Well, I can't prove anything since I sold off my Neo Pocket collection (including U.S. clamshell versions of Bust-A-Move, Baseball Stars, and KoF:R-2) and I've never been into collecting pictures of box variants even though I've seen all the others on eBay at one time or another.

Maybe check at the Neo-Geo.com pocket forum if that's still active, a few years ago when I was posting there, there were a few other members who had some of these U.S. clamshell releases. One guy had all of them, I think.
