It's because Dissidia is meant to be played on fw 5.01 or higher. If you save it on a lower firmware, saved data won't be loaded by 5.01. Viceversa, if you save on 5.01 or higher, lower fw (and cf, of course) won't load the data. So, it means save data here in gamefaqs has been made on 5.01 or higher...try and update your firmware, but be aware you may lose some of your savegames, i.e. Crisis Core is meant for 4.02 so your 3.90-saved game won't work if you update your psp.
In Final Fantasy VII, If the player casts Barrier and MBarrier on the Adamantaimai before its first turn, the Adamantaimai will try to use Cure. For an unknown reason, the Adamantaimai will also try to use that spell once it has the Barrier and MBarrier statuses. However, the Adamantaimai does not have Cure in its attack list, so the game will either freeze, crash, or do stranger things.
Sometimes the game will give the battle message: "Data Error - Scene: 179/Code: 32 - Push L1 + R1 + Select for Reset", and this will repeat over and over again. The player cannot do anything but push those buttons to return to the World Map.
SDA does something similar even though there aren't that many people on the site, though the amount of overseas people is a problem, as there are more here than SDA. One way to solve this is if people are willing to contribute bringing some over. However, we'd need to have something good to meet up for, like a convention or party or something, and the place needs to be convenient for everyone that has a possibility of making it.
Hmm I think I know why...Google owns Youtube and are limiting its use for Firefox and IE users, but Chrome users have freedom. Kinda like how I heard that people get faster uploads with Chrome than they would with FF or IE.
