Changes:

• added support for the pre-ANSI VT52 terminal.
• optimized terminal redraw, major improvement in playability and responsiveness at low baud rates, now playable down to 2400 baud.
• move the cursor out of the way on vt100 which doesn't support hiding it.
• fixed VT200-series soft-font loading which was not working.
• improved VT200 and VT300 custom block fonts. VT300 variant is still wrong but better.
• enable autowrap (DECAWM) after reset (DECSTR).
• re-enable the cursor before exiting.
• improved terminal detection.
• added '-r' option to rotate pieces counter-clockwise instead of the default clockwise.
• fixed potential crash when passing uninitialized buffer to JSIOCGNAME ioctl.

Changes:

• avoid crashes when an invalid tile is given to the display routine.
• wait for last blink to be completed before continuing, to avoid fast-forwarding for a few ticks after a line completion blink, on slow connections.

Changes:

Minor bugfixes in highscore handling in the DOS version:

• saving new score on gameover would result in a cycle in the scores linked list, printing the same high score multiple times.
• starting a new game would not re-read the high-scores keeping the same stale copy loaded by DOS on launch instead.

Changes:

• use custom soft-fonts for blocks on supported terminals (DEC VT200 and up).
• DOS: use custom soft-fonts for blocks on EGA or VGA/SVGA graphics cards.
• added key to display high score table while playing.
• added -a option for forcing the use of only basic ASCII characters.
• DOS: save highscores in the executable.
• DOS: fixed build with older versions of nasm.
• added -u option to override username for highscores.
• fixed build on SGI IRIX.
• fixed score file permissions during installation so that multiple users will be able to write to it.

Changes:

• Ported to DOS.

Changes:

• fixed: used to disable IXON for no reason, leading to garbled output on serial terminals relying on software flow control, at higher baud rates.
• stop relying on a COMMON section for globals, and dropped -fcommon.

Changes:

• Fixed build on GCC 10+ (-fcommon)
• Fixed bug allowing pieces to be dropped after game over.
• Better handling of screen clearing. Used to emit the hard reset command which recalls terminal settings, instead of the intended soft-reset.

Minor bug fixes and slightly improved build.

Changes since 1.2:

• fixed the spawn randomizer to correctly implement the gameboy algorithm
• lock pieces immediately when dropping them
• detect terminal size and center the playfield horizontally
• re-center whenever the terminal size changes
• commandline option for monochrome output
• pressing pause after a gameover restarts
• added controls to the usage information
• redraw the whole screen when backtick/tilde is pressed

termtris 1.2

• game restart with backspace or delete.
• saving highscores, and printing them with the -s command line argument.
• instant drop with tab, enter, or 0.
• bugfix: fail to clear the top part of the playfield when clearing lines, if blocks reached very high.
