Hi everyone, this is my first time trying to set up an R4 flashcard. I recently bought a Nintendo 3DS along with it, but after searching online I couldn’t find any guides that use this specific R4 model, which made me wonder if it might be too old.

Does anyone know what I should do with this cartridge or if there’s a guide specifically for it? Also, does it work with 3DS games, or only with DS games?
