Monochromatic blue tetris using row 20 glitch

To my knowledge nobody's done this before as a TAS, let alone RTA like this is. I messed up the holdout a little bit but got bailed with 3 straight specific pieces I needed at the end. This setup isn't that consistent since it obviously needs J/S spam, plus the double longbar skim at the top, but it's better than I expected to find (I'd say it's probably close to the optimal setup), and I got lucky enough to get it after only one attempt that failed at the last piece.
Technically the bottom row, which gets glitch cleared due to row 20 being filled, isn't all blue. Maybe something I'd someday go for, but right now I'm perfectly satisfied with every filled row being all the same color :)

The bottom row is not fully blue- but this is genuinely impressive!

[@triskai]

thx! I did mention that in the description

[@wiirambo7437]

@@triskai Interestingly the bottom row is not cleared it is shifted one row down and no longer visible, but it is still in RAM. The top 3 row are actually cleared and the row one above the screen is shifted to the player 2 board; effectivly clearing it.

I don’t get it

It cleared the bottom row of blocks (which wasn't a completely filled row) at the same time as when the top 4 rows got cleared. Hope that makes sense.

[@biggiemac42]

when you clear the topmost line of blocks in nes tetris it counts twice, because of the way that the loop in code works to check cleared lines. Doing this will shift the whole playfield down by one, it's really funky looking but not completely unusual (people who cleared checkerboard height 8 use it pretty much every time). One consequence of this is that you can score a tetris using a J or L piece in the top row.
What triskai did here is strategize a way to build the 3 top rows out using completely blue pieces to score a "monochromatic tetris", aka all lines cleared are the same color the whole way left to right. Usually to get a monochromatic tetris you need the color to be white because the bar is the final piece and it's white. But with top row glitch then the piece can be J and the color can be blue.
She did this in a real game and not a tas, which is insane. She found a way to stash pieces that weren't useful in the center of the playfield without running out of space or clearing lines which would bring the top row down and ruin the glitch, and she got the perfect final couple of pieces to get it done.
