missing a "\title" somewhere...

Yes I think that is the problem. But any other game is saved correctly.

"a7432ea241693787" is apparently some invalid hex (for a wii title). curious....

Its real... here some screen shots:
"open wii save folder" and the empty opened folder:
1 wii save folder.jpg
the real save folder:
2 real save folder.jpg
screen shot of the game before main menu:
3 screen shot

what program did you shrink the iso with? the title id is not where dolphin expects
it to be

cause is corrupted or shrunk in an unusual way iso

from http://code.google.com/p/dolphin-
emu/source/browse/trunk/Source/Core/Core/Src/IPC_HLE/WII_IPC_HLE_Device_FileIO.cpp

std::string HLE_IPC_BuildFilename(const char* _pFilename, int _size)
{
char Buffer[128];
memcpy(Buffer, _pFilename, _size);

     std::string Filename(FULL_WII_ROOT_DIR); 
     if (Buffer[1] == '0') 
             Filename += std::string("/title");     // this looks and feel like 

a hack...

     Filename += Buffer; 

     return Filename;
