Personally, I think it would be easier to use a HBC app called CleanRip. Assuming you have a Melee copy, you can get a Melee ISO from your Wii that way.
I would have, but I'd already downloaded a gig of the ISO. Either way, I'm playing it now, after a panic when realizing my SD was too small (1 gig), I bust out an HC 16 gig black sandisk card and went through it. It's fun!
That being said, it was a pain to install.
Oh well, I'll be sure to take my Wii around with me now when I play with my dear friends :D
Edit: OH BABY PLAYING THIS FEELS GLORIOUS
GANONDORF IS GOOD MARIO IS GOOD YOSHI IS GOOD FALCON IS GOOD
EVERYONE IS GOOD I EVEN COMBOED MARTH HARD WITH KIRBY AND even the same old characters feel great! Never have I had a more satisfying pillar (except against friends) when I realized Yoshi's grab was so good and the CPU kept using it I spotdodged and rekstroyed him. Not that CPUs are hard to predict, mind, but it felt like I wasn't just taking cheap advantage of Yoshi's grab being crap (because it's not).
Also, mixing up Ganondorf's options when coming down is now fun. Am I going to stop, or wizard's foot, or what? I had a great time with Roy too, he felt like he should. Dinky moves leading to lots of hits leading to a climax (3/4 of my combos ended in f/u-smash). Zelda's lightning kicks and Luigi's chop felt usable. I had a few neat combos with the tilts on Zelda, but d-tilt didn't have the range I wanted, and getting out was as easy as ever with her floatiness. Walling was fun with her too, and capitalizing on the mistakes of the others doesn't feel cheap because, again, there are no ultra stupid laggy moves that make no sense.
WHY DIDN'T I GET THIS SOONER
I know the answer. Hacking the Wii was too intimidating. I didn't want to take half the day (and I did take half the day) to do everything. But, I'm having fun with it now, and that's what matters most.
