Congratulations nightmareci! From the looks of things, even after 999 lines you still could have carried on quite easily! You actually inspired me to give this another quick go today - things were looking real good until I topped out at about 550k

I stuck some of the run up on youtube (from level 15, up to near where I died), but it's a full 11 minutes, so it might be a bit boring for people not interested in SEGA Tetris: http://www.youtube.com/watch?v=O8I9dmolCeI

Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.

3. ### Edoa.k.a. FSY

Impressive Kitaru, keep it up!! I don't suppose you were recording were you? I'd be interested to see your playstyle in action.

4. ### Kitaru

I have an .inp I think, yeah. Maybe I'll link it, maybe I'll record. My play style is bad, probably, haha.

5. ### Edoa.k.a. FSY

It can't be that bad if you can survive to 500k!

Recorded: Part 1 and part 2.

EDIT: I copy-pasted my code tag there from my last post, and forgot to edit the date. Fixed now.

I didn't know there was a sega tetris leaderboard
Remember playing it on my megadrive on a pirate 180 in 1 HK cartidge when I was, like, 14
I will give it a go this evening but... the randomizer is soooooo cruel in this game lol

The game actually generates a 1000 piece looping sequence each time you start a game.

The pattern doesn't continue where you leave off, instead a new pattern is generated with a new seed.

However this sequence of seeds doesn't change either. So the second game has it's own "poweron pattern" the third game has it's own "poweron pattern", etc.

The number of possible seeds is not yet known. IF someone versed in assembly can reverse engineer the generator, then the size of the seed can be calculated, and the number of possible seeds worked out.

Notably, this has a few implications

1) to max out the line counter you must survive two loops of the pattern.
2) if you get a bravo on piece 1000, you can play forever.
3) even though it has a true memoryless randomizer, some, if not all, possible games of Sega Tetris may be foreverable. There may be 1000 piece sequences the game gives out that can't be survived indefinitely.
4) The poweron pattern ends with a I, and therefore may potentially allow a tetris bravo on the last piece.

1x Bravo (L triple) well after the score max-out. The max-out was in... 776 lines? 77x for sure.

10. ### nightmareci

It's not a new record for me, but it is a maxout, all in one video, since YouTube allows that now.

I've developed some new techniques to survive more consistently, but I've gotten somewhat rusty at Sega Tetris, so I sometimes make placements that would work in TGM.

Maybe I'll try to outdo my old record, but I've been mostly focused on TGM lately.

In anticipation for the newly announced M2 port...

Played on shmupmame 4.2 using "set 4" (tetris.zip) on hardest, no bravos
