Wiithon only copies 0.34GB/4.4GB to the WBFS partition

I was very happy to find your Wiithon utility -- it looks great. However, I am having a problem where Wiithon does not seem to copy the whole game (ISO) to the external hard drive. I've tried stable 1.1 and development 1.21 versions -- both installed successfully. I successfully formatted an external hard drive connected to my laptop to WBFS. Wiithon recognized the ISO file, downloaded the appropriate cover art and information -- but ultimately only copied 0.34GB of 4.4GB (Super Mario Bros Wii) to the external hard drive with WBFS partition. I plugged the drive into the Wii and used USB Loader -- it recognized the drive and showed the Super Mario Bros Wii game entry -- but failed to load it (of course, since it was only 0.34GB). Am I missing something obvious? Any ideas?

EDIT: Was just playing around with the ISO and I noticed that it contains an "UPDATE". In other words, the ISO contains two "PARTITIONS"... 0 and 1. Partition 0 is the game/Wii update. Partition 1 is the game itself. Is it possible that Wiithon thinks Partition 0 is the game -- hence why it is only 0.34GB on the hard drive?

Thanks so much for a great program... it is always very exciting to see development like this for Linux users.

Best regards and thank you in advance for your help!
