0.2.5 (released 20 September 2008) adds the following features:

* GMAMEUI now supports MAME 0.127. Fixed SF bug 2076562 (unknown option: -yuvmode) by validating supported MAME options prior to launching ROM
* Modified handling of MAME audit processing to catch ROM errors and properly display invalid ROMs. Samples now shows Not Available samplesets
* Italian translation 100% (thanks Ugo Viti)
* Missing/invalid ROMs now reported properly upon launch
* Main window remembers settings on disabling/enabling filter list, sidebar, toolbar and statusbar on startup
* If no preferences file is available, or values are missing, use default values for the UI
* Load and set joystick value in GUI Prefs dialog
* Mark new source files as translateable, mark new strings as translateable, modify Makefile for better RPM support (SF patch 2035285 - thanks Ugo Viti). Italian translation is now at 100%.
* Set default button on the dialogs to be the Close button
* Added support to launch the GMAMEUI Help manual. This will use gtk_show_uri (if GTK > 2.13 is installed), or revert to libgnome´s gnome_url_show. Users who do not wish to compile in libgnome (e.g. XFCE or KDE users) will need to explicitly disable it by compiling with --disable-libgnome, but will not be able to access the manual from within GTK
* Apply patch to allow RPM build (thanks Ugo Viti)
* Other code changes
o Consolidated code to retrieve images from zip files
o Fix many compilation warnings
