Retropie freezes

BuZz

At the end of the USB power cable - it's the part that plugs into the wall socket.

@lkmaster When you say it freezes, do you have to pull the power to restart, or is there just a very long (several minutes) delay when exiting EmulationStation?

I've found that if you have a huge collection of ROMS and scrape all the metadata it has a serious impact on the time it takes to exit EmulationStation/shutdown.

It does eventually exit though.

You can speed it up by switching off the parse gameslist on exit option but I think you may also lose any game metadata (last time played, total hours played) etc?

There's a backup script from @Drakaen391 that you could try:
https://github.com/Drakaen391/rpibu

Another option if you just want to backup saves is you could run this from the command prompt:

find /home/pi/RetroPie/roms/ -name "*.srm" -o -name "*.state*" | tar --transform 's|/home/pi/||g' -PcJf retropie_game_saves.tar.xz -T -

Restore with:
tar -C /home/pi -xJf retropie_game_saves.tar.xz

I actually got the above script here on the forums but I can't remember who posted it.
After you run this you can just move retropie_game_saves.tar.xz over to your USB flash drive

Try another Power supply / USB power cable
Try another SDCard with a new image

You can either press F4 on an attached USB keyboard to your Raspberry Pi (aka RPi) or SSH in using something like PuTTY. Once you get logged in, just type in (or copy & paste) exactly from my previous post (the first line in red).

find /home/pi/RetroPie/roms/ -name "*.srm" -o -name "*.state*" | tar --transform 's|/home/pi/||g' -PcJf retropie_game_saves.tar.xz -T -

Next make sure you have your USB flash drive plugged in to your RPi and then type cp retropie_game_saves.tar.xz /media/usb0
Another way to do the same thing is from your Windows PC use FileZilla to get retropie_game_saves.tar.xz from the /home/pi/ directory.

After you have re-installed RetroPie on your microSD card and you back up and running, then with that same USB flash drive in either push F4 and type cd /media/usb0 then tar -C /home/pi -xJf retropie_game_saves.tar.xz
or push it back over using FileZilla then press F4 and just type tar -C /home/pi -xJf retropie_game_saves.tar.xz

Hopefully that wasn't too confusing!

use the instructions above / or just copy your roms folder off over the network - also see https://github.com/retropie/retropie-setup/wiki/updating-retropie#making-a-backup-option-1

did you restore your save states by extracting the retropie_game_saves.tar.xz file after reinstalling RetroPie?
tar -C /home/pi -xJf retropie_game_saves.tar.xz

@backstander yes but maybe my savestates are in another direktory do you know how I can check this or change this?

You can search for files by using something like this sudo find / -name "<filename>” Most of the save state files end is ".state" so I think you could do something like sudo find / -name ".state". I don't use the find function that much.

I personally like to use Locate instead!
To install Locate type:
sudo apt-get install locate

To update the database that Locate uses to find files and directories:
sudo updatedb

Now all you have to do is type this to find something:
locate <filename>

Example: to look for those ".state" files you would do this:
locate .state

The only downside to Locate is that you sometimes have to update the database (sudo updatedb) to make sure you get all the newest files in your search. Updating will also remove newly deleted files.
