Well, without messing with anything, compatibility is mostly the same. Except that disc swapping is more reliable for Vita (Fear Effect 1&2 are examples of this).Do we know if there's any compatibility differences between PSP 6.60 POPS and PS Vita POPS?
We know that PS Vita POPS is based on PSP 6.60 POPS but it's very heavily changed (specially sound emulation is completely reworked).
But I am still not sure about them having the same exact compatibility. What do you guys think?
Otherwise, Vita's POPS has a lot more configurations to apply, so some games like Worms Armageddon work fine with a config file, whereas it does not get past the intro on PSP.
Also, Crash Bandicoot 3 fixed the swirl effect that occurs when entering and leaving a level, because Vita's POPS has an updated internal config. That shouldn't matter by now however, as I ported most configs from Vita to PSP (except those that rely on Vita only configs).
