Desmume 2015 Mic Sample #605
Description
Describe the bug
The documentation lists the "sample" option for microphone input and states that this is where the user may specify a file sample to use for microphone input.
Expected behavior/changes
The documentation should explain how to set said sample file.
Additional context
As the only DS core on RetroArch with this feature, it would be nice to know how to do it.
