Versatile C++ game scraper: Skyscraper
-
@analoghero Hey man, I've implemented the checksum option you suggested some time back. It's currently on the master branch and will be in 2.7.5 to be released soon. :)
It works by using the command line option '--query' which basically takes either a search query for the filename based scraping modules, or either 'sha1=[checksum]', 'md5=[checksum]', or 'romnom=[filename]' (rom name in French). It also requires a single rom to be passed on command line like so:
$ Skyscraper -p [platform] -s screenscraper --refresh --query sha1=[checksum] /[path]/[to]/[romfile.zip]This will allow you to override the checksums used when searching for the game. So you can look one up at screenscraper, and just use that.
-
@muldjord Nice! Thanks for putting your time into this. Hipe that others could use this option, too.
-
@analoghero It's a niche feature for sure, but I got another request for it, and I figured out a way to implement it in a way I was satisfied with. :)
-
Skyscraper version 2.7.5 released: https://github.com/muldjord/skyscraper
- Fixed a bug where 'brackets="false"' in config.ini would be flipped (Thanks to Vynce for reporting this)
- Completely refactored pass procedures for cleaner code and to enable '--query' option
- Added '--query' command line option. This option requires a single rom file to be passed on command line aswell, otherwise it will be ignored (Thank you to AnalogHero and Vynce for suggesting this)
- Added scrapers to 'psx' and 'pc' platforms when using Simple Mode
To elaborate on the "--query" option, this is how it works: For most modules a search query is sent to the scraping module in an URL format. That means that a filename such as "Rick Dangerous.lha" becomes "rick+dangerous". The '+' here means a space. You could probably also use the URL encoded space "rick%20dangerous" but my tests show that most modules expect spaces as '+'. And it is the "rick+dangerous" that you, as the user, can pass as the query, like so:
$ Skyscraper -p [platform] -s [module] --query "rick+dangerous" [filename]Remember to also add a filename that you wish to use the override with. Otherwise the query will be ignored.
But, not all of the scraping modules are search name based. For instance, the "screenscraper" module can use a variety of different search methods. So for screenscraper, you also have the option of overriding the checksums it use to search for a game. This is especially convenient in cases where a filename exists multiple times in their database and your own local file doesn't match with any of the connected checksums (maybe you've compressed the rom yourself or whatever).
In this case you can look up one of the working checksums on "screenscrapers" website (screenscraper.fr) and override the checksum like these examples:$ Skyscraper -p [platform] -s [module] --query sha1=[checksum] [filename] $ Skyscraper -p [platform] -s [module] --query md5=[checksum] [filename] $ Skyscraper -p [platform] -s [module] --query sha1=[checksum]&md5=[checksum]&romnom=[exact url encoded filename] [filename]The last example combines two of the checksum options and even the "romnom" option which is "rom name" in French (this is a screenscraper thing, not a Skyscraper thing). You obviously only need one of the checksum options, it's just to show that you can combine them if you really need to.
The '--query' option is clearly an "experts only" option, but for those that like to go down the rabbit hole, I am your humble servant. Down you go... :D
And happy scraping! :)

@muldjord Dont know if im doing something wrong, but the new query option isnt working for me. I tried this
$ Skyscraper -p amiga -s screenscraper --query md5=0D5E4770B34021A666E9CADF0F39DA75 /home/pi/RetroPie/roms/amiga/BlackViper_v1.0_AGA.lhaand it outputs
1/1 (T1) Pass 1 ---- Game 'BlackViper_v1.0_AGA' not found :( ----What am i doing wrong?
EDIT: Ok. It works. Just used a different entry from screenscraper.fr md5=7858DFE8AE9A6725B6CAD18D67FEBA61 worked.
-
@analoghero Yeah, I ran into this problem with amiga games aswell. It needs to be the same platform, otherwise it won't match them even though you put in a custom checksum. So for instance, if you copy a sha1 from a cd32 game and try to override it for a standard amiga game, it won't be found. It will be found if you use the amiga version. So this should not be an issue as I assume people will always be using sha1's from the actual platform.
Btw, Skyscraper differentiates the Amiga platforms from the filenames. If a filename has 'cd32' or 'cdtv' in it, it will switch to that platform for that rom.
-
@muldjord Just checked for the Screenscraper DB ;) "Amiga CD32", "Amiga AGA", "Amiga CDTV",... are child of "Amiga" ;) so if you scrape a CD32 rom on "Amiga" system, it normally return the good game referenced on "Amiga CD32" ;)
It's the same for "MAME" for exemple, if you scrape a CPS1 game in the MAME System, it will return the good game (not needed to specify CPS1 ;) ).
-
@screech Yes, this is true, but switching the platform (in Skyscraper) is necessary for the match to occur. If you scrape the 'amiga' platform with Skyscraper, it will not accept an entry for the 'Amiga CD32' platform because some scraping modules are name search based. So it needs to change the platform in order to accept the returned entry. :)
With Screenscraper this is less important since it's checksum based. But for the others, it's a necessity since many games are multiplatform, and Skyscraper needs to find the right one. :)
-
I have a couple question about the usage of Skyscraper that I was hoping someone could help with.
My first issue is that I use m3u files for my psx games because it handles multi disc games organically giving me just one entry in emulationstation. My m3u file points to ../psx-discs/...(disc 1).bin ../psx-discs/...(disc 2).bin etc. If I scrape by m3u filename, nothing is found. If I check by disc, I get duplicates for each disk, and the gamelist file doesn't point to the m3u. Is there a way to search by filename rather than checksums?
Secondly, I have scraped all of my systems using screenscraper, and I am missing a handful of files.
Local database cache stats: 'screenscraper' module Titles : 428 Platforms : 428 Descriptions : 426 Publishers : 418 Developers : 412 Ages : 171 Tags : 414 Ratings : 279 ReleaseDates : 316 Covers : 428 Screenshots : 428 Wheels : 423 Marquees : 423 Videos : 0I'd like to fill in these small gaps (just 3 wheels) from a second source, but don't necessary need to grab everything all over again. Is there a way to tell Skyscraper to only get the missing files? Or can I see which files are missing so I can try to grab them manually?
Thanks

