Take and Scrape Your Own Screenshots
Taking your own screenshots and creating your own gamelists
Sometimes the boxarts and other sources for scraping can be low quality and inconsistent in sizes, whereas in game screenshots are standardised to the same size. The following is a simple guide with a script that will help automate the process of taking and scraping your own screenshots.
A few disclaimers first:
MAKE A BACKUP AND USE AT YOUR OWN RISK!
You have to be comfortable with basic Linux commands and simple file editing.
You need to have an updated version of RetroPie-Setup scripts (version 4+) (updating instructions here).
You can only create one screenshot per game
This only works with RetroArch emulators
If using the methods described here, the Runcommand's Launch Menu Art option won't show the scraped screenshot image.
Take a Screenshot
Before talk about the "scraping your own screenshots" trick, we need to know how to take screenshots in RetroArch. If you already know how to do it, you can go to the next section.
Access the RGUI (usually with Select+X) and go to
Quick Menu ->
The default screenshot button is
F8 which means if you've configured your keyboard through emulationstation you have to hold the hotkey button (by default the button you configured as select) and then press F8. If you want to have it so that you can take a screenshot with your controller you'll change the screenshot button to a button that isn't already being used for hotkey behaviour. To do this you'll edit the overall or global
The key line you want to change is ~line 580
# Take screenshot # input_screenshot = f8
So in my case I changed it to my right analogue thumb on my xbox controller (number values vary with diff controllers)
# Take screenshot input_screenshot_btn = "12"
So in game when I want to take a screenshot I hold select (or rather the back button on the xbox controller) and press the right analogue thumb.
The runcommand menu is what is run every time you play a game, It is what allows you to change emulators, set video resolutions, among other things. One lesser known function is the ability to add customised scripts to be executed on the start and/or on the end of the game.
runcommand-onstart.sh script is executed (if exists) before the game starts, and
runcommand-onend.sh is executed (if exists) after you exit the emulator. Both files must be at
The two methods described here take advantage from these features.
Here we have two methods to scrape your own screenshots:
Method 1: uses the
runcommand-onstart.sh to automatically set some screenshot related configs in system specifics
retroarch.cfg files. And after you take some screenshots from the games, you use the SSelph scraper to create a
gamelist.xml with them.
Method 2: uses the
runcommand-onend.sh to automatically set the most recent screenshot from a game to be the emulationstation image for the respective game.
The main difference between them is:
Method 1: automates the
retroarch.cfgconfigs but you have to use SSelph scraper tool from command line every time you want to update the
gamelist.xmlwith your screenshots.
Method 2: you have to manually edit
retroarch.cfgconfigs, but automates the placement of your screenshots as the respective emulationstation game images.
Now you have to choose which one you want to follow (or read about both):
- "I didn't like how it looks! I want my old images back and disable this stuff!"
You need to create a file called
runcommand-onstart.sh in the folder
copy the following contents:
#!/usr/bin/env bash system="$1" imgdir="$HOME/RetroPie/roms/$system/images" configdir="/opt/retropie/configs" mainretroarch="$configdir/all/retroarch.cfg" systemretroarch="$configdir/$system/retroarch.cfg" source "/opt/retropie/lib/inifuncs.sh" iniConfig " = " '"' # Create images folder in each respective rom folder mkdir -p "$imgdir" # If there is no auto screenshot setting in the main retroarch.cfg add it if ! grep -q "auto_screenshot_filename" "$mainretroarch"; then iniSet "auto_screenshot_filename" "false" "$mainretroarch" fi # If there is no system based screenshot directory defined then define it in the system based retroarch.cfg if ! grep -q "screenshot_directory" "$systemretroarch"; then iniSet "screenshot_directory" "$imgdir" "$systemretroarch" fi
Now you can play your games and take your screenshots and it will fill your images folder with your screenshots.
Create gamelist with Sselphs scraper
If you haven't already, download sselphs scraper from the setup script
Now that you've got your screenshots ready all you have to do is use sselph's scraper to generate a gamelist for your screenshots- this will effectually link your roms to their respective screenshots.
You need to exit emulationstation first
so again using the snes as an example
cd /home/pi/RetroPie/roms/snes /opt/retropie/supplementary/scraper/scraper -img_format=png -add_not_found=true -download_images=false -image_suffix=
For more information on the options for sselphs scraper see here
it will create a gamelist.xml file in
/home/pi/RetroPie/roms/snes which takes precedence over the gamelist.xml in
and if all went according to plan, when you boot emulationstation back up your images will be the screenshots that you took! TADA!
