My friends over at “Adventuras en La Marca Del Este” have written to inform me that they are hard at work producing a Spanish retro-clone entitled—what else—Adventuras en La Marca Del Este. It will be a Basic D&D retro-clone similar to Labyrinth Lord but “with a few changes” according to Pedro Gil of “Adventuras en La Marca Del Este”. It will be a boxed set release that includes a 150 pp. rule book, a set of dice, and a three-panel referee screen. An English-language translation is being considered.
Unfortunately, my Spanish is atrocious and Goggle seems to be having difficulty rendering the site into something I'm literate in so I have little else in the way of information. Some more details can be found here. Feel free to leave a comment with more information if you have more than a passing acquaintance with Spanish.
Pedro provided me with some sample illustrations from the work including these LoTR inspired pieces, a cover piece inspired by Elmore’s take on the Red Box, and a female cleric bound for holy smiting.
