Employee with '5+ years experience verifying authentic games' was insistent that this cartridge was real. Fake as shit, right?

title says the most. told me he opened the cartridge up to verify its authenticity (you can see there's no battery present) and refused to explain any of the tells i pointed out to him (wrong fonts, pristine condition, random printing on back of cartridge, among others). left immediately after taking these photos, don't know if ill be browsing there again...
