Emulator

Game Name?
Super Smash Bros. Brawl and probably Mario Kart Wii and Wii Fit Plus

What went wrong?
In Super Smash Bros Brawl, the disc have 14 partitions (one "update" partition, one "data" partition and 12 Virtual Console partitions, one for each Master Piece). However, the Filesystem tab show only the "update" and "data" partitions, even if the game have more partitions.
I'm not sure, but apparently Mario Kart Wii and Wii Fit plus also have a 3rd partition containing the channel installer, that also doesn't show up in the Filesystem tab.

What did you expect to happen?
I expected Dolphin showing all partitions of the disc, allowing me to extract files, check partition integrity, etc.

What steps will reproduce the problem?
With a working dump of Super Smash Bros Brawl (unscrubbed and uncompressed), go to the Game Properties and then switch to the Filesystem tab. You'll see only 2 partitions, but the ISO have 14 partitions (one "update" partition, one "data" partition and 12 Virtual Console partitions, one for each Master Piece).
I'm not sure, but Mario Kart Wii and Wii Fit Plus should list an additional partition with the channel installer too.
