TETRICS v.2.0 readme file 
                   (C) Copyright 1994 Serge N. Fokin 
  
TETRICS is a tetris game. It combines the classical 4-square tetris 
with (more interesting) 5-, 6-square and MIX variants. There is quite 
some number of Tetris games on the net; however none of these (at least 
none of those I found) offers those advanced variants. 

TETRICS is distributed as shareware. That means that you are free to use 
it for a 10 days evaluation period; after that, if you continue to use 
TETRICS, you are expected to register. You will then receive registered 
version (with colored pieces option and a few other extras). 

Currently VGA, SVGA, EGA, CGA, Hercules and several other graphic 
adaptors are supported. 

TETRICS has a built-in screensaver (You can disable it if you prefer 
some other screensaver or none at all). 

This is the DOS version of TETRICS. Windows version is in the works and 
probably will be ready by late summer-1994. Check your favorite 
FTP-site.

1. To install, create a directory (for example C:\TETRICS or 
   D:\IMPORTNT\BUSINESS or smth) and copy all the files in this package 
   into it. After that, 

                       A. If you are not familiar with batch files and 
                          have no intention to become familiar with them 
                          - just run TETRICS from that directory 
                                                                 or 
                       B. Edit the included TTR.BAT by typing in the 
                          name of directory you created and place it 
                          (TTR.BAT) into the root directory or some 
                          directory which is in your search PATH - this 
                          way TETRICS can be run from anywhere. 

   Notice that TETRICS looks for configuration file and records table in 
   the current directory; so there is some point in running it from the 
   same directory each time. Three hurrahs to batch files. 

   If you use graphics adaptor other than EGA, VGA or SVGA, it's 
   necessary to specify it on the command line, i.e. 

   TETRICS /CGA    for CGA adaptor 
   TETRICS /HGA    for Hercules adaptor 
   TETRICS /O      for adaptor other than VGA, SVGA, EGA, CGA or 
                   Hercules (supports some older AT&T and Olivetti 
                   computers) 

   If you use EGA, VGA or SVGA adaptor with a monochrome display, try 
   running TETRICS either with or without /MONOVGA option. Both variants 
   should work, choose whichever looks better on your system. 
  
  

2. Blocks fall from the sky. You can move them right and left, rotate 
   them, and, if invertkey is ON, invert them. When a full row is 
   formed, it disappears. Aim is to get as many rows as possible and/or 
   as high score as possible. 

   List of keys: 

     During the game: 

        Left-arrow or 4                 Moves left 
        Right-arrow or 6                Moves right 
        Up-arrow or 8 or 5              Rotates 
        Home or 7                       Inverts 
        Down-arrow or 2 or Space        Drops fast 
        ESC                             Quits to DOS 
        - (minus sign)                  Pauses game 
        T                               Toggles grid on/off 

     On the "set options" screen: 

       Arrow-keys                       Move between windows 
       Enter                            Acts on the current window 
                                          (Changes the displayed value 
                                          or calls new screen) 
       ESC                              Quits to DOS 
       Space                            Starts game 

   List of options: 

        Game - can be 4, 5, 6 or MIX 
        Mixtoughness - from 1 to 5, matters only if MIX is the current 
                       game 
        Speed - from 1 to 10 
        Invert key ON/OFF - when it's ON, you can invert figures. 
                            There's quite some penalty in score, though. 
        Records Table by Score/Rows - the table of greatest hits is kept 
                        according to either scores or rows. 
        Screensaver OFF/blanker/stars - chooses whether screensaver is 
                        on and if yes then what is it's style. 
        Delay time - time without a keypress after which screensaver (if 
                        it's not OFF) is activated. 

     Registered version only: 

        Colors ON/OFF - with colors OFF, all pieces are green. With 
                        colors ON they are different colors. Looks 
                        really nice. 
        Keyboard customization - keyboard customization. 

   Hints:   - When figure drops onto something, it still can be moved 
            for a short time. 

            - 5 with invert key OFF 
                         and 
            - MIX with invertkey ON, mixtoughness 3, 4 or 5 

            are said to be the most interesting games. 
            A newcomer might start with 4, though. 

   Scores:  Score is proportional to speed and difficulty of the game. 
            If invertkey is ON and it's used at least once during a 
            game, then score is divided by 5. 
  
  

3. To register, send check for US$ 10 drawn on an U.S. bank or US$ 10 (or 
   equivalent in other currency) in cash to (if you send cash, do wrap it 
   into some paper so that it will get through.. Thanks!): 

                     Serge Fokin 
                     P.O.Box 906 
                     Rochester, NY, 14603 
                     U.S.A. 

   You can print out and enclose the TTRORDER.FRM file or just mention 
   your system type (IBM-PC, Mac, etc.) and diskette size (5 or 3 
   inches). I will send you a diskette with newest release of TETRICS 
   registered version. 

   If you do not really care for registered version (colored pieces, 
   keyboard customization.. Are you sure?   #:-)    ), send just $ 8 for 
   registration itself. 

   I can also be reached by e-mail at lckh@troi.cc.rochester.edu. Bug 
   reports & comments are welcome. Notice that even if that e-mail 
   address will change some day, I intend to maintain the P.O.Box - 
   so it still will be possible to reach me by usual mail. Anyway, if 
   your copy of TETRICS is fairly old and the e-mail bounces you might 
   check some FTP site for newer version of the game.. 
  
