2002-04-02      src/events.c, src/editor.c
        * Make Escape key less aggressive when playing or when editing level.
          This can be configured as an option in the setup menu. (Default is
          "less aggressive" which means "ask user if something can be lost"
          when pressing the Escape key.)

2002-04-02      src/screen.c
        * Added "graphics setup" screen.

2002-04-01      src/screen.c
        * Changed "choose level" setup screen stuff to be more generic (to
          make it easier to add more "choose from generic tree" setup screens).

2002-04-01      src/config.c, src/timestamp.h
        * Added source files "src/config.[ch]" and "src/timestamp.h" (which
          automatically gets created by "src/Makefile" and contains an actual
          compile-time timestamp to identify development versions of the game).

2002-03-31      src/tape.c, src/events.c
        * Added quick game/tape save/load functions to tape stuff which can be
          invoked by a keyboard shortcut. Default: "F1" saves game/tape, "F2"
          loads previously recorded tape and directly goes into recording mode
          from the end of the tape (therefore appending to the tape).

2002-03-31      src/tape.c
        * Added "index mark" function to tape recorder. When playing or
          recording, "eject" button changes to "index" button. Setting index
          mark is not yet implemented, but pressing index button when playing
          allows very quick advancing to end of tape (when normal playing),
          very fast forward mode (when playing with normal fast forward) or
          very fast reaching of "pause before end of tape" (when playing with
          "pause before end" playing mode).

2002-03-30      src/cartoons.c
        * Moved some stuff from cartoons.c to the new "src/libgame/toons.c".

2002-03-29      src/screen.c
        * Changed setup screen stuff to be more generic (to make it easier
          to add more setup screens).

2002-03-23      src/main.c, src/main.h
        * Various changes due to the introduction of the new libgame files
          "setup.c" and "joystick.c".

2002-03-23      src/files.c
        * Generic parts of "src/files.c" (mainly setup and level directory
          stuff) moved to new libgame file "src/libgame/setup.c".

2002-03-23      src/joystick.c
        * File "src/joystick.c" moved to libgame source tree, with
          correspondig changes.

2002-03-22      src/screens.c
        * "HandleChooseLevel()": Another bug in level series navigation fixed.
          (Wrong level series information displayed when entering main group.)

2002-03-22      src/editor.c
        * Slight change to support new gadget event "GD_EVENT_INFO_LEAVING".

2002-03-22      src/editor.c
        * Changed behaviour of "Escape" key in level editor to be more
          intuitive: When in "Element Properties" or "Level Info" mode,
          return to "Drawing Mode" instead of leaving the level editor.

2002-03-21      src/game.c, src/editor.c, src/files.c
        * 2.0.1 introduced the corrected "Emerald Mine" style behaviour of
          gems (emeralds, diamonds, ...) slipping down from normal wall,
          steel wall and growing wall (as in E.M.C. style levels). Although
          the behaviour of contributed and private levels wasn't changed (due
          to the use of "level.game_version"; see previous entry), editing
          those levels will (of course) change the behaviour accordingly.

          This change seems a bit too hard after thinking about it, because
          the EM style behaviour is not the "expected" behaviour (gems would
          normally only slip down from "rounded" walls). Therefore this was
          now changed to an element property for gem style elements, with the
          default setting "off" (which means: no special EM style behaviour).
          To fix older converted levels, this flag is set to "on" for pre-2.0
          levels that are neither contributed nor private levels.

2002-03-20      src/files.h
        * Corrected settings for "level.game_version" depending of level type.
          (Contributed and private levels always get played with game engine
          version they were created with, while converted levels always get
          played with the most recent version of the game engine, to let new
          corrections of the emulation behaviour take effect.)

2002-03-20      src/main.h
        * Added "#include <time.h>". This seems to be needed by "tape.c" for
          compiling the SDL version on some systems.
          Thanks to the several people who pointed this out.

2002-03-19
        * Version number set to 2.0.2.

2002-03-19
        * Version 2.0.1 released.

2002-03-18      src/screens.c
        * "HandleChooseLevel()": Small bug in level series navigation fixed.

