Crash 2 Return/Error Codes

Engine assumes codes range from 0xFFFFFF01 to 0xFFFFFFFF. A special return/error code, 0, is used in certain GOOL interpretation functions (event, state change, animation change) to indicate that the function failed and/or that interpretation should continue.

Code	Meaning	Additional Notes
0xFFFFFF01 (-0xFF)	No error.
0xFFFFFF02 (-0xFE)	Error finding specified file.	"File" includes entries and disc files.
0xFFFFFFE5 (-0x1B)	The specified object state is invalid.	For example, when an object's subtype corresponds to state 255 (invalid).
0xFFFFFFE6 (-0x1A)	Event failed? GOOL interpreter failed?
0xFFFFFFE7 (-0x19)	GOOL stack frame update unsuccessful.
0xFFFFFFE8 (-0x18)	Object linked list remove unsuccessful.
0xFFFFFFEA (-0x16)	Object could not be spawned from entity, pools are full.
0xFFFFFFEE (-0x12)	Chunk load failed.	Wrong magic, invalid page pointer, etc.
0xFFFFFFF0 (-0x10)	Unknown.	Returned by FUN_80012ed0 and FUN_80013084. Chunk load success?
0xFFFFFFF1 (-0xF)	Out of memory.
0xFFFFFFF2 (-0xE)	Object is malformed. Texture load success.	Returned on state change if object status b-flag 0x10000000 is set or if state is 255 (invalid), etc.
0xFFFFFFF6 (-0xA)	Tried to find null entry.	GetEntry was trying to find "NONE!".
