NTSC Raster Positions
Good afternoon gents.
Is Rasterline #$00 to #$13 located in the lower border on NTSC machines when bit 7 of $d011 is cleared?
Tried to do a vsync (bit $d011 + bpl/bmi) and turned to debug borders and had to wait for rasterline #$14 before it was in the top border.
On PAL it works as expected though. |

Back when x64sc was written we asked for people to run test programs, often via IRC, and got loads of test data back. If there were surprising results (like the first encounters with PAL-N) we would do updated test programs and re-ask for testing. Most of these machines weren't in our direct possession. |
