Adds two selectable Forecast Channel weather modes:
- On by default: hold B before the title screen to disable weather for the session.
- Off by default: hold B before the title screen to enable weather for the session.
Both modes support Wii Remote and Classic Controller B on all 11 supported revisions. The patcher retains ID4 mod matching and existing patch-site checks.
Validation: host weather and loader tests, patch injection tests for all revisions, and 198 checks of the bundled PowerPC code.
