doc: documentation changes
inf: informational only

v0.2.b8, 23-APR-2009:

- fix: joystick calibration and test widgets: check current joystick index correctly (also fixes build issues with gcc 4.4)
- fix: don't set InstanceRunning flag in the welcome dialog, but when the main widget is about to be setup (fixes cancelling/restarting with the welcome dialog)
- fix: completely removed buggy settings conversion code
- fix: ensure trailing slash for data-directory for path returned by standard dialog
- fix: corrected variant launch on Mac OS X -- now uses LaunchServices to locate the other variant
- fix: full ROM check: increase progress indicator during final determination of games/machines with a not found ROM status (or when the ROM states of all remaining systems need to become unknown due to interruption)
- fix: use rompath and samplepath only if they have been explicitly set, otherwise fall back to the default paths (roms, samples)
- fix: start emulator audit processes after their signals were connected (otherwise we can't be sure on all platforms that the QProcess::started() signal will be catched)
- fix: insert process map entry before starting the emulation (same reason as preceding fix)
- fix: ROM state toggles weren't correctly initialized at very first start
- fix: corrected position restauration of image checker dialog
- fix: completely rewrote the buggy obsoleteness check for ZIP'ed icons
- fix: corrected flakey sample check (output from emulator goes to both I/O channels -- stdout & stderr)
- fix: minor tool/status tip corrections for game/machine list status widget
- fix: fixed crashes when the game- or emulator-info widgets were visible during game-/machine-list reload
- fix: correctly update the ROM state toggles when the ROM state filter is changed through the options dialog
- imp: revised executable check of emulator binary to work platform independently
- imp: SDLMAME template updated to 0.131 (new option crsshairpath)
- imp: SDLMESS template updated to 0.130 (no new or changed options)
- imp: completely reverted the use of wildcards (*) on full audit calls -- makes more troubles than it brings benefits
- imp: ROMAlyzer: skip unsupported CHD formats
- imp: pressing Qt::Key_Escape in the emulator configuration does no longer open the alphanumeric search widget, but will close it if it's currently visible
- imp: updated template format to include the two new option types directory and file (new format version 0.2.2)
- imp: code cleanup: replaced all occurrences of getenv("HOME") with QDir::homePath() as it is more platform independent
- imp: print warnings to the front end log if emulator audit calls don't exit cleanly
- imp: ROM check: set ROM status of remaining games/machines to unknown if the emulator crashes while auditing
- imp: updated redistributed Qt translations to Qt 4.5.0
- imp: main widget improved to allow for even more layout flexibility
- imp: ROMAlyzer: changed some default settings to be more like "what the user expects"
- imp: earlier initial style setup, also circumvents a minor issue with the GTK+ style
- imp: worked around an annoying Qt bug that sometimes left the menu- and tool-bars at the wrong style or color palette (when changing the style dynamically)
- imp: removed icon-related GUI representations for MESS targets (there are no usefull MESS machine icons we're aware of)
- new: Mac and Windows only: show version of running OS on the sys-info page of the about dialog
- new: show Phonon runtime version on the sys-info page of the about dialog (if applicable)
- new: support for WindowsTM and the original versions of MAME & MESS (including some of their variants)
- new: added new template for the original version of MAME on Windows (see data/opt/MAME/template.xml, initial version 0.131)
- new: added new template for the original version of MESS on Windows (see data/opt/MESS/template.xml, initial version 0.130)
- new: added new template for MAMEUIFX32 on Windows (see data/opt/MAMEUIFX32/template.xml, initial version 0.131) -- use this template together with the MAME variant on Windows to cleanly support MAMEUIFX32 through QMC2
- new: added batch script for VC++ project file generation on Windows (see scripts/generate-vcprojects.bat -- preliminary, you'll have to adjust the path variables if you're going to use this script!)
- new: added new game/machine list setting called DoubleClickActivation to let the user enable/disable the start of an emulator on mouse double-clicks (may be annoying)
- new: build: added new VARIANT_LAUNCHER make option to enable/disable the QMC2 variant launcher at compile time (default: enabled on UNIX and Mac, disabled on Windows for now)
- new: ROMAlyzer: support for CHD v4
- new: show sort indicator in game/machine lists and let the user change the sort criteria & order by clicking an applicable column header
- new: provide file & directory browsers in emulator configuration widgets where applicable
- new: selectable tab positions (north, south, west, east) for the main widget -- changed via context menus
- new: support for additional artwork (cabinets, controllers, marquees and titles)
- new: print statistical ROM state info to front end log after game/machine list reload and ROM state checks
- doc: revised many paragraphs to better reflect platform-specific and common information

v0.2.b7, 09-MAR-2009:

