Broadcast has a Default entry in the settings (value 4), but
fixUpDCFlash() only writes values in range, so Default left the flash
byte alone: NTSC from the factory block on a fresh flash, or whatever
the last explicit choice had written. A PAL game booted in NTSC with
Broadcast on Default.

Region's own Default is resolved from IP.BIN just above; resolve
Broadcast the same way: PAL for Europe, NTSC otherwise. Applied with
override() at load, like the region, so the saved setting stays Default.

Testing: compiles on macOS arm64.
