Hi folks,

this is no request, I just wanted to post my little conversion script here. I found several Wii games that use sdf as audio format, which is currently unsupported. The following script converts these files to something playable.
This could also be a template for a generic script.
Have fun!

Code:

# converts Wii SDF audio files to playable GENH streams

set REVERSE 1
