spanish-spanish dict (where came it from?)

I once had on my PB a nice es-es dictionary, and I lost it upon factory reset. It was a comprehensive one giving various latin american usages, and I can't recollect where I downloaded it from. Does someone have a pointer to it? I haven't been able to locate it across the threads...
I also remember a russian repository of all dictionaries ported to pb, which I haven't refound. Does it still exist?
