Batch downloading games from Newgrounds

[Corrupt-Specturion]

Since gallery-dl doesn't seem to have the ability to batch download Newgrounds users' games (individual game links work, but downloading the whole user page doesn't download the games, and gallery-dl https://(user).newgrounds.com/games returns [ytdl][warning] [generic] Falling back on generic information extractor [ytdl][error] ERROR: Unsupported URL: https://(user).newgrounds.com/games [ytdl][error] Failed to extract video data), is there a way I can? Alternatively, is this feature planned?
I apologize if this doesn't quite belong in the issues category.

use link gopher extension as an alternative

It needs to be hands-off automated like the rest of gallery-dl, so this doesn't quite cut it. Thanks for the suggestion though. (I do now realize that I should have specified in the post.) While we're specifying things, it needs to be Linux Mint Mate 20.2 compatible, and preferably a CLI program.

individual game links work

It might appear that way, but it really doesn't. It downloads a "zip" file, which is actually just the main HTML page of a game without any of its code or resource files.

Making it work properly is also not easily possible with how gallery-dl works internally, given it uses customizable filenames for every file it downloads.

This is also the reason why /games listings are not supported.
You got an ytdl error since you have the ytdl extractor enabled, I presume, which gets all URLs unsupported by gallery-dl.

By "game", I meant Flash games, sorry if that was unclear. I already know about the HTML5 game issues.

Would there be a way to only have it download Flash games from the games section?

[afterdelight]

you mean the .swf files?

[Corrupt-Specturion]

Yes

Downloading everything from /games got implemented in 0393e59.

I didn't realize there are still .swf games available on Newgrounds and thought that all had been converted to HTML5, but there are even ones from 2022: https://www.newgrounds.com/portal/view/829032

Would there be a way to only have it download Flash games from the games section?

--filter "extension == 'swf'" should do that.

[Corrupt-Specturion]

Thanks. One last question, though: does --filter "extension == 'swf'" only apply to the games section, given gallery-dl https://[user].newgrounds.com?

[mikf]

No, --filter applies globally / to everything.

You can use the image-filter option (wrong name, I know) to set a filter for only the games subcategory, either with -o extractor.newgrounds.games.image-filter="extension == 'swf'" on command-line or by setting this option inside "games" inside "newgrounds" in your config file.

edit: Another method would be checking whether the file in question is of type game first (ff532d6):
--filter "type != 'game' or extension == 'swf'"
