Versatile C++ game scraper: Skyscraper

muldjord

@hermit Skyscraper supports many of the MESS platforms simply by scraping them with their own names such as:

$ Skyscraper -p nes -s screenscraper

But GX4000 in particular isn't supported.

Hi! Skyscraper scraps many games for me, but some it does not scrap are quite common which I find odd. E.g. Chaos Engine and Lemmings.

@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. :)

annomatik

thanks, will do. Which checksum tool should I use (either Windows or Raspbian would be fine)?

@annomatik On Linux you can use md5sum <filename> or sha1sum <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!

@muldjord Thanks for the replay about the psx games. I was able to write a script that would read the m3u file to get the cue file, and then grab the checksum of the bin/cue files and grab the correct images using --query. It works great.

I have another question/issue. I just scraped my nes roms and Super Mario 2 seems to grab the japanese wheel no matter what I do. I've tried --region 'us', 'eu', and 'wor', but I always get the "Super Mario USA" wheel.

Is this an issue with the way I'm running Skyscraper? an issue with the program itself? or an issue with the screenscraper database? Can you repeat this?

The wheel I want is located here:
https://screenscraper.fr/image.php?gameid=1248&media=wheel&hd=1&region=wor&num=&version=&maxwidth=600&maxheight=300

Skyscraper -p nes --refresh --region 'wor' --unpack -s screenscraper -i . -o . -g . --pretend /mnt/exhd0/roms/nes/Favorites/Super\ Mario\ Bros.\ 2\ \(USA\)\ \(Rev\ A\).zip

The md5 of my (unzipped) rom is d769d73689ea4684dbb0bd7cf3a24b2f.

Thanks

@annomatik Skyscraper already matches just filenames when it looks for games at screenscraper. But it only works if the filename is unique in their database. So if they have 2 roms with the same filename, it won't work. This is not a Skyscraper thing, but a screenscraper thing, so not something I can change. You can try scraping the games with some of the other sources. They are filename search based.

You can, however, overwrite the checksums Skyscraper uses when looking for the games with the '--query' option. Read more about that here: https://github.com/muldjord/skyscraper/releases/tag/2.7.5

It works from 2.7.5 and newer. :)

@tacodog I'll need to look into that when I get the time. It could be a bug of some sort. If the '--region us' doesn't pull it in, there might be a problem. If the wheel exists in their database, it should use it. If it didn't it will prioritize other regions until it finds one that does exist. So either there's a problem with the us wheel in their database, or there's an issue in Skyscraper. Should be easy to reproduce though.

tacodog

@muldjord One more request/suggestion. Would it make sense to divide the import directory by system? My understanding is that all images now go in import/screenshots. So if I wanted to use custom images for Mortal Kombat 2, I would have to remember to change the images in the import directory when building snes or megadrive databases. Not really a big problem, just an idea.

annomatik

Cool, will try the query option. Thanks!

annomatik

Didn't work :-( I used the following script, it said it scraped something, but when I started Emulationstation again, there still was no meta-data for the games I specified:

#!/bin/bash
./Skyscraper -p nes -s screenscraper --query sha1=F5E4CD9F287A8233EEE35AD1881B2770D9F2C453 "/home/pi/RetroPie/roms/nes/Balloon Fight (USA) 2P.nes"

@annomatik You need to always rescrape with:

$ Skyscraper -p [platform]

when you've added new data to the cache as you just did. That will regenerate the gamelist.xml using all of your cached data. Please read the github documentation thoroughly. It's all very well-documented including these features. :)

muldjord

@tacodog That's a good idea, I will add it to the roadmap. :)

annomatik

Thanks, that worked. To be honest, I'm a little overwhelmed by the doc, so if it's ok for you, I'll just ask my question here.

Next topic. After scraping, I now have a "Adventure Island 3", a "Adventure Island Classic" and a "Adventure Island II".

What I'd like to have instead: "Adventure Island 1", "Adventure Island 2" and "Adventure Island 3".

Where would I specify that so it does not get overwritten with the next db update? Thanks

annomatik

Also, is it possible to configure the console-colors used? The yellow is very hard to read on a white background. Thanks!

@annomatik If you wish to use your own titles (and keep them) for any game, I suggest using the 'import' feature. Please read the documentation on how to use that. I am not gonna go over it here as it is already well-documented.

I will answer questions that aren't covered in the documentation, but I expect you to take your time and read it, overwhelming as it might be. Just read the sections you need to learn about. It'll be worth it in the end.

As for terminal colors, I don't know if you can change them in Putty. I am not a Windows user myself, so you will have to look into Putty's documentation. There is not a way to change them in Skyscraper.
