Versatile C++ game scraper: Skyscraper

  • Skyscraper 3.1.5 coming up in a few days. I had some leftover changes that are actually pretty cool, some minor additions as requested by users and some platform additions. And I've also added a --cache report:missing=<RESOURCE> option.

    I don't have much time for Skyscraper these days, so I want this stuff out there. I just need to do some testing over the coming days to make sure everything is still a-okay.

  • @muldjord Thanks for adding those two I submitted the ticket about. :)

    You're welcome :)

  • Skyscraper 3.2.0 released:

    • Improved output of edit mode to show queue size and initial prioritized resources
    • Now clearly shows missing resources when adding resources in editing mode
    • Made '--cache vacuum' more verbose at verbosity level 2 or higher
    • Removed platform check for screenscraper module as it wasn't really necessary
    • Added 'videoSizeLimit' config variable (Thank you to 'silverfr0st' for suggesting this)
    • Now also processes brackets for skipped games (Thanks to 'hexive' for pointing this out)
    • Added 'arcadia' and 'astrocde' MESS platforms (Thank you to 'raphkoster' for suggesting these)
    • Added '--cache report:missing=<GROUP or RESOURCE1,2,...>' option (Thank you to JaymesRS for suggesting this)
    • Added '--fromfile' option allowing you to work on a subset of files taken from a file. Compatible with files created using the '--cache report' option
    • MobyGames module now includes 'platform' id query when relevant. Should improve result accuracy
    • Added region support for MobyGames cover artwork
    • Added A LOT of regions to region autodetection in general
    • Now no longer creates media folders when in resource gathering mode
    • Moved help texts for '--cache' options to '--cache help'

    Lots of interesting stuff in this release. The --cache edit function has been improved a bit to better show what resources are missing on each rom. I've also added a nifty --fromfile <FILENAME> option which allows you to add filenames, one per line, into a file and use it with this option. Skyscraper will then work on those files only. This brings me to the new --cache report:missing option which allows you to create file reports containing filenames of all files missing certain resources. When those are created you can then combine the edit option with the fromfile option and add the missing resources like so --cache edit --fromfile /home/pi/.skyscraper/reports/reportfile.txt.

    I've also improved region autodetection quite a bit. It will now detect pretty much all relevant regions and / or countries from the rom filename. Also added region support to mobygames covers!

    As for minor stuff, some new platforms were added and some requested features aswell. Check the list above for all of it.

    Let me know if you run into problems.

    Have fun!

    @muldjord Thank you!

    I'm excited to now be able to scrape my PC Engine CD roms, as I was getting a "Platform not set" error before.

    Keep up the good work!

  • @A-Bored-Ninja This has not been addressed in this release. Otherwise it would have been part of the release notes, sorry. Or have you found some other way of doing it?

  • @muldjord I assumed that when you took the platform option out of screenscraper it would sort of resolve itself for me.

    Since I have a screenscraper account and get six threads that's always what I use.

    What I not benefit from the screenscraper platform removal?

  • @A-Bored-Ninja Ah, yes, that is correct. I thought you were talking about the "platform alias" option I have under consideration which is not yet implemented (and might not be as it a pretty big change for little gain).

  • Hi @muldjord, is it possible to "clean up" the media? Let's say I had a bunch of games that were scraped and looking good, but some time later they were deleted for being dupes, or I just didn't want them anymore. Is there an easy way to delete the media associated with those now deleted games without clearing all of the media folders and cache, and scraping everything again? And can the cache be emptied if the games already have their media in the media folders after generating the gsmelist? Because with the cache and media folders combined I believe there's a duplicate of every media file, correct? Thanks for the help.

  • @OldSchool Yes, but only from the cache. Please read the documentation for the --cache command here

    Particularly the --cache vacuum option.

    Concerning the ES media folder Skyscraper can't and won't keep track of what is in it. Remember that Skyscraper supports multiple frontends. Keeping track of all that is mindbogglingly difficult. But as long as you haven't made manual changes and kept your Skyscraper cache, you can just delete the media folder and regenerate the gamelist and media files. Then it will be "clean" again.

  • @muldjord Great! Appreciate the reply.

  • Found a bug in my mobygames cover download code that could result in an endless loop. 3.2.1 just released with this fixed, please update.

