A title whose netplay mode draws every seat's view into one frame (so all peers keep identical guest state) can now ask the present path to show only this peer's rectangle of the display: psx_netplay_present_local_view(x, y, w, h), usually picked from psx_netplay_local_slot(). The GL dual-raster present shows it from the internal-resolution surface, the software present crops its staged frame, both at 4:3, and the headless present-image ring records the same rectangle. The request is host-only (never serialized or guest-visible), lapses PSX_NETPLAY_LOCAL_VIEW_HOLD ticks after its last renewal so menus fall back to the full frame, survives rollback replays without moving its stamp backwards, and is ignored offline. It wins over [netplay] local_viewport. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
