Blizzard has Blackthorne free for download direct from their site. You could also use their beta game client program to download the game.
From wikipedia:
Blackthorne (Blackhawk in some European countries) is a cinematic platformer video game developed by Blizzard Entertainment. It was released for the SNES and MS-DOS in 1994, and with enhanced graphics and a higher color palette for the Sega 32X in 1995 and for Mac OS in 1996.
Now they just need to release Rock n Roll Racing and I’ll be happy.
