I have googled, I have attempted a search here, which isnt the easiest

grr. Oh well, my question is, are there any differences in the psn versions of ff7 or ff8 other than the fact that you dont need to use a disc?
Another question is, the Chocoworld, did they implement some way of using it? or is Apocalypse and Minimog and such just completely unobtainable now?
