## Creating the disk image
After compiling, you need to generate a disk image with [mkpsxiso](https://github.com/Lameguy64/mkpsxiso):
```bash
mkpsxiso -y isoconfig.xml
```
## Using ffmpeg to generate a CDDA compliant Wav file
Needed Specification : `RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz`
### Conversion
```bash
ffmpeg -i input.mp3 -acodec pcm_s16le -ac 2 -ar 44100 output.wav
```
### Merging two mono audio channels into one stereo channel
```bash
ffmpeg -i herb.wav.new -filter_complex "[0:a][0:a]amerge=inputs=2[a]" -map "[a]" herbi.wav
```

<!-- MKPSXISO example XML script -->
<!-- <iso_project>
Starts an ISO image project to build. Multiple <iso_project> elements may be
specified within the same xml script which useful for multi-disc projects.
<iso_project> elements must contain at least one <track> element.
Attributes:
image_name - File name of the ISO image file to generate.
cue_sheet - Optional, file name of the cue sheet for the image file
(required if more than one track is specified).
-->
<iso_project image_name="hello_ovl_exec.bin" cue_sheet="hello_ovl_exec.cue">
<!-- <track>
Specifies a track to the ISO project. This example element creates a data
track for storing data files and CD-XA/STR streams.
Only one data track is allowed and data tracks must only be specified as the
first track in the ISO image and cannot be specified after an audio track.
Attributes:
type - Track type (either data or audio).
source - For audio tracks only, specifies the file name of a wav audio
file to use for the audio track.
-->
<track type="data">
<!-- <identifiers>
Optional, Specifies the identifier strings to use for the data track.
Attributes:
system - Optional, specifies the system identifier (PLAYSTATION if unspecified).
application - Optional, specifies the application identifier (PLAYSTATION if unspecified).
volume - Optional, specifies the volume identifier.
volume_set - Optional, specifies the volume set identifier.
publisher - Optional, specifies the publisher identifier.
data_preparer - Optional, specifies the data preparer identifier. If unspecified, MKPSXISO
will fill it with lengthy text telling that the image file was generated
using MKPSXISO.

Optional, specifies the license file to use, the format of the license file must be in
raw 2336 byte sector format, like the ones included with the PsyQ SDK in psyq\cdgen\LCNSFILE.
License data is not included within the MKPSXISO program to avoid possible legal problems
in the open source environment... Better be safe than sorry.
Attributes:
file - Specifies the license file to inject into the ISO image.

<directory_tree>
<!-- <file>
Specifies a file in the directory tree.
Attributes:
name - File name to use in the directory tree (can be used for renaming).
type - Optional, type of file (data for regular files and is the default, xa for
XA audio and str for MDEC video).
source - File name of the source file.