- fix: ini-import/-export didn't work correctly when built for SDLMESS
- fix: clear search results list when search pattern is empty
- fix: ROMAlyzer: correctly reset the progress bar after analysing a game/machine for which the XML data indicates that it has no ROM files (MESS example: genesis)
- fix: corrected item cursor behavior in parent/clone hierarchy view on rapidly changing selections (i.e. when hovering over the list)
- fix: loading translations earlier now to allow for a translated welcome wizard
- fix: SDLMESS variant: store machine-specific emulator configurations in the [MESS] section
- fix: corrected a minor initial item selection issue for search results, play history and favorites lists
- fix: ensure a trailing slash for preview-, flyer- and icon-directories for paths returned by the directory selection dialog
- fix: corrected a series of bugs related to trimming the cached XML data -- if you don't update MAME/MESS when first using this (hopefully) fixed version of QMC2, it's recommended that you remove the gamelist- and XML-caches prior to starting QMC2 (the caches will be recreated cleanly)
- fix: ROMAlyzer: use full range of main progress bar
- fix: ROM state filter: correctly reset the progress bar after the filter has been applied
- fix: corrected a minor style setup issue on startup
- fix: ensure same minimum width for axis reset buttons of joystick calibration widget
- fix: honor UpdateDelay not only for previews & flyers, but also for all the other game/machine details
- fix: ensure main window is initially visible and not obscured by the menu bar
- fix: install target works with spaces in paths
- fix: center main widget on desktop if its restore position is yet undefined
- imp: build: added installation of desktop entry files
- imp: build: added optional support to build against a local / alternate SDL library (see new make options starting with SDLLOCAL) - the default is to use whatever SDL library the system may default to
- imp: SDLMAME configuration template updated to 0.130 (no new options)
- imp: SDLMESS configuration template updated to 0.129 (revised several option descriptions, removed remapjoys and remapjoyfile, added new options joy_idx1 - joy_idx8)
- imp: ROM status exporter: more SDLMESS specific updates to translatable texts
- imp: build: add qmc2.pro dependency for Makefile.qmake target
- imp: avoid potential locking during the determination of the emulator's version & supported games/machines due to a probably failed reception of the sub-process' finished() signal
- imp: ROMAlyzer: added more file status icons, log a warning on files with incorrect checksums
- imp: ROMAlyzer: show count down in analyzer status
- imp: code cleanup: replaced all occurrances of obsoleted QWidget method setShown() with setVisible()
- imp: code cleanup: use constants instead of numbers for logical emulator options columns
- imp: automatically fall back to parent's game/machine- and emulator-info records when necessary/possible
- imp: build: even nicer compile output
- imp: more flexibility to layout the main widget (note that this can lead to unusable sub-widgets if you overdo what's possible :)
- imp: ROMAlyzer: colorize wrong checksums in red, unknown states in blue
- imp: build: added new ARCADE_OPENGL make option - if enabled (default), QMC2's arcade mode will support OpenGL (if available - direct rendering/hardware acceleration recommended!), otherwise only the software renderer will be available (should be fast enough, though)
- imp: build: added new WIP make option - if set to 1, unfinished code will be made available (default = 0/disabled)
- imp: updated redistributed Qt translations to Qt 4.4.3
- imp: build: added new QT_TRANSLATION make option - set this to the absolute path to your Qt translation files if you don't want to use the ones which are redistributed with QMC2 (which is the default)
- imp: welcome wizard: remove initial sample path setup for MESS variant because MESS doesn't support samples anyway
- imp: added distribution specific build configuration for Mandriva Linux release 2009.0
- imp: use -listfull '*' / -listxml '*' (instead of just -listfull / -listxml) to determine the total number of supported games/machines and their detailed XML data - some MAME/MESS builds wouldn't report the full game/machine list without the asterisk
- imp: ROMAlyzer: log elapsed time after analysis
- imp: improved full screen toggling of main widget -- should work generally better now and be more independent of the window manager
- imp: build: out-of-the-box build support for Mac OS X (Darwin) -- thanks to Vas Crabb!
- new: log activation of joystick support and the run-time version of SDL (if applicable)
- new: show compile- and run-time versions of SDL in about dialog (if applicable)
- new: log run-time version of Phonon (if applicable)
- new: added new setting ParentImageFallback (default: false) to enable falling back to the parent's image if an individual clone's image doesn't exist (but the parent's image does)
- new: added optional/on-demand vertical status indicator in game/machine detail view
- new: added optional/on-demand display of game/machine description in preview & flyer images
- new: added new setting ShowMenuBar (default: true) to control the menu bar visibility
- new: MESS: full device support through the new MESS device configurator, which is integrated into the main widget
- new: added ROM state filter toggles to the main widget, including new short cuts
- new: added new setting CheckSingleInstance (default: true) to enable/disable a startup check against multi-instance runs of the same QMC2 variant
- new: all QMC2 variants are now separately configured - includes automatic settings conversion (if required) and automatic cloning of a probably already existing front end configuration (from another variant)
- new: added runonce utility to project for use with the QMC2 variant launcher
- new: QMC2 variant launcher: both QMC2 variants (qmc2-sdlmame & qmc2-sdlmess) can launch one another; if the other variant already runs, try raising it - note that this feature is very dependent on the window manager which may decide to ignore XMapRaised(); on KDE for example, it will only work correctly when focus under mouse or focus strictly under mouse has been set!)
- wip: arcade mode (not working in this release -- disabled by default -- use "make WIP=1 ..." for a preview)
- doc: added Q2.11 to FAQ
- inf: checked SDL 1.3 (experimental!) compatibility of joystick API
- inf: trying to build with Qt versions less than 4.4.0 is now completely inhibited!
- inf: long project name changed to M.A.M.E./M.E.S.S. Catalog / Launcher II
- inf: build: compile time measurement is disabled per default now
- inf: there's nothing like an emulator info DB for MESS, so this feature is completely disabled in case of QMC2 for SDLMESS
- inf: project home page moved to http://qmc2.arcadehits.net/ -- thanks to Vincent Bousquet
- inf: checked Qt 4.5+ compatibility (recommended due to much better performance!)

