Versatile C++ game scraper: Skyscraper

movisman

Hi,

Can someone elaborate on the --skipped option for me?

I have read the help, however i'm building a command to use for future scrapes, and i'm not sure of the real difference / usage between --skipped and --unattend, except I know when using --skipped you get prompts, but it asks you anyway if you want to skip existing entries. So i'm not sure why you would use it?

Using --unattend removes the prompts and skips any existing entries when writing the gamelist, so again no need for --skipped, right?

I noticed when using the GUI via RetroPie -Setup, it uses --unattendskip and --skipped, but i'm still not sure why both are required.

In my case, I would use --unattend rather than --unattendskip because i'm renaming some of my files back to .chd after scraping them, and using --unattendskip wipes them off the gamelist if they've been renamed post-scrape.

Can anyone give me a heads up on the --skipped option and it's use case on it's own, as well as alongside --unattend and --unattendskip?

Just want to work out if it is an option I need to use or not. It seems like it's not necessary as the other options cover it, or the scraper asks you anyway when you don't run unattended.

Cheers

@movisman For any confusion with these, please check the output of the "--help" option. This shows you all of the options and what they mean.

EDIT: Btw, if you are building a command line to use in general, remember that you can set most options permanently in the ~/.skyscraper/config.ini file. That way you won't have to add then to the command line all the time.

Hi,

Thanks for the help. I have read all the options on the command line, I always try to check stuff out myself first - but am still slightly confused by the usage of the --skipped option and when it's required? I must be missing something obvious, but I am not sure why it would be used when you run either interactively or with the --unattend option.

Are you able to elaborate a bit for me? Apologies if I am missing something here.

Understood about the config.ini file, I think once I have a command working the way i'd like, i'll transition those into a .ini file for ease of use.

Thanks

@movisman I think --unattend also adds --skipped, I just left it in the scriptmodule to be set anyways. The --unattendskip was removed in the last version of the scriptmodules.

movisman

@mitu

Cheers. I need to use --unattendskip so it doesn't overwrite my renamed files, so I can leave --skipped off then I guess?

Does --skipped have any use on it's own? Considering interactive asks whether you wish to skip anyway - and --unattend also adds it? Does it have any use when combined with --unattendskip? From what I can tell, it appears not?

Thanks!

movisman

Sorry, corrected my command above as it was wrong!
Cheers

@movisman You seem to misunderstanding what --skipped does. The skipping prompt is not related to --skipped.

Answering yes to skipping at the beginning will skip all entries you already have in your gamelist, and therefore not try to rescrape them (and also not recreate the media for them). I never personally answer Y here as it makes more sense to let them be rescraped and regenerated from the cache. Answering Y will save you some time, but that's all. Basically it only makes sense to answer Y if you have manually changed some of the publishers, developers or data for some games in the gamelist.

Adding --skipped will make sure games that returned "not found" are still added as empty entries to the gamelist when it's generated at the end of a scraping run. That's all this option does.

I never personally use the --skipped option, but some people like to have those entries in the gamelist.

This is exactly what I was looking for. That's what it does! Thank you! Maybe the help could be slightly tweaked to mention the behaviour in slightly more detail, it might just be me though!

I actually don't want that for my use case, so I can safely not use that option. I also have to answer Y to skip existing entries for certain systems (or use --unattendskip) rather than have them be rescraped. The reason for this, is after scraping successfully, I have to rename the files back to a .chd extension for some systems (and edit gamelist.xml to suit), and answering N means they get rescraped and not found due to unique checksums etc, thus overwriting their entry in the gamelist with nothing.

Unless you have any ideas on a better way for me to manage this, I think I am ok to just use --unattendskip, because if I add the odd game later, I can use this command along with a query (if needed) to append new entries to the gamelist, and it won't overwrite my CHD entries mentioned previously.

Some systems which use .zip, are of course a lot easier. Does that make sense?

Thanks a lot for your help as always, this scraper is really very flexible and powerful.

movisman

Me again :)

I see there is Amiga support, but should it work with CD32 games (this is a separate section on screenscraper)? Running a basic command doesn't seem to yield any results, however, when I run a query against a valid SHA1 checksum, it finds and scrapes the information to the DB.

However when running the command again but with -s localdb, it doesn't write anything at all to the gamelist.xml or copy the media across. I am not skipping any files or anything like that.

Using the same command with other system (Atari 2600) is fine.

Before I spend more time troubleshooting, are you able to confirm if the system is even supported?

Thanks!

muldjord

@movisman Yes, the system is supported, but the Amiga platform is a bit difficult to work with as it is basically more systems inside one system. So Skyscraper looks for the "aga", "cd32" and "cdtv" in the filenames to switch the platform when scraping them. Please try scraping them using the openretro source. It will only work with games that have 2 or less words in them due to a limitation on their website, but openretro is the best source for amiga games.
If it scrapes the data when using a custom sha1 and the data is entered into the local cache, it will use the data when scraping with '-s localdb' afterwards. If it doesn't something is wrong with your command or your config.ini.

