Screenshots Project Service
Purpose Provide a repository of screen shots of supported games.
Maintainer(s) Eugene Sandulenko (Sev)


We try to have screenshots on our website for all games that we support. The purpose of this page is to describe how new screenshots are to be made to ensure uniform overall quality. In particular, what scaler you should use, how files should be named etc.

List of screenshots we need

How to make screenshots

Here are additional rules on how to make screenshots which were settled in the last couple of years: (Of course any suggestions are welcome!)

  • Check if this particular screenshot hasn't already been committed.
    • If there is no visual difference between an already submitted screenshot and your game version, don't submit it.
    • If you are submitting screenshots for non-English game, use only those which have visual difference (changed graphics) or have something written in that language.
  • ScummVM settings
    • Pick an interesting scene to take the screenshot of.
    • 320x200 games should be run with HQ2x (Ctrl+Alt+3) mode with aspect correction (Ctrl+Alt+a) mode on. I.e. it should be 640x480 image.
    • 640x480 games should be run with 1x scaler.
    • On platforms which use the SDL backend (Win32 and *nix included) Alt+S creates a screenshot file called scummvmXXXXX.bmp inside the current directory.
    • Make sure your screenshot is 640x480 and was made with HQ2x scaler (if originally 320x200). Otherwise it won't be accepted.
  • Screenshot file details.
    • Screenshots should not contain any window decorations.
    • The only supported file format is PNG with maximum compression.
    • Preferably run OptiPNG and advpng after that. Use default parameters for OptiPNG and -4 parameter for advpng for best results. If you don't, we'll have to do it later.
  • File name is gametarget[-platform][-lang]-X-full.png where:
      • gametarget is the game target name, see our compatibility page for the full list
      • platform is an optional parameter for cases when you submit non-PC game version screenshots
      • lang is an optional parameter when screenshot for non-English version
      • X is a sequental number.
    • Create a .txt file containing the file names followed by full game name and optionally provide the platform name and language in parenthesis. For example "Indiana Jones and the Fate of Atlantis (Amiga German)"
      • There is no need to provide titles for every file if they're all the same. Use your discretion.
  • If possible, use the script to produce thumbnail versions of your screenshots. If you don't have it or can't use it, then save in interlaced JPEG scaled down to 256 pixel width with quality 0.33 (or higher, watch for the compression artifacts). Optionally you can commit/submit only PNG and TXT and we will create the thumbnails for you.

How to submit screenshots

  • If you have write access to the web module in the SVN repository, you can commit it directly. NOTE: Don't forget to add the binary format key (-kb).
  • Alternatively, you can submit it via our patch tracker.
  • If you didn't perform some actions with the screenshot file, for example if you didn't compress it or were unable to produce thumbnails, please mark your submission accordingly.
