[citation needed] Unusually, Dantas writes in both the Romi (Roman) and Devanagari scripts of Konkani, and also in Marathi.

It lists and describes all the films ever shot in that language from the first in the 1950s or thereabouts till very recently.

He has also translated two books: children's author Anita Pinto's Espi Mai Is Stuck Again (as Espi Mai Porot Xirkoli) and artist-writer Angela Ferrao's Fuloos Plays With the Sun (as Fuloosachi Husharkai).

[11][12] Dantas has been described as an "avid collector of Konkani film memorabilia"[13] and is credited with having had a role in the restoration part of the first (and popular) Konkani film Mogacho Aunddo (Love's Craving) (1950), by Al Jerry Braganza.

Media reports said the reels of the film were handed over by a relative of Braganza (his nephew, Angelo Braganza) to Dantas in 2010 during the release in one of his books, and Dantas, in turn, passed it on to prominent Konkani film director Bardroy Barretto, who managed to get the job done.
