# libSceHmd technical debt

### Silent stubs

- [libSceHmd](../../../core/libs/prx/libSceHmd/Export.cpp) implements only the disconnected-headset path: initialization succeeds, device queries report `NotDetected`, and opening a device returns `DeviceDisconnected`. Headset support, tracking, rendering and additional HMD exports are not implemented; SDK-level ABI compatibility and in-game behaviour remain unverified.
