I had a similar problem until I noticed that I was attempting to save to the Ext Rom 2 and not the mini SD card. The messanging application on the ppc-6700 does not see the mini sd card and enable storage to the mini SD card unless the Ext ROM is hidden! Try this registry fix (swiped from the other Mario forum). It worked for me :P

Using Registry Hack to unlock hidden ROM:

HIDDEN: (Original Setting)
[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\ TRUEFFS_DOC1]
"Bootphase"=dword:00000001
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ TRUEFFS_DOC1]
"MountHidden"=dword:00000001

SHOWN:
[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\ TRUEFFS_DOC1]
"Bootphase"=dword:00000002
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ TRUEFFS_DOC1]
"MountHidden"=dword:00000000
