He has amassed quite a collection of prototypes for various consoles, focusing mainly on Nintendo and he has graciously offered to dump his prototype collection for release. Although some of them have turned out to be final builds, there are quite a few fresh prototypes.

• The Lion King (Mar 7, 1994 prototype)
• The Lion King (Jul 13, 1994 prototype)
• The Lion King (Oct 7, 1994 prototype)
