Topic: [psp] Star Wars - Battlefront II (Japan)
This could possibly be overdumped, not 100% sure without owning the image.
The Star_Wars_Battlefront_II_JPN_PSP-Caravan dump is underdumped by 16 sectors, no files are truncated, the actual size of this dump when fixed is 711,360,512 bytes.
Which if this is supposed to be the same image, then maybe the redump version is an overdump.
The SPICE must flow.
