You got the game soul silver from a garage sale even though the game was severely damaged and glitchy

When you were home you started playing and you noticed every time you took out the map there was a extra city that there was no physical way to get to, you gotten through most of the game and you were walking through lavender town when the game started gliching again and there was a trainer who looked dead with no eyes or limbs and their just staring off into the distance
