forked from Ports/goldeneye-pc-port
First behavioral src/ hook under the AGENTS.md #2 documented-exception path. src/fr.c viShake() gets one #ifdef PORT line multiplying the incoming amplitude by portScreenShakeScale (extern f32, registered 0.0-10.0 in port/src/video.c, committed with WI-1). Default 1.0f is an exact no-op so headless golden dumps are byte-unaffected; 0.0 disables explosion/effect screen shake. N64 build keeps the original line under #else. findings D180/D181 + F-index.
