libretro-thumbnails

Thumbnails for RetroArch, split into individual repositories to ease maintenance.

Install

Check out the repository, with all submodules, into RetroArch's thumbnails directory:

cd ~/.config/retroarch
git clone --recursive --depth=1 http://github.com/libretro-thumbnails/libretro-thumbnails.git thumbnails

Update

To bring in the latest thumbnails across all systems, use:

git pull --recurse-submodules
git submodule update --remote --recursive

Or by using the script which will maintain shallow clones (depth=1) and checkout master:

sh update_modules.sh

Usage

• Thumbnails are installed into RetroArch config's thumbnails directory
• There are three types of thumbnails:
  • Named_Snaps are in game snapshots
  • Named_Titles are title screen snapshots
  • Named_Boxarts are the boxes or covers for games
• Thumbnails follow the following naming convention:

  thumbnails/Playlist Name/Named Type/Game Name.png
  

• The following characters in playlist titles must be replaced with _ in the corresponding thumbnail filename:

  &*/:`<>?\|"
  

• Images must be .png format
• Image resolution guidelines:
  • Images with native width larger than 512px should be scaled down to 512px wide
  • Images with native width of 512px or less should be added as-is
• Substitute promotional material is acceptable when no official boxart is available
• Use libretro-thumbnails-check to check for missing thumbnails

Testing

To check for files with invalid file names, use the following command....

find . -name '*[&\*:`<>?\\|"*]*'

The libretro-thumbnail server provides two functions...

.index Files
