Metroid Prime 3: Black Screen at Save and entering Ship

[Danky-Di]

Hi Guys,

after defeating Ghor and acquiring the Plasma beam, I entered the (damaged) ship to save.
The save screen (telling not to shut down the device etc.) never vanished and after minutes of waiting I reset and used a state save.
Unfortunately, I am now completely unable to use a save station or even to enter the ship.
When trying to enter the ship, the game briefly stutters and shows the ship interior for some frames before fading to black.
The music keeps playing, though.

Anybody encountered this issue and has a solution?

Thanks

Update:

at first, I suspected a screwed up save file (sd card). So I tried loading a state save way before Ghor and saving and entering the ship worked without a problem.
But after defeating Ghor, the same issue arises...
