Tygre I don't like to have to open Hippoplayer before opening AmiModRadio.
So what I've done is to rename your program to "AmiMod", delete its icon and make an icon-script launcher with this:
Run >NIL: SYS:Utilities/HippoPlayer/Hip HIDE QUIT
WBRun >NIL: SYS:Utilities/AmiModRadio/AmiMod
It works pretty well in my case. Of course if you can include the first command line in your program, all of this won't be necessary.
Edit: I've just read your wiki page
. I like what you want: "Having AmiModRadio use multiple players depending on the type of the modules: e.g., AmigaAmp for MP3s and HippoPlayer for modules"
But till that option is released, and like it is working right now playing just modules, I think Hip is the best option, so I prefer to open it automatically.
