Authentic Japanese Game Boy Advance cartridge — Bokura no Taiyo, known outside Japan as Boktai: The Sun is in Your Hand. This cult-classic Konami action-RPG produced by Hideo Kojima features the famous built-in solar sensor that detects real sunlight to power Django's Gun del Sol against the vampires. Genuine cartridge, cleaned, tested and working — region-free, so it plays on any GBA, GBA SP, Game Boy Micro, or DS/DS Lite worldwide. Sold as cartridge only; on-screen text is in Japanese. Please note the internal clock/save battery is original and not guaranteed given the game's age.
