Wobbling chainrings/spider

I have a Shimano Nexave crankset from 1998, it only has about 6000 km on it. However, the chainrings
developed a sidewas wobble some time ago. Cranks feel very solid with no wobble at all, and I've
checked the chainring bolts too. Pictures:

For all I can see, the spider is connected with the crank via a toothed interface, which apparently
has become somewhat loose, causing the wobble. Can anyone confirm this? Maybe I could take it apart
to verify it myself... :-/

Is it possible to fix this? Am I in for a new crankset or some other parts? :-(

That looks like the spider was pressed onto the crankset. If it's loose, you're probably looking at
a new crankset, and possibly a BB depending on what crankset you go with.
