Brawl data partition = bad?

[linkbean]

I've been trying to load custom textures into a Brawl ISO, but every time I extract the partition, replace the files, and put the partition back in, the partition always ends up 'bad.' The ISO won't load in Dolphin after, and it makes the ISO unusable. Help?

It's because you can't just replace the partition
you can only replace things one at a time but not the whole partition.
I tried what you did before and it didn't work

Dang. Surprised no one has found a way to put the whole partition in itself, I found guides but none have worked for Brawl. It's a bit tedious to replace 100+ items in my case, so looks like I'll keep searching....
