@adnifty said in Can't load save file - "Loading Task Failed" when hitting select+left Bumper:

On save state corruption/empty, how would I check that? This isn't happening with other games, so I bet this is the case.

The save state file is a .state file in the same folder as the ROM (file name is the same as your ROM file). You can either overwrite it by doing another save or just remove the file.

@that_fish_ said in Retropie not going to home screen:

@hostolis I got an error message

-bash: emulationstation: command not found

How did you install RetroPie? What hardware is it on?

everything was working fine earlier today,

I suppose the $64,000 question is, what did you do since earlier today?

What service does it say failed to start, up where it says "failed to start..."?

@thorr69 Yep, they're all in there. :-/

This doesn't look like a typical RetroPie installation - what version of RetroPie do you have installed ?
You may have ran out of disc space on the sdcard, you can check that by exiting EmulationStation and looking at the welcome message.
