To the op, it appears to be super famicom cartridge, which could mean it's Japanese. I could be wrong, as I don't know which country's got the Famicon/super famicom and which ones got the nes/snes. But I don't think it's a bootleg copy... (Keep in mind that I didn't watch the whole video, just skimmed it, as I didn't feel like listing to some guy talking hehe).
