1.Metal Slug, lots of extras and too $$$ on home Cart.
2.Twinkle Star Sprites, great two player shooter and too $$$ on home Cart.
3.Iron Clad/Brikinger, CD exclusive and a very good horizontal rendered shooter, but still $$$ even for CD. <IMG SRC="smilies/ohno.gif" border="0">
4. Samurai RPG, great art and music, CD exclusive.(Need to know Japanese or be very good at trial and error).
5. Pulstar, one of the best shooters any where and relatively inexpensive on CD.
All the games above with the possible exception of Samurai RPG do not have distractingly long loading times and work well on CD IMHO. <IMG SRC="smilies/biggrin.gif" border="0">
