Double Dribble, Konami
This is a really BADLY implemented basketball game.  The way it marks the 
controlled players seems to be with even more flickering than usual- making it 
very hard to operate at all.  Also, there are really BAD digitized video 
segments (if you can call them that) of something doing slam dunks, etc.  This 
game is so bad it is almost funny.

Defender ][, HAl America
This game is an excellent port of the classic StarGate (with no relation to the 
movie of the same name) arcade game.  It is mindbogglingly hard, and with the 
new hardware it performs astoundingly well at a slightly higher speed.  The 
control is also better then the Atari (400) version that I own, making it much 
easier to die while trying to steer.  The Smart Bomb feature has been placed 
where it can be easily accessed, at the A button, and the guns (which seem to 
have replaced the laser cannon of Defender 1 for the Atari) perform smoothly and 
accurately.
