Link, I’m always waiting for you…
Buyatari has some cool promo items and a SNES-CD proto-pad!
DTL-H5000, looks like a PSX DEV serial. But I think that the differences between the PlayStation project and the SNES-CD at one point were almost inexistent.
Sone cool items from Japanese (love?) hotels:
Sakurai Dazzla 007 Pong Hotel Unit
Other items:
NES Sharp TV
NIB Yaroze
SNES kiosk
StarFox Super Weekend
Jaguar DEV kit w Alpine
Nintendo & Dreamcast promo bags and cases