v0.2.b6, 05-JAN-2009:

- fix: startup crash on the creation of the template configuration map under certain circumstances (see tracker #2201714)
- fix: worked around a minor Phonon issue with duplicate metaDataChanged() signals
- imp: SDLMAME options template updated to 0.129 (corrected default value for audio_latency, revised several option descriptions, removed remapjoys and remapjoyfile, added new options joy_idx1 - joy_idx8)
- imp: updated template format to include the template's emulator name (new format version 0.2.1)
- imp: ROMAlyzer: determine ROM file CRC identification troubles in ZIPs, log warnings and set the file status to bad in such a case (in contrast to not found as before)
- imp: code cleanup: changed several macro definitions to be consistent within QMC2's namespace
- imp: build: added new make options DISTCC, DISTCC_CC & DISTCC_CXX (uses a distributed compiler such as distcc or icecc if DISTCC is set to 1 - check/set DISTCC_CC / DISTCC_CXX if enabled!)
- imp: slightly improved welcome dialog (logo, button icons and layout)
- imp: build: preserve existing system-wide configuration (usually /etc/qmc2/qmc2.ini) on make install
- imp: build: avoid overwriting the Makefile when qmake is accidently called standalone (the project file now sets QMAKE_MAKEFILE to Makefile.qmake)
- imp: build: allow pretty compile output (doesn't work for RCC yet due to a qmake bug) - enabled per default, use make PRETTY=0 to disable
- imp: build: splitted CCACHECMD into CCACHE_CC & CCACHE_CXX
- imp: build: use the same qmc2.pro project file for both debug and release builds (adding CONFIG settings dynamically on qmake call)
- imp: ROMAlyzer: log more CHD v3 header information (CHD tag, writable flag and parent's MD5/SHA1 checksums, if applicable)
- imp: ROMAlyzer: if romof is set in a game's XML data, but the file to merge is missing from this data (= merge attribute is empty), recursively search for the name of the current game's ROM file instead - MAME does exactly this in these rare cases (example: sfiiin)
- imp: ROMAlyzer: produce better status and log information on CHDs that were not found
- imp: allow higher values for gamelist responsiveness - setting this value higher than the total number of games will usually allow for less than 2 seconds of gamelist processing (at the expense of a more or less unresponsive GUI during reload, of course)
- imp: updated XML game info parser to support all current game/machine settings from MAME/MESS
- imp: many [Frontend] settings moved to [MAME] and [MESS] sections (automatically converted if the previous version is less than 0.2.b6)
- imp: code cleanup: make class and variable names emulator independent (i.e. use EmulatorOptions instead of MameOptions)
- new: added new SDLMESS options template (see data/opt/SDLMESS/template.xml, initial version 0.128)
- new: experimental support for SDLMESS (status: very basic and no device support yet)
- new: added plugin helper sample script for emulator startup interception (see scripts/plugin_helper.sh)
- new: all UI files regenerated with Qt 4.4's designer - Qt 4.4.0+ promoted as the new required version, although you may still be able to build it using Qt 4.3 in the short term - Qt 4.3 is no longer supported!
- new: added tab icons for all main widget functions
- new: ROM status export tool with support for ASCII, CSV and HTML output formats - can output to file or clipboard
- doc: added Q2.10 to FAQ
- doc: added Ubuntu 8.10 (Intrepid) as an officially tested distribution to the FAQ (see Q1.7.1)
- doc: added Fedora release 10 as an officially tested distribution to the FAQ (see Q1.7.3)
- doc: added openSUSE 11.1 as an officially tested distribution to the FAQ (see Q1.7.2)

