I have uploaded the pali-to-english dictionaries in Kobo (dicthtml-pi-en.zip) and StarDict (pi2en.zip) formats here:
If anybody would like any of the other languages we have in the lookup tool, please let me know. The Kobo one works fine but you have to replace one of the ones on the Kobo itself in (hidden file) .kobo/dict and give it the same name.
If you want another format, please let me know.
