I managed to get penelope working on my computer and semi-successfully converted the stardict Oxford Advanced Learner's dictionary into kobo zip format. However the dictionary has references to .wav files (see attached pic), presumably for pronunciation, but completely useless on my kobo and it makes the dictionary entry cluttered. Is there some way to remove these, either by editing the initial stardict file or the kobo zip file..?
Zip file attached if anyone wants it
EDIT: I realised I might be breaking some copyright rules by attaching the converted kobo dictionary
so I have removed it just in case!