Also if you want to only add images and leave metadata out entirely you can tell it not to scrape from any databases with
Behind the Code
The following is all taken care of by the aformentioned script but if you're interested this explains essentially what the code is doing (and how you can set it up manually without a script)
You need to add the following line to
auto_screenshot_filename = "false"
This will tell retroarch to name any screenshots taken after the rom name you are playing
System Specific retroarch.cfg
You need create an
images folder in each rom folder you want screenshots for and then set the system based retroarch.cfg screenshot path to each respective
images folder so that the images can be easily joined with sselphs scraper, unlike the default retropie behaviour this will keep your images and gamelists in each system folder with your roms; the pattern is as follows:
so for example if I'm adding screenshots to the snes I would create:
Then I would add that screenshot path to:
# Settings made here will only override settings in the global retroarch.cfg if placed above the #include line input_remapping_directory = "/opt/retropie/configs/snes/" screenshot_directory = "/home/pi/RetroPie/roms/snes/images/" #include "/opt/retropie/configs/all/retroarch.cfg"
then we would take our screenshots and use sselphs scraper to generate our gamelist.xml's as above.
What exactly this method do
If you take a screenshot during a gaming session, the most recent screenshot will be the emulationstation image for this game. This task is done by a
Obviously, there are some conditions to make it happen, in order to let the user easily turn on/off this functionality.
Limitation: This method doesn't work if the emulationstation "save metadata on exit" option is turned on, because it makes emulationstation overwrite the changes made by the
runcommand-onend.sh. Turn it off in the emulationstation Main Menu -> Other Settings -> Save Metadata On Exit.
There are two conditions related to RetroArch configuration in order to make it works:
auto_screenshot_filename = "false"
screenshot_directory = "/some/path/to/screenshots"
auto_screenshot_filename = "false" means that your screenshots will NOT be named automatically, they will always be named as
ROM file name.png. Therefore your most recent screenshot will always overwrite the previous one.
Remember this to avoid confusion:
auto_screenshot_filename = false means ON for this "scrape screenshots" method. If
auto_screenshot_filename is true (or absent), it means OFF.
The directory assigned to
screenshot_directory MUST exist, otherwise RetroArch won't be able to save the screenshots.
Those options can be set in global or system specific
global config (easy way)
/opt/retropie/configs/all/retroarch.cfg and put the option
auto_screenshot_filename = "false". This option isn't present in the default
retroarch.cfg, so put it in the beggining of the file is good idea (easy to edit it later).
And then put another line to the option
screenshot_directory = "/path/to/screenshots" (I use
/home/pi/screenshots, but you can set any other valid path). Remember: the directory MUST exist, otherwise RetroArch won't be able to save the screenshots.
system specific config
If you are happy with the global config, you can jump to the next section. If you want system specific customizations, go on with the reading.
/opt/retropie/configs/SYSTEM_NAME/retroarch.cfg (replace SYSTEM_NAME with the obvious) and configure it like in the global config above.
The system specific configs take precedence over the global ones. So if you want to explicitly turn on/off this functionality for a specific system, you can set
true, respectively. Note that you have to explicitly set it to
true to turn off the scrape screenshots for a specific system. If it is absent, the script will look for this config in the global
If you want to use system specific folders for screenshots, set the
screenshot_directory option in the system specific
retroarch.cfg. If it is absent, the script will look for this config in the global file.
Here we will add a script to be executed when the game ends. If you took a screenshot in a gaming session, the script will automatically set the most recent screenshot as the emulationstation image for the game you've just played.
Get the script that makes it happen here: https://raw.githubusercontent.com/meleu/share/master/screeper.sh
From the command line:
wget https://raw.githubusercontent.com/meleu/share/master/screeper.sh mv screeper.sh /opt/retropie/configs/all/runcommand-onend.sh
(If you are a shell script guy, maybe you like to read the code. It's well commented.)
Now you can play your game and take your screenshots. The most recent screenshot will be put in your screenshots folder and will be the emulationstation image for this game.
You have to restart emulationstation in order to see the changes. If all went according to plan, your screenshots will be the game images!
"I didn't like how it looks! I want my old images back and disable this stuff!"
Easy, only two steps:
- Change the
auto_screenshot_filenameto true in
runcommand-onend.shwill do nothing if this option is true).
- Delete the system specific
gamelist.xmlthat is at the system roms directory (example for SNES:
~/RetroPie/roms/snes/gamelist.xml). It makes the emulationstation get the configs from the original
gamelist.xml(more details on how gamelists works here).
Restart emulationstation and done!, you have your old scrapes back!
