 ### Error Handling
 
-Instead of throwing exceptions, generally try to use
-[ox::Errors](deps/ox/ox-docs.md#error-handling) for error reporting,
-but exceptions may be used where they make sense.
+The GBA build has exceptions disabled.
+Instead of throwing exceptions, all engine code should return
+[ox::Errors](deps/ox/ox-docs.md#error-handling) for error reporting.
+For the sake of consistency, try to stick to ```ox::Error``` in non-engine code
+as well, but non-engine code is free to use exceptions when they make sense.
 
 Exceptions should generally just use ```OxException```, which is bascially an
 exception form of ```ox::Error```.
