Sorry, I should have put that in my previous post.
Standard (straight-off-the-disk) size: 2.48GB (2,671,837,184 bytes)
Shrunk size (with ZZ_Dummy.bin): 1.53 GB (1,647,888,384 bytes)
Shrunk size (without ZZ_Dummy.bin): 1.34 GB (1,446,985,728 bytes)
I dunno if the ZZ_Dummy.bin file is truely needed, so I'm gonna try an iso without it. I'll edit my post after I get it all done and tested.
Edit: Okay, built and quickly tested the iso without the zz_dummy.bin file, and it seems to run just fine.
Hope that helps you some.
