when implementing the

Code:

case CELL_GCM_TEXTURE_R5G6B5:
        {                                        
            glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, tex.GetWidth(), tex.GetHeight(), 0, GL_RGB, GL_UNSIGNED_SHORT_5_6_5, pixels);
            checkForGlError("GLTexture::Init() -> glTexImage2D");
            //glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_SWIZZLE_A, GL_ONE);
            break;
        }

it gaves me a very strange picutre
