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)
