I've beaten the game, twice now, only have extra items and maybe a scan or two to get (though I think I missed one early on.  Crap).  Anyway, I have a question regarding scans: why is it that when you beat Metroid Prime and save after the credits, it doesn't save the scans you acquired?  I mean, I scanned those phazon lizards, the fission metroids, and both forms of Prime, but playing through it again I had to re-scan all of them?  What's up with that, and how do I keep my Prime scans?
