You bringing up emulation reminded me of another reason I am leaning toward starting collecting Saturn stuff again instead of something else. Its games aren't available anywhere else legally. PS1, PS2, PC Engine, and Neo Geo games are coming to PS3. Essentially everything pre-32-bit, along with the N64, is trickling onto Virtual Console. A lot of big DC games are coming to PSN/XBLA. GC games are coming to the Wii U. But the Saturn stuff is largely stuck there except for a couple recent Treasure XBLA ports.
