we have just bought the ps2 vanadiel collection too but we managed to install it on our ps3 ( lucky us ). however even so, it does take nearly half a day to FULLY install the WHOLE collection. Bear in mind that the FF collection edition comes with all 4 expansion packs and each expansion packs does require at least a couple of hours to be installed. This ps2 2008 collection only uses ONE code to install all 4 expansion packs. As I recall, I installed ours in the morning and in the late afternoon, it was finally FULLY installed. If for some reason, you need to step away from the PS2 and switch it off, when you switch it back on to continue installing, the file will NOT re-install from where you left off initially, it will FIRST CHECK all your FF files from the beginning ( which might takes half an hour or longer ) BEFORE continuing installing from where you left off.
In conclusion, you might need to spare half a day ( will probably be lesser ) to finish installing the whole ps2 2008 collection especially since it is the PS2 machine you are using. Hope this helps and good luck. BTW you might need to move the joystick now and then so as not to freeze the installing process ( not sure if this is so in your case ).