  • Skyscraper 3.2.2 released:

    • Added 'bat' scripts to sha1 special handling list (please purge platforms using 'bat' files and rescrape)
    • Now discards 'ZZZ(notgame)' results from ScreenScraper
    • Fixed double-quote issue when reading titles from scummvm.ini
    • Made location of scummvm.ini configurable in config.ini
    • Fixed bug in roman and integer numeral conversion functions
    • Rewrote the entire 'screenscraper' module to use JSON instead of XML

    Fixed some bugs and rewrote the ScreenScraper module from the ground up. I checked out their JSON response format and decided it was a lot cleaner to work with than the XML format. Obviously, with a total rewrite, there can be issues. I've tested it both with unregistered use and with registered use and haven't found any issues beyond what would have happened when using the XML format.

    Let me know if you run into problems.

    Have fun!

  • Skyscraper 3.2.3 released:

    • MAJOR: Added support for the 'Pegasus' frontend (set with '-f pegasus')
    • Now checks for, and removes, double bracket notes in final game list title
    • Fixed minor bug in the 3D gamebox effect renderer
    • Completely transparent images are no longer saved when compositing (Thank you to metallkopf for getting me to finally fix this)
    • Optimized the final game list assembling code to use game entry references instead of copies
    • Optimized all cache resource iterations to use const references instead of copies
    • Optimized the entire codebase by removing all Qt-centric foreach iterate-by-copy to use references instead
    • Fixed bug where 'screenscraper' would only look for ESRB age classification
    • Potential faulty JSON replies from Screenscraper are now saved to '~/.skyscraper/screenscraper_error.json' for easier debugging

    Most prominent new feature is the support for the Pegasus frontend. Use it with -f pegasus. Keep in mind that the default artwork.xml is not well suited for the default Pegasus theme, so I suggest using this:

    <?xml version="1.0" encoding="UTF-8"?>
      <output type="screenshot" width="640"/>
      <output type="cover" width="640" height="480">
        <layer resource="cover" height="480" align="center" valign="middle">
          <gamebox side="wheel" rotate="90"/>
      <output type="wheel" height="200"/>

    Which will give you this:

    Please also remember to disable the EmulationStation linking in the Pegasus UI settings. And equally important, when a platform has been scraped, remember to add the metadata.pegasus.txt to Pegasus afterwards. The games won't show up until you do.

    I've also done quite a bit of optimization resulting in a 10% speed boost when generating game lists. Oh, and completely empy and transparent images are no longer saved in the media folders.

    Have fun! And please report any problems you might run into. There's a lot of code rewrite going on at the moment, so some bugs could have snuck in.

  • A quick note to anyone reading this: There is currently a bug in the ScreenScraper API that causes some searches to return a faulty JSON document (the raw data format). I've reported this to ScreenScraper.

    EDIT: They should have fixed this now, so if you still encounter JSON errors, please create a bug report report at the Skyscraper github and attach the screenscraper_error.json file as the Skyscraper output instructs. Thanks! :)

  • @muldjord Yeah, I stumbled upon this yesterday. Thanks for the announcement.

  • @muldjord hey. thanks for the great work on skyscrapper.. just a qick question.. is there a way to try scrapping only missing games? (Skiping games already in DB and cache )?

  • @dudumaroja Just disable refresh, and it will load all existing games from the cache (which is quite fast). Other than that, you can also use the --startat and --endat command line options to narrow the scope of the scraping run. :) But the most common error people do is to enable refresh without knowing what it means. Enabling refresh means that it will always fetch the data from the online source, even though it has already been cached.

  • @muldjord Excuse me for jumping in on that, but I just started using Skyscraper. Will it complete missing resources from already cached games? If, say, a game has everything cached but a Video, will SS download the Video on the next run (without refresh) if it becomes available?

    I'm asking because AFAIK, Sselph's scraper which I used up until now doesn't do that for games that are already in the gamelist. It doesn't use a cache like SS does, though.

  • @Clyde No, if a game has previously provided a result for any resource, it won't fill in the holes unless you run a refresh on it. This is how the databases work. If you look up a game on any of the databases, it will give you most, if not all, of the info in one request. At that point it only makes sense to use all of it or not look up the game again at all.

    The idea is to use the --cache edit or the import module feature to fill in the holes. You can use the --cache report:missing=<RESOURCE> to figure out what your games are missing. And you can use the --cache edit --fromfile <REPORT FILE> afterwards to edit only the games missing any of the resources in the reports.
