The script directory (contained in the [[master file table]]) contains both [[bytecode]] scripts and strings used in the game. It's layout is different than the other directories in the MFT. The <code>build_date</code> is likely referring to Konami's authoring tools, and not to the game itself. The entire script directory and its contents may be aligned to a 1-byte boundary, as the game will only issue 1-byte reads to it. However, in practice it is still aligned to a 4-byte boundary.

struct script_directory {

u32 ~~unknown~~; // ~~0x3ea8eae6 in Boktai 1 (U)~~

u32 build_date; // seconds since unix epoch

script_entry script_entries[];

// NOTE: offsets.script_data points here

u32 special_script_offset; ~~// unknown...~~

u32 special_script_offset;

// NOTE: script_entry.offset is relative to here

// ~~Unknown data, including the "special script"~~

// NOTE: special_script_offset points here

u8 ~~unknown~~[?];

u32 special_script_size;

u8 special_script_data[];
