However, restoring these assets was far from simple. The main technical challenge revolves around the PSP's unique file structure.

The development of a functional patch hasn't been without its technical hurdles. The primary challenge is the PSP's file allocation system. The system uses a Logical Block Address (LBA) table, which acts as a master index tracking the precise location of every file within the game's ISO. When files are swapped or repacked, even swapping the English title screen for the Japanese one, the LBA table can become inaccurate. This causes the game to crash, typically after the intro movie. These technical issues, combined with the game being a portable port of an already localized title, have led some in the community to question if a full-scale patch is necessary. Nevertheless, the dedicated tinkering of enthusiasts continues.
