MGS2 Substance?? HELP!!!!

[infidelity]

I transfered MGS2 Substance to my pc's hd, and I know that the size is roughly 6.4gb. But, the files are all data files, and some of them say, disc1-0, 1-2, 1-3, etc then the others are called, disc2-0, 2-1, 2-2, etc, etc. I attempted to burn the first disc-1 files with the default.xbe file, I burned it as a data file, on one DVD+RW, anit was converted to an xiso image, both with no success. I have no room on my Xbox HD to throw this game on there, but, is there a way to play the game on one disc, is it possible to play all of disc 1, withou disc-2 files on it??? And, I noticed that the original game was on there, I don't want that, I only want the vr misson games, if that helps. Thanks for your help.
