Cannot save when memory use exceeds 1.5gb

[plumcakk]

Been using svn2100, but for all the builds I've tried, the same thing happens. The longer I play, the more memory is used, until it reaches about 1.5gb, when I can't save. If it hits 1.6, the OutOfMemory error or whatever it's called comes up and the emulator crashes.
