Changelog for MegaZeux 2.84c

Dec 22, 2012 - MZX 2.84c

Hey all, new version of MegaZeux here! And hopefully without any
crashes this time around!  Haha yeah right.

The most notable thing this release (besides fixed crash bugs,
as usual) is the new counter debugger! Give it a try and tell us
what you think!

Counter binary search has been replaced with a hash table in
versions of MegaZeux for most platforms. This has resulted in
slightly faster counter lookups, and MUCH faster creation of
counters, since MegaZeux doesn't have to keep the list ordered.
The hash table is turned off for NDS builds for now due to tight
memory constraints.

Otherwise, most of the new features are editor enhancements and
modifications. Notable mentions are reordering the board list
with 'M' and a custom undo history size.

FEATURES

+ The functionality of the F11 counter/string debugger has been
  expanded to include sprites, robots, and miscellaneous world
  and board variables. The ability to modify many of these vars
  is limited and a large portion are read-only. In addition, you
  may add new counters and strings, hide empty counters/strings
  (does not affect built-in variables), and search by name and
  contents. Export is still limited to counters and strings.
+ Max string length has been increased from 1MiB (1048576 bytes)
  to 4MiB (4194304 bytes).
+ Board mods may now be selected from subdirectories of the game
  folder in the ALT+N dialog.
+ The title bar now displays the world and editing board/robot
  names based on context.
+ Fire Burns Space and Fire Burns Forever are off by default.
+ You may now specify the size of the undo history in the char
  editor, and the history affects the entire char set. Undo is
  still ALT+U, redo is now ALT+R.
+ You may now use the -/+ keys in the world editor to move to
  the previous/next boards in the board list, and Shift+Arrows
  to change to the boards linked by board edge.
+ You may now move the current board anywhere in the board list
  with M. You may not move the title screen board.
+ View mode in the board editor (V) will start from the current
  location of the screen now rather than at the top-left corner.
+ Config file options for default board settings added, as well
  as the ability to save these per-world from the editor.
+ Ctrl+G - Goto board position at X,Y.
+ png2smzx now requires less arguments and has an option to skip
  a char (generally char 32 will be useful to skip).

+ Debytecode: The robotic editor now asks for a confirmation to
  save the program on exit.

BUGFIXES

+ Fixed a bug in the 'glsl' renderer that caused the cursor
  color to be ignored (always white). This caused the cursor to
  not be visible if shown on a white background. (ajs)
+ Setting $string.length will not cause memory corruption now.
  In addition, its pre-2.84 behavior of intentionally allocating
  the string past the set length has been restored, but the
  length itself will still be set to the correct value.
+ Added bounds check to INC "$string" "value". Attempts to
  increase a string past its maximum length (4 MiB, or 4194304
  bytes) will now fail.
+ Fixed MegaZeux crash that could sometimes occur when a string
  was increased by itself.
+ Fixed MegaZeux crash that could occur when exiting the editor
  to a world file that failed validation.
+ Rolled string->storage_space into string->name to prevent
  buffer overflow errors and crashes. (Mr_Alert)
+ Fixed crash that would occur when attempting to type in a dir
  in the ALT+N dialog.
+ Fixed a bug where copy block $string would apply REL twice.
+ Thanatos Insignia (DoZ Q1 2011, 98485) will now play without
  freezing both normally AND after loading a save. Robots will
  not be incorrectly versioned with the save format magic now.
+ Fixed bug where ALT+M wouldn't always edit non-stored types.
+ Fixed bug where ! could not be used as a substitute for ~.
+ Fixed a bug where tab-draw and block actions would carry
  between board and overlay editing. ALT+O now sets the drawing
  mode back to normal on a switch.
+ ALT+M now edits the overlay instead of the board while editing
  the overlay.
+ Quick-load (F10 during gameplay) will not work if the load
  menu (F4) has been disabled with the LOAD_MENU counter.
+ Fixed a bug where the listening mod directory would stay the
  same as the directory the editor was opened in.
+ The listening mod now continues to play after world and board
  changes, and also after the board mod has been changed by
  ALT+N or Shift+8/*.
+ LOAD_GAME will not incorrectly trigger JUSTENTERED anymore.
+ Palette/intensity changes made on the same cycle as a teleport
  player command are now properly taken into account. This fixes
  a game-stopping regression in Sponkgo's Legendary Journey
  where leaving the second stage's bonus area would leave the
  color intensity at 0.
+ SMZX mode is now disabled when leaving the editor if it was
  enabled in the editor via F11.
+ Fixed potential crash bug where robot bytecode files were not
  being validated before being loaded with LOAD_BC.
+ Fixed minor message box bug dating back to DOS where a message
  box starting with an unavailable option would begin with the
  cursor on a blank line.
+ Fixed crash that happened when typing over bounds while
  renaming a file in a file manager dialog. File and directory
  renaming now use a popup dialog akin to ALT+N.
+ Files with names longer than 55 chars may now be selected in
  file managers. The limit for typing in a file name is still 55
  chars.  You may not enter a blank line as a file name anymore.
+ Fixed segfault when attempting to read THIS_COLOR for the
  global robot. It will now always return -1.

DEVELOPERS

+ Overhauled txt2hlp. Error messages now differentiate between
  hyperlinks and labels and will take the display chars ~ and &
  into account. Eventually, the goal should be to get rid of
  txt2hlp altogether and have MZX load straight from the .txt
  file.
+ Added compile option to use uthash for counter/string lookups
  as opposed to binary search. Ideally, this will vastly improve
  lookup speeds for large numbers of counters/strings, but will
  consume more memory. (thanks to Lancer-X for the modified
  uthash header file)
