• Inspect the detailed log around the error line for preceding warnings or stack traces (file paths, errno).

• FST stands for Filesystem Tree. In the context of GameCube discs, the FST is a special table of contents stored on the game disc. It lists every file and directory present, along with their offsets, sizes, and attributes. Without a valid FST, the game cannot locate its own assets (characters, levels, sounds, etc.).
• IOSFS (I/O System FileSystem) is a component within Dolphin that emulates the low-level file I/O operations of the GameCube’s IOS (Input/Output System). When Dolphin needs to read or write to the virtual disc’s filesystem, it goes through IOSFS.