Hi there,

Thanks for the info. I stayed up late last night to try and get my systems scraped from the command line, and generally I had very good success.

Using a platform specific variant of the same command line for each system, I managed to scrape all of the obvious ones that have common .zip filenames with no issue at all. Others systems were a bit more picky, especially with me using .chd on all supported emulators, but I was able to sort with manual lookups and some file renaming to fool the scraper into obtaining the correct data.

A few of them incorrectly picked the wrong region for the game, for example Contra Hard Corps (USA) on Megadrive was picked up as Probotector, which is the European name. I haven't played around with the region forcing flags yet though. This is the next thing for me to tackle/address. Luckily there are only a few which have completely different names.

The only platform I had major issues with was the Amiga.

I was happy to do a manual lookup for every game (or any which do not pick up automatically). As there are about 20 in total so it won't take forever, and once it's done it's done. The plan was to do a manual lookup on a valid SHA1 and have it write to the localdb. I did a couple of tests and got a match on screenscraper. I was then going to scrape the localdb so it could write the changes to the gamelist.xml, but for Amiga only, this was just not happening. Using the same command (but changing platform and directory to suit) on another system, it was writing just fine. So I have no idea what is going on, i'll find the commands I used and paste them here.

Thanks for the heads up about having 'cd32' in the filename, some of the titles do not have this. I will also look into trying openretro.

@muldjord

Hi,

I think I solved the problem with Amiga. My CD32 files run from *.cue files (which is the most common for this system I think), and I had a suspicion that maybe the scraper wasn't supporting them.

So I added *.cue to an Amiga specific config.ini, and then scraped again from the local db.

It pulled the file straight in!

As a request, can you add *.cue support to Amiga possibly? Those who run CD32 will pretty much only use .cue files to launch I reckon.

Cheers!

@muldjord

One other question from me, do you think you might ever incorporate a function into the scraper where it is able to 'detect' the region?

I used a beta version of "Skraper" on my previous installation, which uses screenscraper.fr only, and this has a tick option in the GUI called "Use ROM region first (when available)", and then it has a free text priority list underneath, where you can put US, EU, etc - which I guess it uses if it cannot work out the ROM region itself.

When this option is ticked, any US roms I have get US artwork and naming, and EU ones get EU artwork and naming, etc, etc. It happens automatically, and seems generally very accurate.

I don't know how it works it out, maybe it uses information from the existing filename or something, not sure. But either way, is this something you could potentially incorporate as an additional switch, rather than having a fixed priority list?

I could use Skraper again, but I like the compositor and artwork style on yours better and prefer scraping from the command line as Skraper doesn't really work on Linux yet. And the fact I can use an SHA1 value as a one time override is excellent.

Cheers!

@movisman Skyscraper already has a switch to choose the region --region and even the language (--lang) for the sources that supports it.

movisman

@mitu

Hi there,
No worries, but that wasn't really what I was referring to - I know about the switch to set a region and have used it to set to US first, but Skraper has an option to set the region by rom somehow - before using a priority. It means my mixture of EU and US games get picked up correctly on a single scrape, whereas with skyscraper you have to explicitly set a region for the scrape or leave as the default priority (EU first). So it is an all or nothing approach, which doesn't work so well if you have say, a megadrive folder with both EU and US ROMs.

Does that make sense?

I understood your request in the first place, I didn't know if you were aware of the command line switches to choose region/language.

muldjord

@movisman I don't currently plan to change the existing region and language functionality. Currently it has a prioritized list it tries. If you set one manually it will move that region og language to the top of that list.

I have added .cue to the list of default supported files for Amiga.

movisman

@mitu

No worries, I thought there was some confusion, but thanks for the heads up, and as always, thanks for helping.

movisman

@muldjord

Perfect, thanks for adding .cue to the list of files.

No worries about the region functionality, if that won't change in the foreseeable future, I could always pop the EU games in another directory, scrape as US, move the EU games back, then scrape again as EU but use the switch to skip the previously scraped files. That should work...

I wonder how Skraper does it, perhaps it looks at the filename and makes a judgement. I have no idea but it does work quite well.

Cheers for all of the help so far.

muldjord

@movisman Can you give me examples of your filenames? I've decided to implement the region override (after a bit of thinking I realized this was a pretty easy thing to implement). But I need filename examples of how they are designated. For instance, are they called "Gamename (Europe).zip"? or maybe "Gamename (eu).zip"?

EDIT: The implementation is done now. I've implemented it so it looks for "europe", "usa", "japan", and "world" in the filename, but only if it comes after the first "(" and the user hasn't manually set the "--region" flag. It will then add that region to the top of the priority list automatically.

EDIT2: @movisman Skyscraper 2.8.2 now tested and released, please update and test out the region detection. You should get the artwork from the region that's in the filename if they are from the above mentioned regions.