v0.2.b5, 16-OCT-2008:

- fix: corrected a serious bug in ROM state and gamelist caching introduced by trimming the data - please remove all cache files from previous releases before using this version, otherwise QMC2 is likely to crash (rm ~/.qmc2/mame.lxc ~/.qmc2/qmc2.rsc ~/.qmc2/qmc2.glc)
- fix: corrected the shortcut scope of several actions
- fix: ROMAlyzer (cosmetic): don't start analyzing if the gamelist is empty

- imp: build: added new make option PHONON (enables Phonon based features if set to 1, which is the default for Qt 4.4+)
- imp: revised a number of menu item texts
- imp: layout improvements for the ROMAlyzer (file I/O indicator now vertical)
- imp: code cleanup: prepend QMC2_ to SDLMAME macro internally
- imp: build: added new make options CCACHE & CCACHECMD (uses ccache compiler cache if CCACHE is set to 1; default is 0 - check/set CCACHECMD if enabled!)
- imp: exchanged Qt logo due to Qt rebranding as of 4.4.3
- new: support for MAME output notifications via a named pipe (SDLMAME 0.127+)
- new: emulator control panel changed to a multi-column tree widget displaying more information like the game name, its LEDs (if applicable), the current emulator status and additional notifiers/values not handled statically (in a sub tree)
- new: added a copy command menu item to the emulator control panel's context menu to allow for easier copying of emulator command lines to the system clipboard
- new: individual joystick axes can now be enabled/disabled at will (this should make Sixaxis users happy :)
- new: the number of lines kept in the ROMAlyzer log can now also be limited
- new: optional support for background music playback (requires Qt 4.4+ / Phonon API - feature will be completely disabled for Qt 4.3)
- new: the boolean emulator option values true and false are now also translatable
- doc: added Q2.9 to FAQ

v0.2.b4, 19-AUG-2008:

- fix: joystick mapping initially didn't work before the options were explicitly applied
- fix: keep game-specific emulator configurations open only as long as they are really needed
- fix: corrected support for keyboard shortcut mapping with multiple modifier keys
- imp: try to use system locale to setup the language if no language was specified (or if the language is unavailable within the translations); fallback to us as last resort
- imp: joystick test and calibration widgets are enclosed in scrollable areas now to allow for better handling of high amounts of axes or buttons; due to this, the layout management for these widgets was totally revised
- imp: minor speed ups for loading of XML and gamelist caches by reading data block-wise
- imp: SDLMAME options template updated to 0.127 (yuvmode replaced with scalemode, removed cheat_file, added new options cheatpath, videodriver, audiodriver and gl_lib)
- imp: code cleanup: use constants instead of numbers for logical gamelist columns, prepend QMC2_ to JOYSTICK and OPENGL macros internally
- imp: trimmed XML cache data - saves memory and disk space (plus adds a minor speed improvement upon cache reading)
- imp: build: check required Qt version on call to qmake (see qmc2.pro*)
- new: show number of (real/virtual) CPUs on system information page (about dialog)
- new: the frontend and emulator log browsers can now be limited to the amount of lines they keep in memory (the default is unlimited as before)
- doc: added Q2.8 and Q3.5 to FAQ

v0.2.b3, 07-JUL-2008:

