I now just saw that I still have some FF games on my HDD. But I will list everything here, because I don't have the perspective anymore. So I have:

- Final Fantasy I, II, III, IV, V, VI (NTSC English version, and I & II are bundled in one image)
- Final Fantasy Anthology (Europe edition PAL)
- Final Fantasy Anthology V & VI
- Final Fantasy Chronicles IV

So what are the differences here?
