Hey guys. Quick question regarding PAL scanlines. There are 312 scanlines per frame. 70 of them are VBlank, 1 is Post Render, 1 is Pre Render, and 239 of them are the actual visible screen. If you do the math, it only equates to 311 scanlines. 239 + 70 + 1 + 1 = 311. What is the missing scanline? Been scratching my head on this. Thanks in advance.
