Hi! I'm new in Mobileread forum. Few weeks ago I buy a Likebook Mars from amazon. I had Kobo mini, Kobo h20, but this ereader is at top

!
I've a question.

How I can use an off-line dictionary with stock reader?
I found some dictionaries on line, I download them and they work fine with Moon Reader Pro, but I'd like to use stock reader.
My dictionaries are babylon (.bgl) dictionaries. Do I need to convert them?