- fix: if a null pixmap was retrieved, display the ghost image instead (of nothing)
- fix: under rare circumstances, the game specific emulator configuration wasn't updated correctly (empty widget)
- fix: positions of about dialog and doc browser were incorrectly restored on showEvent()'s
- fix: when switching between detailed gamelist and parent/clone hierarchy during reload, QMC2 crashed under certain circumstances (not absoluteley sure if this bug existed before or if it was introduced by new features of this release :)
- fix: avoid auto-selecting first game in list if switching views during gamelist reload
- fix: adjust icon sizes of shortcut redefinition buttons
- fix: restore "Default" style selection correctly after language switch

- imp: use QWidget instead of QFrame for (standard) preview & flyer widgets
- imp: enabled on-the-fly switching to system default style
- imp: all independant widgets (dialogs) are now explicitly created as sub-windows which allows them to be individually minimized / restored regardless if they have parents or not (new window flags: Qt::Dialog | Qt::SubWindow)
- imp: build: added support for distribution specific build on openSUSE 11.0, Fedora release 9 and Yellow Dog Linux 6.0
- imp: build: moved os-detect.sh to scripts/ directory (where it belongs :)
- imp: build: changed os-detection to be architecture independant for Linux distributions
- new: optional use of OpenGL to draw images (previews & flyers) - decided at compile time with the new OPENGL make option (OPENGL=0 is the default and paints on a normal QWidget; using a QPainter on a QGLWidget is actually a bit slower)
- new: optional direct GUI control via digital and analog joysticks (joystick support is enabled by default, use make option JOYSTICK=0 to completely disable it - note that compilation of QMC2 with enabled joystick support requires an SDL 1.2.11+ development package to be installed on your system!)
- new: support for MAME's history.dat game information database
- new: support for MAME's mameinfo.dat emulator information database
- new: show memory information (total, free, used) in about dialog (see system info)

- new: game's short name (game ID) now also included in gamelist, plus added sorting by game name
- inf: SDLMESS can only be used when compiled against the MAME target, of course :)

- fix: minor translation fixes
- fix: corrected (hidden) selection of filtered games
- fix: worked around a Qt bug when POS1/Home is pressed and the first item in the gamelist is hidden due to ROM state filtering; QMC2 now selects the first VISIBLE entry instead
- fix: fixed several item selection bugs when changing between lists (gamelist, search results, favorites and play history) - note that this fix is only effective, if Qt 4.3+ is used
- fix: when switching back to the (full-detail) gamelist view, the next item selection issued by a mouse-click wasn't correctly recognized
- fix: corrected unwanted double paint-event when selecting games through the parent/clone hierarchy view
- fix: make MAME executable setting unchangeable during gamelist reload

- new: added ROMAlyzer script from Carsten Engel (see scripts/romalyzer.pl) - WORK IN PROGRESS
- new: BIOS ROMs are now also supported (but obviously cannot be run); the ROM status icon will contain a white "B" to indicate that this is a BIOS (when using the classic image set)
- new: determination of MAME and configuration template version (see frontend log)
- new: added gamelist cache to speed up reload process; the cache will be automagically recreated if the MAME version changes or QMC2 thinks the cache is invalid / out-of-date

- new: added new setting RetryLoadingImages: if unset, QMC2 will cache the ghost image where no images were found (default: true, current behavior)
- new: added new setting StandardColorPalette: if unset, QMC2 will use the custom palette which may have been setup with qtconfig (default: true, current behavior)
- new: image set support - select at compile time with new IMGSET variable (default "classic", alternative image sets "crazy" and "crazy-black" by Armin Schmidhuber)
- new: added new setting AutoTriggerROMCheck: if set, QMC2 will automatically trigger a ROM check if necessary (default: false, current behavior)
- new: reload gamelist automatically if MAME executable changes
- new: added new setting UpdateDelay; controls the delay in milliseconds between a game's selection and the update of its preview, flyer or MAME configuration
- new: if Qt 4.3+ is used, QMC2 will now save & restore the header states of all tree-widgets, except the game specific MAME configuration widget which is too temporary to be valuable for save/restore
