frayien its because in nes version, when you are close to the top, it will clear an extra line, but since its already a tetris, it clears a “pentris” (5 lines) so then it doesn’t recognize that so it bugs and makes a full line
*gamefreak* In that case, it's not an A press. Half A Presses refer to when you use an A press after its initial use by holding it down. This technically isn't pressing it, but it still functions as an A press (Which is why it's called a half A press). But if it has to be one or the other, then it technically is not an A press.

This reminds me of a similar TAS video by Brandon Evans. His bot performed the same glitches as in this video, however... When his bot clears the lines at the top of the screen, the spawned line has its sixth block missing. Later in the run, the matrix fills up with (incomplete) lines just like this video, and because of the open column, his bot make one last Tetris setup before cheat the next queue in favour of the I-piece leading to five consecutive Tetrises. Was his video inspiration for the creation of yours, and how did you spawn complete *unclearable* into the matrix?
Not exactly. Lemme explain. The main glitch is that if you clear row 20 (top of the field), it also clears row 1 (bottom of the field). Now what the guy is doing in your video is build for tetrises with L/J, but since that requires to be at a certain height, the runner keeps readjusting while making a center well to score "regular" tetrises when its well reaches the bottom. Now this game was never meant to handle quintuple line clears. However with this glitch, clearing 4 lines at the top also clears the bottom one, you end up clearing 5 liens at once, confusing the game which decides to leave a full line on the screen. Those lines can actually be cleared by placing a piece flat on top of it, but instead of doing that, i just decided to put as much as i could on the screen at once. This is what actually inspired me: ua-cam.com/video/QQvVjC3xr4M/v-deo.htmlm34s
@@jongyon7192p you have to manipulate RNG perfectly for it to work though-and hypertapping is essential (level 16+ with anything close to the top is pretty much game over for any human player)-so it's pretty much TAS-only
True, though this works only on NES Tetris (iirc GB Tetris reacts differently to this), so our colour scheme is pretty limited, since we basically have to choose between 9 sets of 3 colours. Even if we _could_ access more palettes on levels 30+, those levels have a gravity of 1G (the pieces fall 1 row per frame), so creating an image under those conditions or even surviving with the image already done becomes a ton more complicated. Though if you meant patters like secret grade, checker board, etc., I assume any pattern is possible as long as it doesn't have a completely empty row. Getting the full line within the upper 4 lines of the field is also impossible (unless the top 2 ones but that requires dying in the process. tl;dr ok but dude thats hard
You stated that it tries to clear 5 lines for some reason. If that's the case, this is what I think happens: The game COULD do a quintuple line clear if all of the lines were adjacent to each other; however, one line is quite far away from the rest. So what happens is this: The game makes the top 4 lines, and the bottom-most line as 'cleared' The game moves the entire field down 1 row to fill in the bottom line Then removes the top 4 lines; but this leaves an extra full line leftover because they've shifted down one
If that were the case I'm pretty sure everytime you clear the highest row you'd have a leftover line. This happens only when you perform a Tetris. When you perform a triple on the top row, the game actually counts it as a Tetris, so it's literally trying to clear one more line when the top row is cleared. Since we're talking about a NES game, I wouldn't be surprised if the game was coded _specifically_ to handle 0, 1, 2, 3, or 4 lines, since that's the only thing it will ever have to deal with normally anyway. The "leftover" glitch is a side effect of the "top row counts twice" glitch: if the latter didn't exist, this video wouldn't exist either.
Same to be honest, but judging how the extra row it clears is under the field, I assume it's an over/underflow problem, could be completely wrong though. My other guess is that somehow the data there lines up and makes some other data detected as a line in the field by the game. When doing this TAS, was randomely blocked on the first off-screen row, despite me not putting anything there, so it could be more data translating to another row being cleared or something.
The game checks only within a small box around the piece for optimisation purposes. You can clear the filled lines by placing a piece flat side down on top of it.
Clearing row 20 for some reason also makes a row under the field count, so it counts for 2. Maxout TASes use that to trick the game into awarding a Tetris when completing only 3 lines, but I use it here as a way to confuse the game into thinking 5 lines are cleared. The game was only made to deal with up to 4 lines at a time, so the 5th one stays behind on every clear.
The game/programmer has no reason to check lines you didn't place a block on, so it seems reasonable that if you exploit a bug to fill out a line, it never gets cleared.
Apologies for the late reply, but yeah it's basically an optimisation to make the game check for lines a bit easier. It works on a bounding box though instead of just considering the current piece and it's orientation, so if you place for example a T piece flat on top of a solid line, the game will check the solid line under the T piece and clear it. You'll notice that I never do that in the video because that goes against my goal here. On modern games though if you were to make a full line not disappear for a bit it will probably get cleared next piece drop, since computers are way faster now and checking only part of the field isn't the kind of optimisation that really matters anymore.
So basically it's a glitch where when you get a Tetris the whole board is moved down by one block and the last row of the Tetris is kept, however this line is not cleared because the game does not support pentrises
This is basically heavy glitch abuse. When you clear the row at the top of the screen, the game also registers a line cleared below the screen, making the top row essentially counts double. That glitch is mostly used in TAS to make tetrises with L and J pieces. It saves like 2 or 3 pieces per tetris, so it's faster. Here though I clear 3 lines + the two from the top row, so 5 lines each time. Since this is unintented and the game was never meant to deal with 5 line clears, it clears only up to 4 lines, one of them being the row below the field. This means one of the rows will not be cleared and will stay on the screen. Placing a piece flat on top of it will update the area with the full line and clear it though, so it's not stuck forever. tl;dr glitch makes top row count for 2 making 5-line clears a thing but the game only clears 4
TASers do collabs all the time. The tasvideos.org forums are a common place for people to pool their knowledge on the various games and emulators. Some of the most optimized TASes have 15+ authors credited in their submissions and publications.
The RNG uses a sort of global timer to calculate what next piece you get on the fly. That way I can delay a lock by one frame and get a different piece if I want/need to
Oh, sorry. Well in that case here, it's pretty much I lock my piece, and if the piece I see in the next box is not the one I want, I rerecord and lock one frame later to change what's coming up. That's a little thing that helps in most cases when RNG isn't seeded and relies on timers. In the specific case of NES Tetris though, since the game tries not to deal the same piece as the previous one, you can change your strategy so that you don't have to manipulate luck as much. For example, if you're looking for OTII but it's still possible to do what you want with OITI or IOTI, you may want to go for those instead. Then again, I assume testing both arrangements would not hurt since you never know if you actually don't need to manipulate luck.

