Game you are most proud of having beaten

[chuckleslovakian]

Blast Corps-I have no clue how long it took me to beat this game. Yeah, the game practically demands perfection on over 100+ random levels.
Mega Man: Dr. Wily's Revenge:The original for the gameboy. Not too bad until the end. Then for the end, you have one stage to beat. Then you have to fight every boss you have already fought in the game. Of course there is another random boss after those. Next the game throws another long level at you. Then you finish up by fighting Dr. Wily. Of course, if you lose all your lives you have to go back to stage 1. For some reason the game decided not to put another save point in between these 2 levels making it extremely painful.
