This proof of concept uses the initial piece order from [4853] NES Tetris "maximum score" by r57shell & Archanfel in 02:53.13 to check if the top line Tetris glitch was doable in the PAL version or not. Turns out it's in fact possible, though I didn't bother what the PAL speed limit for consistently doing this is here.
This was done to check something for #10238: NotMuch's NES Tetris "maximum score, PAL" in 00:51.773.