The game COULD do a quintuple line clear if all of the lines were adjacent to each other; however, one line is quite far away from the rest.
So what happens is this:
The game makes the top 4 lines, and the bottom-most line as 'cleared'
The game moves the entire field down 1 row to fill in the bottom line
Then removes the top 4 lines; but this leaves an extra full line leftover because they've shifted down one

Since we're talking about a NES game, I wouldn't be surprised if the game was coded _specifically_ to handle 0, 1, 2, 3, or 4 lines, since that's the only thing it will ever have to deal with normally anyway. The "leftover" glitch is a side effect of the "top row counts twice" glitch: if the latter didn't exist, this video wouldn't exist either.
I wonder what causes the top row to be counted twice in such a case then.
Same to be honest, but judging how the extra row it clears is under the field, I assume it's an over/underflow problem, could be completely wrong though.

The fact that every line is covered, but not cleared is so funny
Is that loss
This is like it looks like it lowers but in reality it’s at the same level
1:48 Why didn’t all the bottom lines clear?
The game checks only within a small box around the piece for optimisation purposes. You can clear the filled lines by placing a piece flat side down on top of it.
Even the TAS bot was confused

So I guess NES Tetris wasn't coded to accept full lines on the top row but that's only the start of the issues.
WHY WERE FULL LINES NOT COMPLETING I DON’T TGINK A TAS DOES THAT

how is he able to choose what pieces come next? he gets the long bar exactly when he needs it. is he manupulating the random number generator?

How does one manipulate luck?
The RNG uses a sort of global timer to calculate what next piece you get on the fly. That way I can delay a lock by one frame and get a different piece if I want/need to
Lilla Oshisaure thanks for explaining! I want to try it out in TAS, is there a tutorial?
I didn't use a tutorial personally, but bizhawk or FCEUX both have a pretty intuitive TAS editor
Lilla Oshisaure I know about tases, I’ve done them myself before. I just want a tutorial on luck manipulation
Oh, sorry. Well in that case here, it's pretty much I lock my piece, and if the piece I see in the next box is not the one I want, I rerecord and lock one frame later to change what's coming up. That's a little thing that helps in most cases when RNG isn't seeded and relies on timers.
