Well, until PKLATAM Jirachi was distributed in Mexico, events were not publicly advertised with banners and the internet, you just needed to read the Nintendo Magazine and head to the EGS (Electronic Game Show, sort of mini E3, which started in the year 2001) and the Nintendo staff would give you a Jirachi, a Deoxys or whatever the current event (I think we got Eon ticket too).
Anyways, before that, I think Mexico was the easiest place in the world to legally obtain a Mew or Celebi during the GBC era, you just went to the editorial office on a saturday with your gameboy and that month's magazine and Voila!
IMHO, Nintendo (of America) started changing their politics regarding latin america when Reggie Fils-Aime became their President, and publicity and events are getting more and more common here, which then led to the propagation of events in the continet.
However, that Jirachi up there is the only downloadable "IRL" event we got for the DS, I must assume that events like SPACE C, TRU, Movie#, etc. will never be applied or redistributed in Latin America. But, as stated above by NickofTime, it is just a game, we did not sign a contract neither it is a human right that granted us those special Pokemons ... it is just luck (and marketing)
