I was wandering the web and stumbled onto something unexpected. A glimpse of a Korean box for Sonic 3D Blast, except it's labeled Windows 95/98! The Mega Drive version is already listed on Sonic Retro. https://bbs.ruliweb.com/game/2928/read/3353461 Unfortunately only the side of the box, neither front nor back. And the page's screenshots are of Sonic Heroes instead. (which by the way has Korean text on PC even in the west) Entering "소닉 3D 블래스트" plus "windows" into Google image search doesn't turn up much helpful.
