Super Mario World/Back Door

What a pleasant surprise! Now you can take half the walking off from this, its still dark, but of cousre you got a light to help, well, once you activate it, kill all monster and theres a Save point by Bowser's door, to where you fight the Dastardly one, all you do is throw his MechaKoopas at him when you jump on the MechaKoopas (dont spin jump or you'll have to wait for Bowser to throw new ones = \ ), wait till Boser dissappears for 30 seconds while dodging his little fires and Toadstoole will appear and hand you a mushroom (if you lost both or 1 power up)and Second round will happen, first Bowser will pull out 2 Giant Marbles and you jump over untill he throws his lackeys, do what you did last time on First round, now again, wait till he dissappears when he gets hit and dodge the flames....But wait until 3rd round, he will CHASE YOU by pouncing on the ground, this time he's furiouse, he will pounce to you and you have to shoot his lackeys, of course, the when you do that, congradulations! You finally beat the game!
