You probably will not believe me, but I witnessed a Hong Kong release of Biohazard 2 Prototype for Sega Saturn with a stamped label on the front saying &#8220;none retail purchase, this version is for marketing research only&#8221;. It was packaged with a special box, similar to artwork shown on bio flames. I didn&#8217;t play it I just glanced over, it had a white label coated with red/black writing on the left-hand side, showing that theirs a packaged 1MB ram cartridge inside. It looked very nice; it was probably the 85% completed version.  All I can say it was sold with a lot of Hong Kong manhue (manga) comics for resident evil 1 &amp; 2 alongside the Japanese Saturn release within July 1997.
