Unknown function info

• The 22 Sony-specific exports in Export.cpp have names recovered by tools/nid_names.py from its pinned NID database. Each name hashes to the original explicit NID. Their prototypes and behavior remain unverified; all retain no-parameter throwing placeholders. No recovered name is a standard EGL or GLES2 function.

Additional callable exports

• Additional callable exports - 7 callable NIDs match the public 3.20 catalogue and the selected export metadata from two version-labelled images (SHA-256 5d1eb4913d2914be044c05a48c4287a3a73e526605f21ec37ce9acfb5b2170ad). The labels are not authenticated. Prototypes and behavior are unverified; these declarations throw through NotImplemented_nid_no_patch and implement no runtime functionality.

• scePigletSetConfigurationVSH (M9RtXpjSYtE) is listed in the same 3.20 catalogue and is declared as a no-parameter throwing placeholder; its prototype and behavior are unverified.

Additional unidentified exports

• Seven callable exports are declared as throwing placeholders. Their names, signatures and behavior are unverified. The same module and library identities occur in two version-labelled images; those labels are not authenticated.

Functional

• The host implementation is not a conformant GLES2 renderer. The single pbuffer configuration advertises EGL_NON_CONFORMANT_CONFIG and no EGL_CONFORMANT bits. Native window/pixmap integration, OpenVG client-buffer import, GLSL ES compilation, program linking/reflection and rasterization are absent. The 35 standard exports below still call NotImplemented_nid_no_patch; no shader or program can acquire a successful compile/link status. Uniform locations and storage require linked shader reflection and remain unavailable.

• State queries: glGetBooleanv, glGetFloatv and glGetIntegerv throw for GL_SHADER_COMPILER; compiler availability cannot be advertised until a compiler is integrated. Other implemented state queries use host limits, not measured console limits. Calls requiring a GL context throw when none is current; GLES2 does not specify that case.

• Console-specific ABI behavior and implementation-dependent limits are unmeasured. The host contracts come from EGL 1.4 sections 3.1-3.8 and OpenGL ES 2.0.25 sections 2.7-2.10, 3.7, 4 and 6. The backend has one default display, ES2 contexts, a single RGBA8/depth16/stencil8 pbuffer configuration, 2048-pixel image limits and eight vertex attributes and texture units. It supports no compressed texture formats, shader binary formats, EGL texture-binding configurations or extensions. Native-display handles other than the default do not resolve.

• Mipmap filtering uses a CPU box filter; implementation-dependent rounding and dithering have not been compared with console output. The state/storage implementation does not establish shader execution precision or rendering capabilities; glGetString and glGetShaderPrecisionFormat remain throwing exports.
