hi i just downloaded the new metroid game for wii iso and its 7.92 GB and my disk only holds 4.7 gb can i make it smaller in any way with a program (not wiiScrubber because it only makes it smaller if i put it in a zip and i can't put a zip on a dvd-r) so can you help me or give me a download to a iso that has already been shrunk (sorry for poor spelling)
