As for launching apps, try using XBMC.RunScript which is what I switched to as XBMC.System.Exec was causing problems (don't recall the details right now).
Check your es_systems.cfg and verify that the command to run Dolphin is correct, I might have forgotten to change it back after switching to Dolphin standalone again.
If you simply read the first post, which you already should have done, the instructions on how to get the logs are provided there.
I wasn't sure which logfile was relevant, so i just attatched the .zip containing them all
I began by turning on logging in settings=system-logging
Then I launched ES and tried to play several games from various systems, no games would launch no matter the system selected
Then I launched Chrome successfully from my home shortcut
Then I launched Spotify and tried to play some songs
this is the entry in es-systems.cfg:
<system>
<name>wii</name>
<fullname>Nintendo Wii</fullname>
<path>/storage/roms/unraid/wii</path>
<extension>.gcm .iso .wbfs .ciso .gcz .elf .dol .dff</extension>
<command>/usr/bin/dolphin.start -e %ROM%</command>
<platform>wii</platform>
</system>
please verify the appropiate command using "XBMC.RunScript*what goes here?*" for ES, Spotify, Chrome, RetroArch
I'm not sure if it should be pointing to a .sh, a .py, or a "-start"/".start" command
anything else I can provide to troubleshoot this, please let me know, and thanks again. Just an additional note... the behavior was the same with ES and Spotify on fresh install of LE as well as after installing my personal build. (just eliminating that as a factor)
