I don't think it would be quite pre-render. Aren't games able to access the PPU memory during all parts of vblank? If it were 51 lines of pre-render, this would be impossible due to the PPU's fetches for the BG.tepples wrote:So it might not be 70 lines of vblank and 1 line of pre-render as much as 20 lines of vblank and 51 lines of pre-render. Does this newly discovered OAM copy failure also happen if you have forced blank on?
