YglRenderFrameBufferShadow does not work???

devmiyax commented 1 year ago

Sprite window function use msb on the frame buffer. VDP1 draws msb with (CMDPMOD & 0x8000) or color CMDCOLR(bank mode). msb on CMDCOLR is cleared in Vdp1ReadPriority. I don't know why. But using this value sprite window function works.

back to main textgure.

        YglRenderFrameBufferShadow();
        glBindTexture(GL_TEXTURE_2D, YglTM->textureID_in[YglTM->current]);
        glBindBuffer(GL_PIXEL_UNPACK_BUFFER, 0);
