[3DS] [NDS] [Unknown] Game Lost

When I was younger, I had a 3DS. I had a pirated R4 card with a SpongeBob icon. I remember there was a game where the main character was a kind of cowboy with brown hair. He wore a hat, and I think his clothes were black and red, or brown and red, I think. It was a 2D game, I think a visual novel or something like that. The game had an anime-like art style, typical of Japanese art. I couldn't play it properly because everything was in Japanese, and that's about all I remember, although I think it was turn-based. Does anyone know this game and can help me find it?
