I've been having issues with SyntaxHighlighter with my new Blogger theme, so I'm using this post to get the bugs worked out.

I was having issues with posting XML code, but I think I've resolved them.
Here's an example of my XML problems. The image below and the code above it should be the same:
For a period of time, the XML code snippets looked like this:
The two StackOverflow questions that have been helpful in researching this topic are here:
This tutorial shows how to get one to four wiimotes (the controller of Nintendo Wii) running with RetroPie with or without a classic controller (attached to the wiimote).
Note: Put the dongle in one of the USB ports of the Raspberry Pi directly, don’t put it into a USB hub (I read somewhere that it doesn’t work even with an active USB hub).
The "uinput" device needs to work with non-root users. To do so, create a file called /etc/udev/rules.d/wiimote.rules with the following line: KERNEL==“uinput“, MODE:=“0666“
Reboot the Raspberry Pi to make this change active.
. Check that the blue-tooth dongle works: Command /etc/init.d/bluetooth status
should return that bluetooth is working
. Scan for the wiimotes. Start hcitool scan
and press 1+2 on your wiimote(s). After a short while, the output should be something like
Scanning ... 00:19:1D:87:90:38Nintendo RVL-CNT-01 00:19:1D:88:EF:12Nintendo RVL-CNT-01
Take a note of the addresses of your wiimotes (the 00:19:1D:87:90:38 in the output above), we need that later.
Note: If the scan is not successful try it again. Sometimes you need to try it several times (I read that somewhere, but it always worked for me the first time).
Correct usage of wminput
For every wiimote, we need one wminput command to map the wiimote (and the classic controller) buttons to something emulationstation and the emulators can work with. wminput comes with configuration files (in directory /etc/cwiid/wminput). I created my own configuration file, which works if you use a wiimote with or without a classic controller. Create the file /home/pi/mywminput with the following content:
Classic.Dpad.X = ABS_X Classic.Dpad.Y = ABS_Y Classic.LStick.X = ABS_HAT0X Classic.LStick.Y = ABS_HAT0Y Classic.RStick.X = ABS_HAT1X Classic.RStick.Y = ABS_HAT1Y Classic.A = BTN_A Classic.B = BTN_B Classic.X = BTN_X Classic.Y = BTN_Y Classic.Minus = BTN_SELECT Classic.Plus = BTN_START Classic.Home = BTN_MODE Classic.L = BTN_TL Classic.R = BTN_TR Classic.ZL = BTN_TL2 Classic.ZR = BTN_TR2 Wiimote.A= BTN_A Wiimote.B= BTN_B Wiimote.Dpad.X= -ABS_Y Wiimote.Dpad.Y= ABS_X Wiimote.Minus= BTN_SELECT Wiimote.Plus= BTN_START Wiimote.Home= BTN_MODE Wiimote.1= BTN_X Wiimote.2= BTN_Y
If the Raspberry Pi is started and emulationstation starts, we want to register the wiimotes so they can be used with emulationstation and the emulators.
I did it the following way: mkdir /home/pi/bin
create file /home/pi/bin/attachwii.sh with the following content:
#!/bin/bash hcitool dev | grep hci >/dev/null if test $? -eq 0 ; then wminput -d -c /home/pi/mywminput 00:19:1D:92:90:38 & wminput -d -c /home/pi/mywminput 00:19:1D:84:EF:33 & else echo "Blue-tooth adapter not present!" fi
Note: You need one wminput line for every wiimote you want to use (i.e. the above is for two wiimotes)
Note 2: You need to replace the addresses of the wiimotes above by the addresses of your wiimotes (shown by command "hcitool scan" as shown above).
make the script executable with chmod 775 /home/pi/bin/attachwii.sh
have the script be started just before emulationstation starts. To do so, edit the file /etc/profile
The last line should be [ -n "${SSH_CONNECTION}" ] || emulationstation
right before this line, add the line /home/pi/bin/attachwii.sh
and save the file.
If you now do a reboot, wait until emulationstation has been started. When it did, press 1+2 on all of your wiimotes to register the wiimotes. Now you can "tell" emulationstation and the emulators to use the wiimotes (and the classic controllers). Here are my configuration files.
For emulationstation:
Content of /home/pi/.emulationstation/es_input.cfg for two wiimotes:
For retroarch:
End of file /home/pi/RetroPi/configs/all/retroarch.cfg (for two wiimotes):
input_player1_joypad_index = "0" input_player1_b_btn = "0" input_player1_y_btn = "2" input_player1_select_btn = "8" input_player1_start_btn = "9" input_player1_up_axis = "+1" input_player1_down_axis = "-1" input_player1_left_axis = "-0" input_player1_right_axis = "+0" input_player1_a_btn = "1" input_player1_x_btn = "3" input_player1_l_btn = "4" input_player1_r_btn = "5" input_player1_l2_btn = "6" input_player1_r2_btn = "7" input_player1_l3_btn = "10" input_player1_r3_btn = "10" input_player1_l_x_plus_axis = "+2" input_player1_l_x_minus_axis = "-2" input_player1_l_y_plus_axis = "-3" input_player1_l_y_minus_axis = "+3" input_player1_r_x_plus_axis = "+4" input_player1_r_x_minus_axis = "-4" input_player1_r_y_plus_axis = "-5" input_player1_r_y_minus_axis = "+5" input_player2_joypad_index = "1" input_player2_b_btn = "1" input_player2_y_btn = "3" input_player2_select_btn = "8" input_player2_start_btn = "9" input_player2_up_axis = "+1" input_player2_down_axis = "-1" input_player2_left_axis = "-0" input_player2_right_axis = "+0" input_player2_a_btn = "0" input_player2_x_btn = "2" input_player2_l_btn = "4" input_player2_r_btn = "5" input_player2_l2_btn = "6" input_player2_r2_btn = "7" input_player2_l3_btn = "10" input_player2_r3_btn = "10" input_player2_l_x_plus_axis = "+2" input_player2_l_x_minus_axis = "-2" input_player2_l_y_plus_axis = "-3" input_player2_l_y_minus_axis = "+3" input_player2_r_x_plus_axis = "+4" input_player2_r_x_minus_axis = "-4" input_player2_r_y_plus_axis = "-5" input_player2_r_y_minus_axis = "+5"
Make sure that the settings are only one time in retroarch.cfg file (i.e. if you have a line input_player1_b_btn = "0"
in the retroarch.cfg file before adding my lines, remove (or out-comment) the whole section. If you want to use more than two wiimotes, search for the line input_player1_joypad_index = 0
in retroarch.cfg and add the a corresponding line for the other wiimotes. For example you should have the following lines in retroarch.cfg for four wiimotes:
input_player1_joypad_index = 0 input_player2_joypad_index = 1 input_player3_joypad_index = 2 input_player4_joypad_index = 3
Finally, add the following two lines at the end of /home/pi/RetroPi/configs/all/retroarch.cfg:
input_enable_hotkey_btn = "0" input_exit_emulator_btn = "1"
This will exit the emulator when you press A+B simultaneously on the wiimote (or the classic controller).
Note: the config files above work for wiimotes with or without classic controller.
Note 2: If you want to use the wiimote (i.e. not only the classic controller) and you are using my config files, you need to hold the wiimote horizontally (with the power button on the right).
