we still won't actually have code to handle the Guitar.

[markmark]

Actually, as an idea for a quick and dirty fix, change it to:

    if off == 0xfe and ct1 == ct2:
      if ct1 == 0xfd:
        ext_device_name = 'Classic'
      elif ct1 == 0xfe:
        ext_device_name = 'Nunchuk'
      else:
        ext_device_name = 'Nunchuk'
        log( LOG_ERR, "Unknown device type %x" % ct1 )
    else:
      log( LOG_ERR, "Invalid memory read during controller attachment" )

Which will make it think the Guitar is a Nunchuck. Might be enough to get the buttons and stuff working, which would be all you'd need for FoF?

Thanks for all the awesome replies, I'll give it a shot later on tonight and report back on with a full writeup of what i had to do to get it working.
(if i can manage to tear myself away from frets on fire that is )
