Steam

Currently only for 32bit OpenELEC :(

=Settings=

Big Picture Mode
Steam has a display mode called Big Picture mode that is great for viewing steam on a HTPC where the couch is ~10' away.

Selecting this will always launch Steam in Big Picture mode until unselected.

You can always enter Big Picture mode from the normal Steam desktop.

Reset Steam
This option will blow out your Steam directory (it will save downloaded games and game data) and reinstall Steam.

No Guarantees here, use with caution.

=Audio= You will need an asound.conf so Steam can use ALSA. This may require some SSH knowledge to find the required card and device number. Config_sound_menusound

This is what I use

=Screenshots= A folder will be created in the userdata/addon_data SMB share upon first launch. /storage/.xbmc/userdata/addon_data/multimedia.steam/Screenshots

In Steam you can go into Steam -> Settings -> In-Game, then select "SELECT EXTERNAL SCREENSHOT FOLDER" and point it to the screenshots folder that was created.

=Backups= A folder will be created in the userdata/addon_data SMB share upon first launch. /storage/.xbmc/userdata/addon_data/multimedia.steam/Backups

This folder is linked to the internal Steam Backups folder so you can easily move backed up games or restore games by moving them to the Backups folder via SMB share.

=Games=

This list is incomplete (obviously) but I will continue to update it.
