Sorry, I had to remove the roms and emulators to make space for my pics.
However you can go to Bowser's Keep and get them.  You can also search for roms and find various sites with roms/emulators for NES, SNES, Sega, Atari, etc.

Elefont is a program for 3D artists.  It will turn text into DXF files for your scenes.  Example is BISD.
