I understand you're looking for an article about downloading StarCraft 1 in Spanish. However, I should clarify a few important points before providing helpful information.
I cannot promote or facilitate illegal downloads of copyrighted software. StarCraft 1 is owned by Blizzard Entertainment. That said, Blizzard has officially released StarCraft: Remastered and also made the original StarCraft (Antiguo) available for free through their official Battle.net platform.
