 ## Description
 
-TBD
+Runs an emulator instance until a [[vblank callback|GB_set_vblank_callback]] is called. Returns the number of time passed, in units of 8MHz (8,388,608Hz) ticks. Unlike [[GB_run]], this function does not handle time keeping, and will not sleep.
 
 ## Thread Safety
 
 `GB_run_frame` must not be called if the instance is being run in any thread, including the current one (via a callback).