@tacodog You can scrape single files simply by providing the full or partial path to the rom on command line. You can also use the '--startat' and '--endat' command line options to only scrape a span of roms. As for seeing exactly which roms are missing the data, that is currently not possible.
For the m3u issue, the reason it isn't working for those is that the source you are using (ScreenScraper) doesn't have those exact files in their database. You'd need to overwrite the checksum manually, which can be done with '--query'. Try checking out the release notes for 2.7.5 here: https://github.com/muldjord/skyscraper/releases/tag/2.7.5
It's described in there. You can also try scraping it with another source, such as "mobygames" or "thegamesdb". They search by name instead of checksum, so if your filenames are good, they should provide good data. Not for wheels though, as those sources don't support wheels.

would it be possible to scrape Mess roms?
example for Amstrad GX4000 :
barb2.zip = Barbarian 2
brubber.zip = Burnin' Rubber -
@hermit Skyscraper supports many of the MESS platforms simply by scraping them with their own names such as:
$ Skyscraper -p nes -s screenscraperBut GX4000 in particular isn't supported.

@annomatik Most of the LHA's are not yet in the screenscraper database. It will work for some of them with the openretro module, but overall they are poorly supported at this time (for all scrapers, not just Skyscraper). We are in the process of making them work with both openretro and screenscraper.
As for the nes games, try looking them up on the screenscraper site and check if your checksums for your roms match those in their database. If they do please provide some documented examples of matches that don't return a result and I can look into this further. Thank you. :)
-
thanks, will do. Which checksum tool should I use (either Windows or Raspbian would be fine)?
-
@annomatik On Linux you can use
md5sum <filename>orsha1sum <filename>, on Windows I think you can use Powershell to compute them - https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/get-filehash?view=powershell-6. -

@annomatik said in Versatile C++ game scraper: Skyscraper:

I posted in your other topic how you can check the data on the Screenscraper.fr site, each game has it's own set of name/roms/hashes associated (in the 'ROMs/ISOs' tab of the game detail page)
-
Wow, that's a ton of games there... :-)
I just checked the first couple of games. Balloon Fight, Banana Prince, Castlevania 2, Donkey Kong Jr. : many versions are there, but not with the checksums I have.
So... I can think of at least four solutions:
- Do I really have to keep looking for the right roms ? That would be probably a lot of effort.
- I could try adding my own versions to the lists, but why, the meta-data is already there, the roms are working fine, there's already many different versions of the same game (why not just have a list of different checksums for the same game?)...
- Could Skyscrapper just match filenames, not CRC sums? How would I enable that? and, if not
- Can I maybe give Skyscrapper a pointer to the right meta-data?
In Kodi, it is possible to add a .nfo file, which can contain the link to the details-page of a movie / tv show episode. It is in the exact same solution like the video, just instead of mp4/mkv/whatever, it has the extension nfo. In its simplest form, it's just a simple link, but it can also be used for storing all meta-data, if wanted. And if combined with a link, it first takes the provided meta-data from the nfo and takes the rest via scrapping from the nfo.
Maybe, if that's not yet possible, it would be possible to provide direct links somehow?
Thanks!
