I'd like to load some custom dictionaries on my Kobo Glo, since the preloaded ones sometimes lack many words.

The monolingual ones seems to be fairly complete, but I find the ones used for translation to be far from comprehensive.

I know that there is a tool called Penelope, aimed at converting between various dictionary formats, but the job seems especially tricky for Kobo ones, since it requires many dependencies.

If someone has successfully used it to create Kobo-compatible dictionaries, can please point out if there is some place where they can be downloaded?

  • No, these are the direct links to the standard Kobo dictionaries, if one prefer to get them that way instead of directly downloading them on the device via wi-fi.

Apologies for replying as an answer, I have no sufficient reputation to comment.

I am the creator of Penelope. I thought about this for a bit, but the main problem is that I am continuously asked to "convert" materials that are clearly pirated from copyrighted, commercial dictionaries --- which I always refuse --- and hosting them onto a public web site would yield to legal issues.

Probably the best option would be creating a thread in MobileRead, but clearly only for public domain or CC-licensed materials.

EDIT: I created such thread: http://www.mobileread.com/forums/showthread.php?p=2755188

EDIT 2: I posted directions on how to install custom dictionaries on Kobo devices in the Penelope GitHub README: https://github.com/pettarin/penelope
