Versatile C++ game scraper: Skyscraper

@Silent Just remove it afterwards. Or you can use the 'cacheCovers="false"' and so on options. I'll add those to the scraping modules section in config.ini aswell. That will provide what you are looking for.

EDIT: There, this will now be in 3.0.2.

Does anyone have any idea why I can't scrape two ROMs specifically? I'm using screenscraper and I can see in their database both the game and exact file I have (filename, crc, md5, and sha1 are exact matches)? This only happens on two specific ROMs that also happen to have period/. chars in their names (not sure if this is relevant). ROMs are in binary form - not zipped - as per the screenscraper.fr DB entry.

Running Skyscraper 3.0.1 via the RetroPie Setup script.

@fartsparkles Maybe it would help to give the names/crcs for those ROMs and what system they're in. They might exist on SS, but have a different system.

I tested with Skraper and had no issue scraping the ROMs. There are the specific ROMs that won't scrape with Skyscraper:
https://www.screenscraper.fr/rominfos.php?romid=315352
https://www.screenscraper.fr/rominfos.php?romid=314736
I'm not a C++ person so I haven't stepped through the code however I find it interesting that both these ROMs have periods in the name.

@fartsparkles I've been looking into this a bit, and I can rule out that it has to do with the "." in the file name (at least not on the Skyscraper side of things). I tested this by simply giving Screenscraper a custom query with the --query option where I specifically ask for the md5 or sha1 checksums of the rom you mention. And even by doing so, I still get a direct "Rom not found" back from Screenscraper. So this almost has to be a Screescraper bug, and not a Skyscraper bug. If Screenscraper does not provide a result when using a direct md5 or sha1 checksum query, I simply can't do anything about it.

EDIT: If you want to mess around with this yourself, here's the command line needed to try with specific md5 sums. You can also change that to sha1 if you want:

Skyscraper -p atari2600 -s screenscraper --verbosity 3 --query "md5=<CHECKSUM>" "<FILENAME>"

Verbosity 3 simply gives you a bit more details in the output.

EDIT2: Something is seriously wrong with Screenscraper right now. I can't get it to find any rom based entirely on checksum right now. I just tried with Super Mario World for Snes, and that only returns a reply on file name, not when I try just with the checksums. This usually works just fine.

My best advice is to give it a week and see if it resolves itself. I'm guessing they are having some issues with their database that needs resolving before this will work.

@muldjord Maybe I suffer from the same issue as @fartsparkles ? The strange thing is that Steven Selph's scraper, using Screenscraper, finds these 40 games that Skyscraper can't identify. I'll re-post what I just wrote on Reddit:

"I've been setting up a new RetroPie setup and thought I'd use Skyscraper. However, I'm having a strange issue with it. I have a curated list of NES roms which are all verified against No-Intro. Both RetroArch's own DB (which checks against No-Intro hashes) and Steven Selph's scraper (using Screenscraper) correctly identify these ROMs. However, Skyscraper fails on 40 of them, with "No returned matches".

Here's an example: Batman (U) [!].nes (MD5: 2e9f52556273aa735d0e75649541d812)

This ROM can be found at screenscraper.fr with the exact same hash: https://www.screenscraper.fr/rominfos.php?romid=135447

I've tried both versions 2.9.5 and 3.0.1 of Skyscraper. Same issue. Anyone have any ideas? Maybe /u/muldjord

I feel like I must be missing something obvious here... Still, the other methods mentioned above work out of the box with these ROMs."

I'm currently following some threads on their forums that might be related to this. For the time being Skyscraper seems to be blocked - no idea why. I'm awaiting reply from them.

EDIT: Skyscraper is currently banned from using the Screenscraper database due to the 4 passes I do with varying checksums and file name. I'm working on resolving this. It will most likely mean that Skyscraper will get a new API key and all users will have to update to a new version of Skyscraper when the new key has been issued. Stay tuned.

Ahh, okay! Do you think this ties into the issue I was seeing regarding not finding ROMs by using checksums?

muldjord

@Brunnis Sortof. :) I can't test anything right now as Skyscraper is blocked, so we'll see when the situation clears up.

@muldjord I was about to ask why I get « no game found » for all my roms using screenscraper.

Thanks for the heads up. Keep us posted (and keep up the good work!)

Regards :)

muldjord

The good people of Screenscraper has been very helpful in figuring out how to move forward with this and the issue is now resolved. Stay tuned for more info soon...

mo418

@muldjord I confirm. Working like a charm now

Thanks for your support :)

Edit: Lots of games not found though, but it’s the 2nd time I use your scraper so I don’t know if it’s a setting issue or else.

muldjord

@mo418 This will probably be better once the new release (3.0.2) is out. There are issues with the screenscraper module currently in addition to the previous key ban.

Skyscraper 3.0.2 released: https://github.com/muldjord/skyscraper

Upped the rom limit from 5 to 35 for the "igdb" module
Upped the rom limit from 25 to 35 for the "mobygames" module
Added media cache config options to module section
Add Sharp X1 platform as "x1"
Now exits nicely when running low on disk space
Added 'spaceCheck=<BOOL>' to config.ini
Fixed crash when using '--startat' and '--endat' where the '--endat' file name came before the '--startat' file name. Note! What 'ls' reports in alphabetical order is not always what Skyscraper see as it it locale specific. So be aware of this. A huge thanks to 'Gemba' for taking the time to investigate this bug thoroughly.
Fixed bug in game list metadata preservation when using relativePaths and '<folder>' entries (thank you to 'HumanRob' for reporting this)
Fixed game list entries skipping for 'relativePaths' and '<folder>' instances
Skyscraper now saves the cache and exits nicely on ctrl+c (SIGINT) (thanks to 'krcroft' for pointing this out)
The 'screenscraper' module now includes 'systemeid' in the query for better results
Now skips the game list assembling when in gathering mode
Now skips cache saving when in game list generation mode
Output now says whether it was a gathering run or a game list generation run

Fixed a bunch of stuff in the game list skipping and metadata preservation code. This was sortof b0rked before when people used relative paths. Should work as expected now. Let me know if you find cases where it doesn't work.
The screenscraper module now includes 'systemeid' in the query which should give better results for all platforms.
I've also included another quite important feature which is the "exit nicely" when user presses ctrl+c to stop a scraping. Before it would simply force the process to die. Now it let's the currently running threads finish up the entries they are working on and then saves the cache for the stuff it has gone through. Before this data was lost. So this is a huge improvement.

Brunnis

@muldjord That’s awesome! I can’t test it out until tomorrow morning. Do you have reason to believe this also fixes the issue where Skyscraper missed hits on hashes that should have been found?

muldjord

@Brunnis Yes, I can do manual md5 searches now, so that should be fixed too.

mitu

Yes, just updated and tried an MD5 search (the one reported first with the Atari 2600 E.T game) and it's found now.

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

Currently you have the option to either scrape from scratch, or to only scrape entries that don't already exist.

I cannot find this option. I don't want to accidentally scrape all 2000+ games, I only need to scrape about 50 which are new.

I'm using Skyscraper 3.0.1 on retropie from the Retropie tools menu.

mo418

When it says [...] PASS 1 ——— Game [gametitle] not found :( ———

Does it mean it will make other passes until it will find the rom media in screenscraper?

Updated to 3.0.2 and I still get a lot of them (while UXS found them all, except very few titles) so there must be something going on.

Also, is there a way to export the games titles that were not found?

Thanks in advance!