  

4. Customization & troubleshooting. 
  

   Customization: 

   /S option. Normally when TETRICS is run it shows the "set options" 
   screen. If the /S option is specified it goes directly to start of 
   the game with the current default settings. Nothing else is changed. 
   You still can get to the set options screen by pressing  after 
   end of a game. (Default settings are stored in the INI file and 
   updated each time when you modify options). 
  

   Advanced customization: 

   /FF0 and /FF1 options. 
   There are two algorithms to display fastdropped figure in TETRICS. 
   Algorithm 0 is very smooth but too slow on slow machines. Algorithm 1 
   is rough and quick. TETRICS chooses 0 or 1 depending on the speed of 
   your machine; however for mid-range machines (fast 386's and slow 
   486's) it is really question of taste. You can force algorithm 0 or 1 
   respectively by specifying /FF0 or /FF1 option. 

   /RF option. 
   When a figure is fastdropped (with Space or Down-arrow or 2 key) 
   player normally loses control of it. If the /RF (ReversibleFastdown) 
   option is specified, that is changed: if a figure is fastdropped and 
   then any key is pressed before it have hit the ground, it slows 
   down to normal speed & all direction keys work again. Pro & cons: 
   With (default) irreversible fastdrop one can fastdrop a figure and 
   start pressing keys that will control the next one. Reversible 
   fastdrop is mainly good for situations when one needs to move figure 
   in the last moment and does not want to wait while it crawls down 
   with the usual speed. 
  

   Files in the package 

   Normally, the following files comprise TETRICS package: 
   TETRICS.EXE  TTR.BAT  README.TTR  and  TTRORDER.FRM 
   Please distribute these files only together, as a complete package. 
   Files TTR.INI and TTR_HITS.DAT are automatically generated during 
   normal operation. 
  

   Troubleshooting: 

   MS-Windows. 
   TETRICS is primarily a DOS application. On most systems it will not 
   work properly under Windows. Solution is to exit Windows and run 
   TETRICS from DOS or get the Windows-version of TETRICS. It is 
   currently in the works and probably will be finished sometime around 
   late summer 1994. Check your favorite FTP-site. 

   Write-protect or disk full errors. 
   TETRICS writes record hits file and INI file on disk. If disk is 
   write-protected or full, it will generate an error message. You can 
   remove write-protection or free up some space on disk; however if 
   it's not done, it's still OK to run TETRICS as long as you do not 
   mind error messages. 

   Corrupt files. 
   If (because of whatever reason) files TTR.INI and TTR_HITS.DAT become 
   corrupt that might cause TETRICS to behave strangely (because of 
   strange things it found in those files) or even crash. If that 
   happens, remove TTR.INI and TTR_HITS.DAT, TETRICS will automatically 
   generate new ones. 

   Running from the same directory. 
   TETRICS looks for TTR.INI and TTR_HITS.DAT files in the current 
   directory. If it does not find these files it will generate new ones; 
   It's not an error; however there is some point in using the same set 
   of INI & DAT files, right? So TETRICS is supposed to be run from the 
   same directory - the simplest way to achieve that is to run it using 
   the TTR.BAT file. Less typing, too. 

   Runs abnormally slow. 
   If that happens on a newer machine (386+) then it's the (very 
   unlikely) situation of a conflict with some other program - try 
   unloading TSR's (programs resident in memory); if you run TETRICS 
   from some operating environment other than DOS (Windows, Deskview) 
   try quitting that environment. 
   If the machine is an XT or a very slow 286, then it can be a problem 
   of the processor speed. If you tried unloading TSR's, etc and 
   that did not help, try running TETRICS in CGA mode (TETRICS /CGA). It 
   is a (comparatively) low resolution mode and on a slow machine it 
   will run faster. 

   NumLock key. 
   Normally TETRICS sets the NumLock key on during the game (and 
   restores it's status upon exit). If you do not want it do that, you 
   can add the /NONUM switch to the command line (TETRICS /NONUM). 
   Notice that if NumLock is off then <5> (on numeric keypad) key no 
   longer works for rotating a figure; all other keys work as usual. 

   /B0 option 
   Depending on the exact kind of the graphics adaptor TETRICS use one 
   of two different algorithms of dealing with screen blanking. If you 
   experience any problems with the screensaver, try /B0 option (it will 
   force algorithm 0 on a system where normally algorithm 1 would be 
   used). 
  
  

5. Acknowledgement: I understand that the original idea of TETRIS game 
   belongs to Alexei Pazhitnov and Vadim Gerasimov. Copyright on this 
   software is claimed on this particular implementation of the game.

   the author be liable for any damages resulting from use or misuse of 
   this software. 

   Anyone is free to distribute TETRICS as long as no more than a nominal 
   fee is charged in the process and files TETRICS.EXE, TTR.BAT, README.TTR 
   and TTRORDER.FRM are distributed together and not changed in any way 
   (other than being stored by an archiver program). 

   Everyone is free to use this program for 10 days evaluation period. 
   After that, you are expected to register or stop using it.
