considering there is no actual data in this image, im sure it doesn't break any rules here.

http://www.hivclan.net/stuff/HALO-mini-image.rar (20mb)

its a mini image, just mount this and you don't need any no cd exe or anything else, this tricks the game into thinking the actual cd is in the drive basically.

plus, since its only 20 mb, you wont waste the space you would if you were to make an actual image.
