RetroArch for Wii and Wii U with Retrode 2 and XBOX360 controller support

Retrode 2

• The Retrode 2 cartridge reader offers USB mass storage access for your SNES and Genesis/MegaDrive cartridges. This works out of the box on the Wii!
• With my driver you can also use your SNES and Genesis/MegaDrive gamepads on your Wii!
• Support for 4 players!
• Tested with various games: Super Mario World, Street Fighter 2, Super Bomberman, Sonic and Boulder Dash
• I also maintain the Snes9x GX Retrode fork.

XBOX360 controller

• Only XBOX360 wired version is supported (VID=0x045e, PID=0x028e)
• One XBOX360 controller works fine, in theory multiple controller should work, too, but is not tested.
• The LED shows which device slot is selected: 1-4. On some controllers the LED always flashes.

HOWTO

• Connect your Retrode 2 and the XBOX360 controller, then start RetroArch.
• USB drives are not tested! RetroArch prefers SD cards!

Configuration Hints

• My releases are already configured, so you need to do this only with a fresh RetroArch build.
• Add the autoconfig file Retrode.cfg to SD:/apps/retroarch-wii/autoconfig
• Create directory SD:/retroarch/config
• Configure input joypad driver to hid, then restart.
• I usually add these values to the default config file retroarch.cfg. (Or use the RetroArch menu to configure.)

    input_joypad_driver = "hid" # Wii only!
    all_users_control_menu = "true"
    # open RetroArch menu with start+select (4) 
    input_menu_toggle_gamepad_combo = "4"
    joypad_autoconfig_dir = "sd:/retroarch/autoconfig/hid"

Notes

• If you want to use an additional USB gamepad, please note: RetroArch Wii/Wii U only supports certain USB gamepads: VIDs/PIDs are hardcoded and an autoconfig file has to exist. As described in the official commit message.
• I also noticed that the autoconfig files for the Wii have a slightly different button layout. Just reconfigure if you have copied a file from another platform.
• Original SNES Mouse is not supported. (I don't have one, but if you give me the RetrodeTest output I could add it...)
