Anyone have any idea if this is actually a legit promo copy of KOF 94 on NGCD? I'm not at all interested, but if legit I've never seen this in my 20+ years in the Neo scene. There are 3 on Ebay for over $5000!

I can't speak to the Neo Geo CD specifically, but I can say I have seen similar US promo games ranging from Sega CD through Dreamcast where the disc is pressed as a retail game, but there is no silk screened artwork. I can't really see the inside of the disc particularly well, but assuming this isn't a label-less Hong Kong silver bootleg, it seems real to me.
However, the fact this comes with the retail insert and manual seems suspect. If those originally went along with it, they probably would have had the disc art ready too. I would guess those were matched to this long after the fact to make the auction look more enticing. This is all speculation though.
