a comment from someone who found this hidden message in Space Harrier mkIII back in the day: "unfortunately, I was the 12th person to write in, but one of the staff (I forget who, sorry) sent me the invite card from that year's AOU…it might still be at my parents' house…"🇯🇵 
this message is present in the Master System version too afaik, it appears when every entry in the high score table reads "ERI"
another one! "I found it & sent in a letter; I figured they would've already received 10 entries but I wrote a buncha stuff…I mentioned the Outrun AM show card & they sent one to me, good ol' Sega! the code wasn't in any of the magazines, I was so happy"🇯🇵
one more: "I mailed in the game clear code and they sent me a "running Alex Kidd" pencil tin and a brass Outrun logo keychain"🇯🇵
(if you've never seen that pencil tin, it looks like this it was a sweepstakes prize, 10k made)
