Test a new data source for sselph/scraper

sselph

@DrMaxwell Nice to see you again.

@lilbud https://github.com/sselph/scraper/issues/102 The issue was that I assumed data sources would handle both metadata and images so having a source just for images was something that requires more work.

@Pyjamarama With my limited knowledge of MAME and arcade I called the flag -mame but it goes for all arcade systems like fba, neogeo, etc.

DrMaxwell

@sselph I assume you have documented any and all new options in the help section of the program:

scraper --help

How can people access 3D versus 2D versions of art from the screenzone database?
I've noticed if all three databases are set to true, the metadata is more complete; is there an order or hierarchical preference that the scraper pulls this metadata from?

Thanks for the further development of this tool. Your scraper is the fastest in the business!

sselph

Yes -help should have it. -console_img="b" is the default which is 2D boxart -console_img="3b"would get the 3D boxart. Right now the order is gdb, ss, ovgdb but I need to rework some of this to handle specifying the order.

DrMaxwell

@sselph I think having a preference would be good. Silly question, but does the scraper check against all three sequentially; for example, if the first doesn't provide the metadata, then it goes to the next database until both image and metadata are found?

sselph

@DrMaxwell Thats the idea but it might stop without getting an image and only metadata. I can't remember.

@sselph I like this mix template for scraping. How could you do this? Could you integrate into your script option? Thanks a lot!

tien_huu_1408

@sselph Any update for the script?

@sselph it is amazing how fast SS as a source is!!!

I notice two things while using it though...

I can't scrape any arcade games (mame, fba, neogeo)
With one specific gba rom I get always the following error message and the scraper stops:

Can you enable scraping games that are on an external drive.

DrMaxwell

@lilbud Just put the scraper executable in the same folder as your roms; whether or not the drive is external is irrelevant.

sselph

@paradadf Thanks. I found the issue and have it fixed on github. I wasn't passing the error returned when the bad image was found and caused it to crash when using -missing. I can't reproduce the image error. Maybe that game was fixed? or it was temporary. I also only set this up to scrape console games. I didn't do arcade since it uses names instead of hashes and hadn't done any testing on that.

paradadf

@sselph the rom works perfectly, so I don't understand what's the problem.
Anyway, I just noticed that the letters with accents á, é, ó, etc... aren't being shown on the xml file (those letters are just erased).

Hi @sselph, happy to hear you're working on the scraper again, I've used it every time I've worked with RetroPie. Not sure if you had seen recent development news of RetroPie, but they are working on emulators for PSP (ppsspp), Nintendo DS (desmune) and GameCube (dolphin). So, I was wondering, will you be adding support for scraping PSP/NDS/GameCube games? Or is there a way to scrape for those systems that I'm just not aware of?

PSP:

NDS:

Gamecube would be possible, I think, as the hashes are listed on redump

Nightfire

@robertybob ahh, ok, thanks for the info, guess I never went to the 'issues' when I was there.

spannernick1

Will this scraper have UK box art as well,the ones that come with ES are not good at finding Mega Drive and CD Pal box art,had to end up adding them manually ,sometimes it adds a completely different game when its not that game.

robertybob

@spannernick1 Don't bother with the ES scraper, use Sselph's one.

Sselph's scraper should match (Europe) roms to Mega Drive games and (USA) roms to Genesis games. If not, first check whether the image uploaded to thegamesdb.net is actually for the correct region (more often that not it isn't). http://thegamesdb.net/browse/36/ If the Mega Drive game is listed there and the artwork is for the Europe copy, then check which region your roms are.

Failing that, segaretro.org has all the best quality Mega Drive scans :)

paradadf

If you use the flag -region with eu in the first place, it will find the megadrive box art, assuming it exists and, of course, it is pressent on www.screenscraper.fr
SS either has added to his database the media from the best possible sources, or the people has contributed creating it.

paradadf

I'm not really sure how retropie handles scummvm. I saw on the wiki that you use either .sh or .svm extensions (?). Anyway... this information is valid for recalbox, I suppose that you use files as shortname.svm (or .sh). If you put the fullname inside those files as shown here, you will be able to scrape scummvm using SS as well. I'm assuming that both extensions are already known by the scraper. @sselph Would you mind adding .scummvm to the list, please?

tien_huu_1408

@sselph : I have downloaded scraper code (rpi2 version). On Raspberry Pi 3.
How to use it by terminal?
Hope you could help me step by step, especially for scraping 3D image.
Thanks a lot. Hope to hear from you asap.
