Retiming for categories that kill Nightmare:

Time starts at the frame before the screen begins to fade white upon file select.

Time ends on the first frame the screen flashes orange upon hitting Nightmare.

Submitted times for these categories should be accurate to the second. More accurate timings are not required unless to break a tie for world record.

Retiming for credits warp (any%):

Time starts at the frame before the screen begins to fade white upon file select.

Time ends on the first frame the screen changes upon credits warp input.

Submitted times for these categories should be accurate to the millisecond. Submitted times will be edited by mods to reflect accuracy if needed.
