Thanks for downloading Super Spartan Bros.!  
This is a hack of Super Mario Bros. for the NES.  It changes everything in the game into something from Halo.  I had been wanting to do a hack for awhile, but never could decide what to do.  One morning I woke up and realized: No one has done a Halo-Mario hack yet!  So I went to it.  SMB Utility would not work on my machine, so I did all the levels with yy-me.  This caused a few glitches that I could not fix (purple bushes in 6-1) as well as platforms that randomly do not appear in various other levels.  But this is my first hack, and I've spent a lot of time on it (at least 75% of which was play-testing), and I'm going with what I got.  I'm gonna make a list of what everything is supposed to be (three colors is not a lot to work with, so you may not be able to guess everything right away)

Mario - Master Chief
Luigi - Blue Spartan
? blocks - Ammo Boxes
Mushroom - Spartan Helmet
Star - Hidden Skull
Coins - Ammo Clips
Coins (as they come out of boxes) - Grenades
Fire Flower - Energy Sword
Fireballs - Grenades
Toad - Marine
Princess - Cortana (albeit, she's green)
Goombas - Grunts
Koopas - Prophets
Spinies - Drones
Jumpng Fireballs - Drones
Pirahna Plants - Elites
Hammer Bros - Elites (they throw plasma grenades)
Lakitus - Prophets (in a hover chair)
Fish - Flood Spores
Bloopers - Flood Carriers
Buzzy Beetles - Monitors
Bullet Bills - Sentinels
Cannons - Grunts (in stationary guns)
Background Objects - Warthogs and Covenant Com Nodes

Thats everything I can think of at the moment of my writing this.  
I'd like to thank a few people, Googie for answering all my questions (I wouldn't have been able to make the title screen without his help), my friends John, Nick, Joel, Ju, Sarah, Tyler, and Shawna for the encouragement all along the way, and my fiance(spelling?) for ideas and encouragement as well.
Anyways, I worked hard on this, and I hope you all enjoy, Halo and Mario fans alike.
