Downloads cases from Ace Attorney Online to be playable offline.
- Backup cases in a way that makes them fully playable offline by downloading all referenced assets.
- Use parallel downloads to download case data quickly.
- Download multiple cases at once.
- Use the
-1flag to compile the case into a single HTML file, without the need for a separate assets folder. - Choose a specific version of the Ace Attorney Online player (e.g., if a case only works with an older version).
Releases are provided for download, but you can also simply build the tool yourself (see below).
Cases can be downloaded by just putting the trial ID as an argument to aaoffline:
aaoffline YOUR_ID_HEREOr, even simpler, you can pass the URL1 to the case directly:
aaoffline "http://www.aaonline.fr/player.php?trial_id=YOUR_ID_HERE"You can also pass more than one case at a time (separated by spaces) if you want to download multiple cases at once.
By default, the case will be put into a directory with the case title as its name. You can change this by just passing a different directory name as -o some_directory. If there are multiple cases, each case will be put into its own folder, again with the case title as its name, all under the directory chosen with -o (or the current directory if none was set).
The downloaded case can then be played by opening the index.html file in the output directory—all case assets are put in the assets directory, so if you want to move this downloaded case somewhere else, you'll need to move the assets along with it.
Alternatively, you can pass the -1 flag to aaoffline, which causes the case to be compiled into a single (large) HTML file, with the assets encoded as data URLs instead of being put into separate files. (Warning: Browsers may not like HTML files very much that are multiple dozens of megabytes large. Your mileage may vary.)
There are some additional parameters you can set, such as --concurrent-downloads to choose a different number of parallel downloads to use2, or --player-version to choose a specific commit of the player.
To get an overview of available options, just run aaoffline --help.
Building aaoffline should be straightforward:
cargo build --releaseAfterwards, you can find the built aaoffline executable inside target/release.
Alternatively, you can also install the tool to be globally available:
cargo install --path .Then you can run aaoffline from anywhere.
This is due to the HTML5 audio API being implemented differently in Firefox, refer to #1 for details.
As a workaround, use the --disable-html5-audio option with aaoffline, and then use a local HTTP server to serve the files—this way, the HTML5 audio API is not needed.
If you have Python installed, you can run python3 -m http.server -d CASE_DIRECTORY to run a simple web server, then you just need to access the URL it outputs.
