Dumping VC games on Linux

[Scoopta]

I'm looking to obtain wads for majora's mask and ocarina of time. Everything I've read involves using showmiiwads which only runs on Windows. Is there a way to dump games on Linux? They're installed on my SD card although from everything I've read I'll have to copy them back to my wii and do a NAND dump which isn't that big of a deal but if I can get them off the card without doing that I'd be happy with that too.
