• I am using an official build obtained from releases or updated one of those builds using its in-app updater.

Describe the Bug

The Witch and the Hundred Knight: Revival Edition (CUSA02799) suffers from an unhandled shader translation field and an uninitialized structure bug in the HLE audio engine (libSceNgs2), resulting in a fatal 0xc0000005 access violation.

When both are patched locally via stubs, the game successfully passes the loading splash screen, shifts play state, and renders the main menu layout seamlessly. However, it completely softlocks upon hitting "New Game" or "Load Game" due to an infinite loop waiting on sceNgs2VoiceGetState updates.

Reproduction Steps

1. Launch CUSA02799 on default master branch builds.
2. Observe immediate compiler failure/crash regarding missing GetLdsDirect implementation inside Shader::IR::IREmitter (encountered enum operand value 254).
3. If bypassed by stubbing OperandField::LdsDirect in translate.cpp with a zero immediate value, the game boots further but immediately drops a fatal 0xc0000005 Access Violation at address 0x800c93d99.
4. This memory fault is traced to sceNgs2ParseWaveformData in ngs2.cpp, which exits leaving OrbisNgs2WaveformInfo* outInfo entirely uninitialized.

Expected Behavior

The shader recompiler should safely process or gracefully stub LdsDirect operands, and libSceNgs2 should safely initialize memory outputs (or return appropriate error states) to prevent the game's core execution thread from encountering random uninitialized memory structures.

Furthermore, sceNgs2VoiceGetState requires proper cycle/playback flag transitions to allow games reliant on NIS engines to pass initialization locks and advance into 3D world levels.

UPDATE: Game advances past audio block to Loading Screen!

Upon further testing after hitting "New Game", the engine actually bypassed the audio loop lock and began loading level assets! It successfully rendered a loading screen with game tips and began compiling multiple Vulkan pipelines before ultimately triggering a critical GPU assertion crash:

liverpool_to_vk.cpp:777 SurfaceFormat: Assertion Failed! Unknown data_format=21 and num_format=7

This proves that the std::memset audio workaround successfully satisfies the engine's state requirements to transition into active gameplay asset loading, shifting the current hard roadblock to a missing texture format mapping (data_format=21, num_format=7) inside the GpuCommandProcessor.
