Gamepad -vendor 1949 Product 0402- __top__

"Gamepad" might be controller, joystick, or input device. "Vendor" here is part of a title, so maybe change "Vendor" to "Manufacturer" but wait, the user said no changes to proper nouns. Wait, "Vendor 1949" is part of the title. Since vendor here is part of a proper noun structure, maybe it's considered part of the term. The user said proper nouns remain unchanged. Hmm, but the instruction says "No changes to proper nouns." So I need to check if "Gamepad Vendor 1949 Product 0402" is a proper noun. It might be a title, so the words might be part of it. But "Gamepad" and "Product" could be common nouns. Wait, if "Vendor 1949" and "Product 0402" are part of a title or identifier, maybe they should remain. Need to be careful here. The user didn't specify avoiding changes within titles, only proper nouns. Maybe the user means not to change names of specific companies or products. Since 1949 and 0402 are IDs, maybe they stay. So "Gamepad" can have synonyms. So "gamepad" →joystick. Then "Vendor" is part of the title but in the text earlier it was just "vendor ID". Since it's part of a title, maybe keep "Vendor" as is. But the user said "No changes to proper nouns." So if "Gamepad Vendor 1949 Product 0402" is a proper noun, maybe not change. Wait, but the user wants all words replaced except proper nouns. So if in the sentence, the words are common nouns, replace them. For example, "Gamepad" is a common noun, so replace. "Vendor" is a common noun, so replace. "Product" is common, replace. But 1949 and 0402 are numbers, part of the ID, so leave. So in the title, it would be: controller supplier 1949 merchandise 0402. But maybe the user considers "Gamepad Vendor 1949 Product 0402" as a title where "Gamepad", "Vendor", "Product" are part of the title and should be replaced. So process accordingly.
