Hi, I'm trying to port a game using PVR_PSP2, which loads GL functions dynamically but found eglGetProcAddress didn't return right address. The situation is:

init_pvr_psp2();
init_egl();
auto addr = reinterpret_cast<uint32_t>(eglGetProcAddress("glGetError"));
log("glGetError addr = %x, error = %x\n", addr, eglGetError());
// prints: glGetError addr = 0, error = 3000
log("glGetError = %d\n", glGetError());
// prints: glGetError = 0, might indicate that GLES module are loaded
addr = reinterpret_cast<uint32_t>(eglGetProcAddress("glGetError"));
log("glGetError addr = %x, error = %x\n", addr, eglGetError());
// prints: glGetError addr = 0, error = 3000

The complete test code can be found here. Additionally, loading libGLESv1_CM.suprx manually in init_pvr_psp2 would solve this problem. But I thought this might not be the correct way to use it. Anyway, thanks for developing this excellent repo! Any help will be appreciated.

Made adjustments to SGXGetRenderTargetMemSize

Moved some defines from psp2_pvr_defs.h and added some new defines to the relevant headers.

Renamed and added comments to psp2 specific fields of SGX_KICKTA_COMMON.

Tried to make this as close to how it was handled originally.

Added Core Functions for both GLES1.1 and GLES2.0 in their respective GetProcAddress functions. Enabled by EGL_CORE_FUNC.

API_MODULES_RUNTIME_CHECKED is now defined and functionality fixed, allowing EGL to check which graphics library is available at any given time by AppHint paths. This change is entirely internal and results in no changes for the developer.

Hi. When I try to use glsl to write a vertex shader. Everything runs well when I put the assignment of gl_Position in the first line of the main() function. But when I move it to the last line of the main() function, an error occurred in the vertex coordinates.

This is my repository: https://github.com/ZeroNinx/VitaTest

If you want to get a wrong result, just move the assignment of gl_Position to the last line of the main() function in data/Shader/VertexShader.glsl.

like this:

#version 100

attribute vec3 aPos; //顶点位置
attribute vec2 aTexCoord; //纹理坐标
attribute vec3 aNormal; //法向量

uniform mat4 ModelMat; //模型矩阵
uniform mat4 ViewMat; //相机矩阵
uniform mat4 ProjMat; //投影矩阵
uniform mat4 TranspostInverseModelMat; //模型矩阵左上角的逆矩阵的转矩阵（用于计算法向量）

varying vec3 FragPos; //片段位置
varying vec2 TexCoord; //纹理坐标
varying vec3 Normal; //法向量

void main()
{
   //Place it here is right
   // gl_Position = ProjMat * ViewMat * ModelMat * vec4(aPos, 1.0);

    TexCoord = aTexCoord;
    FragPos = vec3(ModelMat * vec4(aPos, 1.0));
    Normal = mat3(TranspostInverseModelMat) * aNormal;

   //Place here cause vertex coordinates error
   gl_Position = ProjMat * ViewMat * ModelMat * vec4(aPos, 1.0);
}
