I have a mission, to break the world wide Contra highscore.

Contra is a NES game released in 1988. I have been playing it since I was 3. Up until last Christmas 2011, I could only beat the 3rd level; for my 1st time ever. Now I have beaten the game multiple times in a row. Each time I play it I get better. In one day my highscore improved by a million. At a rate growing that fast I hope that someday I hold the all time highscore, even though I have no clue what it is. My current highscore is 3855600. If anybody knows what the current highscore is can you please tell me?
