> Halo, one of the decade's most renowned video game franchises, has finally found a home on the Atari 2600! In this special version of Halo, you play the role of Master Chief as he battles his way through 64 screens! Locate weapons and power-ups that will help you defeat increasingly aggressive enemies! Watch for special Shield power-ups that will give you a second chance when engaging an onslaught of Elites! Halo 2600 was programmed by Ed Fries in just 4K of space.
Its the full game to my knowledge, you can thus play from start to finish. 
a demake of Super smash Bros, featuring 6 playable characters. Which are: Mario Kirby Link Pikachu Vaporeon Megaman
