Seiken Densetsu 3
Due to the release of Collection of Mana and the 3D Remake, I can't host the ROM here. Rather, the button below directs you to SNES collections at Internet Archive. Click here if you need directions with that. If Internet Archive doesn't work out for you, I have more options in my links.
Note that when you're looking for the game, you need to search for “Seiken Densetsu 3” not “Trials of Mana”. Also, it would be in Japanese (only). You need to apply the English patch below to make it English.
