【Product Overview】 This is the original Nintendo Game Boy (DMG-01) released in 1989. It comes with the valuable original box, instruction manual, and warranty from that time. This is a "matching serial number" item, where the serial number on the back of the main unit matches the number on the warranty (G37330473). I believe this is a valuable piece for collectors. 【Set Contents】 • Game Boy本体 (DMG-01) • Original Box • Instruction Manual (DMG-GA) • Warranty (Matching Serial Number) ※ Software, batteries, and headphones are not included. 【Operation Check & Condition】 • Power On: Confirmed (see photos) • Software Loading: Confirmed • Button Operation: Confirmed response from the D-pad and all buttons • Sound: Sound output from the speaker confirmed, volume adjustable • LCD Condition: It starts up, but there are vertical line defects (display issues) on both sides of the screen. Please be sure to check the photos. 【Appearance】 • Main Unit: Due to its age, there are some scratches and minor dirt, but there are no major cracks. • Outer Box: There are scratches on the corners and some damage, but the shape is well-preserved. • Battery Compartment: No signs of battery leakage, and it is in relatively clean condition. 【Notes】 Please purchase only if you understand that this is an electronic device from over 30 years ago and that there are some defects in the LCD. Would you like it for repair, parts, or as a collector's item? It will be carefully packed with bubble wrap and shipped via Mercari delivery. Instant purchase is OK.
