Mr. Hamman taught me a thing: https://twitter.com/hyasuhi6/status/1601339674500665344 Calling Model 3 technical experts: former Sega man Yasuhiro Hayashida claims there is a hidden code in Harley-Davidson & L.A. Riders, which when entered during the attract sequence will show a credits screen. It's a bit above my pay grade - all I can confirm is that pressing random buttons doesn't help much. It seems the sort of thing you guys could crack - any ideas?
Might be worth checking to see if its on both regional releases, or only in the Japanese release considering it released a month earlier (or only in standard or deluxe cabinet variations).
