Versatile C++ game scraper: Skyscraper

quicksilver

When scraping a game that won't be able to be found by it's checksum, Screenscraper will attempt to match by exact rom name from what I understand. However if there is more than one game with that exact title it will fail to scrape. I have a number of .sh and .conf files that cannot be found by checksum but fail based on ROM name because there are many versions of the game in screenscraper's database (quake II for example). Is there anyway to work around this?

Not that I know of. This is a small limitation in how their database handles things. I do believe it only searches on the platform in question though, so this shouldn't happen too often as the platform id is also send in the requests.

@Silent Awesome, I'll look into it and include it in the next release. Thanks.

EDIT:

Only igdb has a platform for Steam related platform called steamos. I have added that to pc and steam but it is only relevant when scraping with igdb
steamplatform added with all relevant aliases including steamos
ps2 platform added with all relevant aliases
*.ml added for all platforms

I'll leave out ps3 and x360 for now. I don't want to spam platforms all over the place just for the sake of it.

@muldjord strangely the built in scraper in emulation station will find the same titles using screenscraper as the source, unless of course it searches for ROM name differently. Either way, I was able to scrape those problematic games using different sources. Again, thank you for your help. I have been promoting skyscraper every chance I get!

Can you give me an exact file name and platform for a game it doesn't find that the built-in scraper does find when using screenscraper as source? I would like to test this.

@muldjord "Oregon Trail II". It's a .conf file in my PC folder. Built in scraper will find it with screenscraper as the source but skyscraper will not. There were a couple others, but Im away from my pi and can't remember off the top of my head. But I'll check when next I'm home.

Edit: "Myst" is another one.

pc and ports have the exact same aliases

I wondering if the built in scraper doesn't have multiple aliases for PC and that's why it's able to find them.

Nope - the internal scraper (when using ScreenScraper) only knows about pc, for ports it ignores the platform and queries by name only.

EDIT: either that or the Ports system is considered as pc by Emulationstation.

@mitu thanks for the confirmation. I would assume that's where the difference is then.

Oh, that's right. It uses the new search query instead of the jeuInfos, right? Then that's the difference. I might look into using the search query one at one point.

No, it's still using the game info endpoint (v2 WebApi). I've looked over using the search endpoint - see my post on their forum about the search returning to many unrelated results. However, the search is slower then the game info endpoint and I think it's not worth (at the moment) the effort to switch to it - considering their server(s) are already busy. Improving the search over the regular game info endpoint is a better investment at this point (checksum, search-by-name, search-by-id).

Skyscraper 3.1.2 released: https://github.com/muldjord/skyscraper

Added support for Moonlight '*.ml' extension for all platforms
Added 'ps2' platform for use with Moonlight and all other supported Ps2 extensions
Added 'steam' platform for use with Moonlight '*.ml' files
Fixed minor bug in CRC checksum calculator for 'screenscraper'
Improved workarounds for ScreenScraper XML errors

Yet again I fixed some errors in the screenscraper module. My CRC checksum calculator sometimes returned 7 char strings. This caused issues with the replies from screenscraper, so I've made sure I check the length and prepend a "0" when this happens. I also improved some of the workaround for the XML errors screenscraper sometimes send out.
Lastly you should now be able to scrape moonlight files with all platforms as requested by @Silent. Pretty untested though, so let me know how this works for you.

@muldjord I quickly tested scraping a few "roms" from screenscraper/thegamesdb/igdb and I can confirm it seems to work fine :) Thanks a lot!

EDIT:
Quick observation: I tried to scrape this game off MobyGames:
https://www.mobygames.com/game/spintires-mudrunner

MobyGames name is "Spintires: MudRunner", whereas my .ml file is named "Spintires MudRunner". If you try to search for it like this on the website, you get normal results:
https://www.mobygames.com/search/quick?q=Spintires+Mudrunner

Yet, Skyscraper couldn't find it unless I leveraged aliasMap.csv to add : to the name. API's fault or Skyscraper not filtering results well enough?

Silent

Another note: I can't find absolutely nothing for steam platform from thegamesdb scraper. My cache has entries for those, which means I used to be able to find things smoothly, but now I can't.

EDIT:
Also, looks like NVidia Gamestream added support for Forza Horizon 4:
https://www.mobygames.com/game/forza-horizon-4

Platform there shows as "Windows Apps", and looks like Skyscraper can't find it because of that either.

Double negative, but I assume you meant "I can't find anything". I have added the *.ml extension to be id'et by filename since they are scripts. This might have fixed it but you will have to scrape all of your ml files all over again. I just re-released 3.1.2 for this. Maybe I should start doing betas instead.

I've also added the "windows apps" alias to steam and pc. So please re-update to 3.1.2.

EDIT: Figured out why you get no results with thegamesdb. They've apparently added new platforms and I haven't updated my internal list in a while since I mostly focus on retro platforms. So I'll need to figure that out... Let me look into this.

Seems like this is due to their API. The query Skyscraper sends for that file name is "spintires+mudrunner". This gives a result when using the website search, but not when using the API.

Ok, thegamesdb should provide more results for the steamplatform now. But I had to add aliases for the xbone and ps4 for it. It rarely returns PC results it seems, which is really odd. But not something I can change. Re-released 3.1.2 again... Please re-update.

I love this tool, thanks for making it. Really does wonders for scraping roms.

Would appreciate a tiny bit of help. I've read the documentation and various threads but yet to find an answer. So far doing really well with Skyscraper. It's amazing! But I'm having an issue with one or two games that share a name with each other and it's driving me crazy!

Particularly, there's a MAME title called Badlands. Then there's a MAME title called Bad Lands. It's always selecting the default incorrect one for my needs and I don't know how to get it to offer me a choice between them. I thought the --interactive option would help but it didn't seem to make any difference. How can I select the correct one? For info I am using Skyscraper on my PC running Manjaro Linux. It's otherwise perfect.

Any help with this very much appreciated. :-)