2002-03-18      src/files.c [src/libgame/misc.c]
        * Moved some common functions from src/files.c to src/libgame/misc.c.

2002-03-18      src/files.c [src/libgame/misc.c]
        * Changed permissions for new directories and saved files (especially
          score files) according to suggestions of Debian users and mantainers.
          Thanks to Drew Parsons <dparsons@emerall.com> for the patch.

2002-03-17      src/files.c
        * Changed "{Load|Save}{Level|Tape}()" to IFF style file format:
          Replaced "cookie" header string ("ROCKSNDIAMONDS_...\n") with
          real IFF style header "RND1....XXXX" (where "XXXX" is "CAVE"
          for levels and "TAPE" for tapes). Old "cookie" style format is
          still supported for reading. New level and tape files are written
          in new format.

        * New IFF chunk "VERS" contains version numbers for file and game
          (where "game version" is the version of the program that wrote the
          file, and "file version" is a version number to distinguish files
          with different format, for example after adding new features).

2002-03-15      src/screen.c
        * "DrawHallOfFame()": "FadeSounds()" when entering the hall of fame.
          (Before, you heard a mixture of the in-game music and the
          hall-of-fame music.)

2002-03-14      src/events.c
        * Function "DumpTape()" (files.c) now available by pressing 't' from
          main menu (when in DEBUG mode).

2002-03-14      src/game.c
        * "GameWon()": When game was won playing a tape, now there is no delay
          raising the score and no corresponding sound is played.

2002-03-14      src/files.c
        * Changed "LoadTape()" for real chunk support and also adjusted
          "SaveTape()" accordingly.

2002-03-14      src/game.c, src/tape.c, src/files.c
        * Important changes to tape format: The old tape format stored all
          actions with a real effect with a corresponding delay between the
          stored actions. This had some major disadvantages (for example,
          push delays had to be ignored, pressing a button for some seconds
          mutated to several single button presses because of the non-action
          delays between two action frames etc.). The new tape format just
          stupidly records all device actions and replays them later. I really
          don't know why I haven't solved it that way before?! Old-style tapes
          (with tape file version less than 2.0) get converted to the new
          format on-the-fly when loading and can therefore still be played;
          only some minor parts of the old-style tape handling code was needed.
          (A perfect conversion is not possible, because there is information
          missing about the device actions between two action frames.)

2002-03-14      src/files.c
        * New function "DumpTape()" to dump the contents of the current tape
          in a human readable format.

2002-03-14      src/game.c
        * Small tape bug fixed: When automatically advancing to next level
          after a game was won, the tape from the previous level still was
          loaded as a tape for the new level.

2002-03-14      src/tape.c
        * Small graphical bug fixed: When pressing ""Record" or "Play" on
          tape, cartoons did not get completely removed because
          StopAnimation() was not called.

2002-03-13      src/files.c
        * Changed "LoadLevel()" and "SaveLevel()" to add new chunk "CNT2".
          Fixed bug of "CONT" and "BODY" (chunk size was set to 8-bit element
          size even when using 16-bit elements). Added new chunk "CNT2" for
          16-bit amoeba content (previously written in 8-bit field in "HEAD"
          chunk even when content was 16-bit element). "CNT2" should now be
          able to store content for arbitrary elements (up to eight blocks of
          3 x 3 element arrays). All "CNT2" elements will always be stored as
          16-bit elements. "CONT" (with 8/16-bit elements) now obsolete.

2002-03-13      src/files.c
        * Changed "LoadLevel()" for real chunk support.

2002-03-12      src/game.c
        * Fixed problem (introduced after 2.0.0 release) with penguins
          not getting killed by enemies

2002-02-24      src/game.c, src/main.h
        * Added "player->is_moving"; now "player->last_move_dir" does
          not contain any information if the player is just moving at
          the moment or not.
          Before, "player->last_move_dir" was misused for this purpose
          for  the robot stuff (robots don't kill players when they are
          moving). But setting "player->last_move_dir" to MV_NO_MOVING
          broke tapes when walking through pipes!
          ("IS_MOVING()" uses "MovPos[][]", but this fails when it is 0
          in a continuous movement. This fact is ignored for friends and
          enemies, though.)
