Ul.cfg Ps2 Editor

Let’s peek under the hood. A typical UL.CFG is a binary file, not human-readable in Notepad. Its structure (simplified):

[Header]
Magic bytes: "ULCF" (0x55 0x4C 0x43 0x46)
Version: 0x02
Entry count: N
[Entry 1]
Game ID (10 bytes, ASCII, zero-padded)   e.g., "SLUS-21331"
Game name (128 bytes, ASCII or Shift-JIS) e.g., "Shadow of the Colossus"
Startup flags (1 byte)                   e.g., 0x00 = normal, 0x01 = Mode1
Disk number (1 byte)                     for multi-disc games
Unused / padding

The editor’s job: parse this binary structure, let you tweak fields, and rewrite it without corrupting the table.
