- [NGS2 custom Delay](../../../core/libs/prx/libSceNgs2.native/src/Custom.cpp) (libSceNgs2.native, 0x1d) - processing and defaults remain unverified on PS5. The [agreed compatibility path](https://github.com/boykopovar/AnyPS5/pull/9337#issuecomment-6351205140) preserves main's PCM pass-through for Void Terrarium (PPSA03061) until any Delay parameter is set; every `0x40001dxx` parameter throws. Only one-buffer custom submixers with no module state and a 20-byte option are accepted. Option type 0/1, taps 1..8, length 1..20000 and reserved 0 follow [fma-rc's 12.70 module reading](https://github.com/boykopovar/AnyPS5/issues/8039#issuecomment-6319332943). Other shapes and values throw because their console errors are unknown. This preserves host behavior, not console-equivalent Delay processing
- [NGS2 custom module ids](../../../core/libs/prx/libSceNgs2.native/src/Custom.cpp) (libSceNgs2.native) - Reverb (0x1b) and Convolution (0x23) are not processed: a rack that passes their creation checks throws. Gain (0x15) on custom sampler racks also throws. Per [fma-rc's 12.70 module reading](https://github.com/boykopovar/AnyPS5/issues/8039#issuecomment-6294323150), creation returns `0x804A8302` for a wrong non-zero state size, and `0x804A8013`, `0x804A8099` and `0x804A8098` for a bad Reverb option size or word and PitchShift word. Unknown: check order, errors for a Gain option, missing Reverb options, Convolution option sizes, and Convolution's state (64 bytes from SDK 3.0). PPSA04540 uses 0x15, 0x19, 0x1b and 0x23 (#8039), PPSA35169 0x20 (#4246) and PPSA33655 0x15, 0x19 and 0x1b
- [NGS2 custom PitchShift](../../../core/libs/prx/libSceNgs2.native/src/PitchShift.cpp) (module 0x20) accepts absent options or an 8-byte option with quality 0, and processes custom submixer racks in 64-sample blocks, with cents clamped to -1200 through 1200, channel bypass, input filtering, waveform-aligned overlap and resampling. Default and setup-reset parameters bypass the module. Buffered processing continues while paused; pause, resume and stop use 64-sample output fades, and playback restart clears the history. PCM and buffer-state comparisons cover impulses, tones, noise, silence, parameter changes, reset, module indices and independent voices. The reconstructed resampling kernel produces float-rounding differences; sampled comparisons stayed below 1e-6 for input magnitudes up to 0.5. Active processing requires a grain divisible by 64. Pitch-down inputs with no selectable overlap throw instead of stalling. A channel bypassed at initialization cannot be enabled until a playback restart: this throws instead of reproducing the reference's non-terminating filter loop. Custom sampler racks with PitchShift still throw; their upstream sampler resampling path has an unmodeled three-sample startup delay, which changes the effect's waveform alignment. The title stop in [PPSA35169](https://github.com/boykopovar/AnyPS5/issues/4246) uses a custom submixer; no title run has verified progress past it.
- [NGS2 custom PitchShift](../../../core/libs/prx/libSceNgs2.native/src/PitchShift.cpp) (module 0x20) - active processing requires grains divisible by 64. Pitch-down inputs with no selectable overlap throw instead of stalling. A channel bypassed at initialization cannot be enabled until playback restart: this throws instead of reproducing a non-terminating filter loop. Custom sampler and submixer paths support cents -1200..1200, bypass, filtering, waveform alignment and resampling; setup defaults to bypass. Pause/resume/stop fade over 64 samples and restart clears history. Sampled PCM comparisons stayed below 1e-6 and ATRAC9 below 5e-6. The shared sampler uses Q14 phase, four history samples and a 512-phase kernel, producing three initial zero samples at unity rate. No title run has verified progress past the [PPSA35169 stop](https://github.com/boykopovar/AnyPS5/issues/4246).
- [NGS2 sampler replay and replacement](../../../core/libs/prx/libSceNgs2.native/src/Sampler.cpp) - playback restart retains waveform descriptors up to the rack's configured block capacity (at least one); exceeding that retention budget makes the next PLAY throw; already-running playback continues. Streaming pieces have the same retention bound. Active ATRAC9 waveform replacement preserves the decoder for the same data descriptor; replacing it with different data or lengths throws because the decoder's cached superframe replacement behavior is unmodeled. Nonzero sampler setup channel masks and transitions on grains below 64 throw. Callback-driven setup/reset still stops the current reader at its revision boundary; exact reference timing for callback replacement and partial compressed input remains unverified. The custom sampler state layout and size validation still have the limitations listed below.
- [NGS2 custom Gain module](../../../core/libs/prx/libSceNgs2.native/src/Custom.cpp) (libSceNgs2.native, rack 0x4002) - follows [fma-rc's reading of the 12.70 module](https://github.com/boykopovar/AnyPS5/issues/8039#issuecomment-6319332943): parameter `0x40001500 | module index` holds 37 linear levels, one per channel, default 0, and the module writes source × level into dest, ramping linearly over the grain from the previous level. Unverified: where the ramp starts and ends (here the grain's first sample is one step past the previous level and its last sample is at the new level), whether stopping or setting up the voice again resets the levels, and what the library does with a level outside -32 to 32 (here it throws). On a custom sampler rack, whose parameter index is one higher per fma-rc, Gain throws. A Gain module with an option throws: fma-rc reads Gain as taking none, and the error the library returns for one is unknown. The extra buffer is ignored, as fma-rc reads it
- [NGS2 custom mastering rack](../../../core/libs/prx/libSceNgs2.native/src/Rack.cpp) (libSceNgs2.native, rack 0x4003) - follows [fma-rc's reading of the 12.70 module](https://github.com/boykopovar/AnyPS5/issues/8039#issuecomment-6319332943): option size is 0x508, matching the custom submixer rack layout. Creation returns `0x804A8052` above 37 channels; channels 9 to 37 throw because voices hold at most 8 channels. Mastering racks with modules throw: attached modules and non-default option fields are unverified on PS5. Voice control parameters 0x40030000 (setup), 0x40030004 (gain) and 0x40030005 (output) configure channels, levels and destination buffer. `sceNgs2VoiceGetState` fills common voice state flags. PPSA10278 and PPSA04540 create rack 0x4003 without modules (#8039)
