# BRD
BRD is a tool for working with [*Dance Dance Revolution*][ddr] related data.
For currently supported features, see the [Modes](#modes) section.
## Installation
Currently this is not published as a crate so you either have to clone the
repository manually and run `cargo build --release` or you can use `cargo
install --git https://github.com/sbruder/brd` to install the binary without
cloning.
## Modes
### ddr2osu
This converts DDR step charts (.ssq files) and the corresponding audio (from
.xwb files) to osu beatmaps (in an .osz container).
Basic usage:
```shell
brd ddr2osu -s file.ssq -x file.xwb -o file.osz --title "Song Title" --artist "Song Artist"
# use musicdb from DDR A
brd ddr2osu -s file.ssq -x file.xwb -o file.osz -m startup.arc
```
To learn more about supported options run `brd ddr2osu --help`
#### Known Problems
* Since *osu!mania* does not support shock arrows, it either ignores them or
(by default) replaces them with a two-key combination (↑↓ or ←→); you can
change this with the (`--shock-action` option)
* Known problems listed for unxwb (for wave banks without entry names having
2 entries, which often are preview and full song, the longest one is used by
default).
### ddr2osu-batch
This batch converts songs from a musicdb (and therefore currently only supports
DDR A).
Basic usage (the `ssq` directory includes step charts and the `xwb` directory
includes wave banks):
brd ddr2osu-batch -m startup.arc -o out -s ssq -x xwb --source "Dance Dance Revolution A"
Batch conversion for older versions is possible with the included shell script
`batch_convert.sh` (usage guide at the top of the script).
### unxwb
This can list and extract sounds from XWB wave banks.
Basic Usage:
brd unxwb file.xwb
brd unxwb -l file.xwb
#### Known Problems
* It only supports sounds in [ADPCM][ADPCM] format. If you want to extract
sounds that are stored in other formats, you can use [Luigi Auriemmas
unxwb][unxwb] (<kbd>Ctrl</kbd>+<kbd>F</kbd> unxwb).
* For wave banks without name entries it does not yet offer the option to read
the names from [XSB files][multimedia.cx-XSB] and currently generates the
names from the index in the file (starting from 0).
### unarc
This can list and extract files from DDR A ARC archives. It extracts the
contents into the current directory.
Basic Usage:
brd unarc file.arc
brd unarc -l file.arc
### musicdb
This lists all entries from `musicdb.xml` or `startup.arc` files (only DDR A is
supported).
## About this project
This is my first rust project. Dont expect too much from the code in terms of
quality, robustness or idiomacity (especially regarding error handling). There
currently are no tests for the actual functionality.
Large portions of this tool would not have been possible without the following
resources:
* [SaxxonPike][SaxxonPike]s [scharfrichter][scharfrichter] which implements
[SSQ][scharfrichter-ssq] and XWB ([1][scharfrichter-xwb1],
[2][scharfrichter-xwb2]) and their [documentation about SSQ][ssq-doc]
* The [official osu! file format documentation][osu-doc]
* [MonoGame][MonoGame]s [XWB implementation][MonoGame-xwb]
* [Luigi Auriemma][aluigi]s [unxwb][unxwb] (especially the ADPCM header part)
* [mon][mon]s [ddr\_arc\_extract][ddr_arc_extract]
