The best TI-83+ Tetris ported to KnightOS.
Original by Jimmy Mårdell yarin@acc.umu.se, Sam Heald evil_sam@hotmail.com, and Patrick Davidson eeulplek@hotmail.com.
ION and Ti-83/+ Version by Ahmed El-Helw ahmed@ticalc.org
First, install the KnightOS SDK. You will also need the new scas assembler. Sass will not work.
$ knightos init --assembler=scas
$ make
$ make run # to test
$ make package # to produce an installable package
Use make package to get a package that you can install.
If you need help with KnightOS, want to keep up with progress, chat with developers, or ask any other questions about KnightOS, you can hang out in the IRC channel: #knightos on irc.freenode.net.
To report bugs, please create a GitHub issue or contact us on IRC.

-
21 levels (0-20). You can choose which level to start between (only start on level 0-9 though).
-
16 different level patterns!
-
Hiscore table with names! The three best results are saved.
-
Teacher key! If you see your techer heading your way, quickly press the teacher key to return to TI-OS, and when you start the game the next time, you'll automatically resume where you was. If you run it from a shell however, it returns to the shell instead. But that's your problem, not mine :)
-
Linkplay! Play against each other and kick some butt! The link protocol is the same as in ZTetris for the 86 and Tetris for Fargo, so you could link an 82 to an 85, 86, or a 92 and play against each other!
-
The scoring is almost the same from the Game Boy version. The last digit in the score isn't shown (you could think of it that way anyway) because of several reasons. Unlike the ZShell version, you also score for dropping or moving down a piece.
-
You can start with trashlines. It's different from the gameboy version though, because there is no win-when-cleared-25-lines.
-
In linkplay, you can choose if you want to get scrambled (as in Tetris for Windows) or unscrambled (Tetris for Gameboy) lines.
-
Rotation in both direction. You can pause the game (1 player)
Choosing players: Up/Down - Change number of players
Mode - Quit
At the option menu: Arrowkeys - Choose level
Enter/2nd - Start level
S - Toggle "2-4 lines", "1-3 lines" (LP only)
L - Toggle scrambled/unscrambled lines (LP)
Minus - Decrease start high
Plus - Increase start high
Mode - Quit game
When playing: Left & Right - Move the piece to the left and right
Up & 2nd - Rotate clockwise
Down - Move the piece faster down
xto - Drop key
Alpha - Rotate anti-clockwise
Clear - Quit game
Mode - Pause
Del - Teacher key. Quickly pauses the game and
jumps out to the Castle.
| L 0 | L 1 | L 2 | L 3 | L 4 | L 5 | L 6 | L 7 | L 8 | L 9 | |
|---|---|---|---|---|---|---|---|---|---|---|
| 1 line | 4 | 8 | 12 | 16 | 20 | 24 | 28 | 32 | 36 | 40 |
| 2 lines | 10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 | 90 | 100 |
| 3 lines | 30 | 60 | 90 | 120 | 150 | 180 | 210 | 240 | 270 | 300 |
| 4 lines | 120 | 240 | 360 | 480 | 600 | 720 | 840 | 960 | 1080 | 1200 |
When dropping a piece, your score will increase with dropsteps/10 (the last digit will remain in memory, although not shown). Every time you move the piece down (with the down key) you will increase the score with 0.1.
To play linkplay, first connect two TI-83's (or connect the TI-83 to a TI-82, TI-85, TI-86, or a TI-92) and choose two player mode. The level selection menu looks slightly different. Besides from choosing which level to start at (the two players can start at different levels), you can choose how many penalty lines should be sent to the other calc when clearing lines. Either you send 2-4 lines (if you get 2-4 lines) or 1-3, ie one line less than you cleared. This option can also be different on both calcs, thus allowing handicap. You can also toggle if you want to get unscrambled penalty lines or scrambled penalty lines. If choosing unscramble (defualt), the lines sent to you will only have one gap, making it much easier than getting totally scrambled lines.
Press Enter to start the game. Now the calc will go into waiting mode and wait until the other player has reached this mode. When one player enters the waiting mode, the other player MUST have started ZTetris (or be in an assembly shell) because else the game would start immediately for the first player. If you link with a TI-82 or a TI-85 or a TI-86 or a TI-92, the other calc must enter Waiting mode first.
Now the fun begins!
You play as you usually do, but when you clear 2 or more lines, the other opponent will get penalty lines depening on how many lines you cleared and the option choosed when selecting startlevel.
There is also a bar telling how high up in the playing field your opponent is (it's not visible in the beginning since the field is empty). This is good when choosing strategy.
When a player loses, or aborts the game, a "You won" message will appear on the other calc.
You can't pause or use the teacher key in two player mode, and you can neither enter the hiscore table (even though score is counted)
When you play against an 85/86 know that the 82 version runs slightly faster than those versions. Set the 85/86, one level higher than the 82 to even things out.
- Don't pull out the linkcable while playing twoplayer! The calcs may freeze a few seconds (not crash).
- The linkplay probably isn't that stable, and the calc may freeze sometimes for a short time. It is also possible that one player may "miss" some penalty lines :) See this as a feature instead hehe :)
