The Windows version looks almost stable, but the GTK version fails in some cases.
That's why the classic wx debugger is still available if BX_DEBUGGER_GUI is set to 0.
- added function close_debug_dialog() to handle the simulation stop case in wx
- disable all the wx debugger related code if BX_DEBUGGER_GUI is set to 1
- added enhanced debugger specific init code similar to the code in sdl.cc
- include debugger related resources on Windows
- TODO: make the GTK / wxGTK case stable and remove the wx debugger
- isempty() returns 1 if string length is 0 or string has special value "none"
- sprint() copies the formatted / converted string into a buffer
- use new methods in some parts of the code (TODO: win32 dialogs)
- check for the special value "none" to avoid failures
- moved 'user_shortcut' option to the keyboard option
- added new bx_param_c option value BOCHSRC_HIDDEN for parameters that should
only be available in the config interface. The new bochsrc option save and
parser function skip parameters with this flag set. This is useful for
parameters that will be set from the parser in a different way.
- save keyboard bochsrc line using the parameter list directly
- parse keyboard bochsrc options (except 'keymap') using the parameter list
- user shortcut: old-style syntax has already been removed
- increased minimum value for the keyboard's 'serial_delay'
- removed parameter "present" and use the new drive type "none" instead
- re-implemented cdrom media status parameter as a bx_param_enum_c
- TODO: change floppy media status parameter type to be consistent
- fixed bochsrc line after a "raw byte" string parameter
- changed parameter name "macaddr" to "mac" (same as bochsrc option parameter)
- skip disabled parameters when building the bochsrc line
- added "multiline" switch to select the output format (one or multiple lines)
- renamed siminterface method and use it in the network devices code
- renamed config parameter "i440fx_support" to "enabled"
- new config parameter "chipset" added (current choices "i430FX" and "i440FX")
- don't load ACPI support if the i430FX chipset is selected
- select register values for the core PCI devices depending on the chipset
- USB UHCI must be connected to a PCI slot if the i430FX chipset is used
- rombios changes to make the i430FX chipset work
- TODO #1: implement limitation to 1 cpu and 128 MB RAM for the i430FX chipset
- TODO #2: verify register behaviour of both chipsets
- renamed trigger_timer() methods to refresh_display()
- new argument 'redraw' added to force a refresh of the entire screen
(used in snapshot mode)
- siminterface method refresh_vga() now checks if the Bochs gui init is complete
- use SIM->refresh_vga() in some more cases
- graphics_tile_info() split into a common and specific part
- store snapshot mode in structure bx_svga_tileinfo_t
- in snapshot mode, display adapters copy raw data to buffer
- rewrite of the trigger_timer() code to make it work in all cases
- added new class bx_nonvga_device_c to make forwarding refresh requests to the
Voodoo adapter possible
API) moved to the gui code. Splitted graphics_tile_update() in a common and a
specific part. The common part handles the snapshot case if active. As a side
effect, the snapshot feature now works for CGA modes, too. Fixed palette colors
in 8 bpp snapshots.
the display adapter code. When ready, the common gui code should handle it
completely. The snapshot handler should set a flag 'snapshot_mode' and then it
should force a display update. The graphics update code should be redirected to
some code that 'draws' to a snapshot buffer. These first steps are done:
- store some guest display settings in the gui code (text / graphics switch,
x / y resolution and bpp)
- split 8 bpp palette update code in a common and a specific part and store the
palette values in the gui code

is currently written for flat, sparse and growing images. The undoable and
volatile mode now cause a panic if the r/o image mode is unsupported.

them usable for autodetection.
- TODO #2: add support for other types of r/o disks in undoable/volatile mode.

support is implemented and the specific save function is only written for
flat mode images (copies whole disk image file to the save/restore folder).
- TODO #1: implement save function for the other disk image modes
- TODO #2: add restore support (replace disk image file with the one from the
save/restore folder)
- re-implemented siminterface method is_wx_selected() (the old one had been
renamed to has_debug_gui() which is something different now)
- don't use alarm() if the wx gui is selected and instead use the wxTimer based
code that already exists for wxMSW
Added a new event BX_ASYNC_EVT_QUIT_SIM that is posted from the simulation thread
to the gui thread and the "Bochs stopped" message box is shown there.
- TODO: Fix random freezes in wxGTK that seem to be caused by the "show ips"
feature. A async event like the one above could possibly fix this problem.

- siminterface / wx: updated / added comments
- renamed wxWidgets README (some more updates may be required)
- TODO: fix deadlock after pressing the power button (wxGTK only)
- uninstall parameter handlers (floppy, keyboard)
- unload plugin that cannot be removed automatically
- wx: removed "show keyboard" demo and some other cleanups
- TODO: remove wx debugger and make wx work with the enhanced gui debugger
- ported Qemu block driver (written by Alex Beregszaszi and Kevin Wolf)
- added helper functions bx_read_image() and bx_write_image()
- TODO: use helper function for the other disk image modes
- SIM->opt_plugin_ctrl() now can be used to verify the optional plugin
configuration when using the plugin name "*". The 'load' value 1 makes
sure that all plugins with the value 1 are loaded. The 'load' value 0
unloads all plugin with the value 0 (marked for removal).
- add the default set of plugins to the 'plugin_ctrl' list and load all these
pre-defined optional plugins before parsing the configuration.
- special wx case: verify plugin configuration before showing the plugin
control dialog and before initialising hardware.
- device plugins that have been loaded, but not configured now set their
plugin control value to 0. Added the plugin unload check before signalling reset.
- enh_dbg: fixed defined-but-not-used warnings
- siminterface: renamed 'wx_debug_gui' to 'bx_debug_gui' and updated comments
- TODO: remove the wx debugger and use the enhanced gui debugger instead
- new gui method set_mouse_mode_absxy() should switch the gui to absolute
x/y mode
- new DEV_mouse_motion() argument 'absxy' indicates whether or not the gui
sends absolute x/y values
- USB tablet code prepared to use the new feature
- TODO: implement this feature for each gui (sdl, win32, wx, x, ...)

-1 to avoid unwanted modification. NOTE: Not all Bochs modules exist when
running the start menu / dialog.
- siminterface: don't create plugin parameter if it already exists
- wx: make sure all plugins are loaded when creating plugin control dialog
- USB HC's: fixed removal of parameters when unloading plugin
also works and no deplist trick is required
- bx_param_c destructor now deletes the dependent list if it exists (memory leak)
- bx_list_c::clear() only deletes the parameter if the list is it's parent
- added new method cleanup_save_restore() to free memory on simulator shutdown
- bx_list_c: don't accept duplicate param names in list (except dependent lists
and special menus)
- added BX_PANIC for malloc() failure
- harddrv: fixed wrong variable found with bx_list_c changes
- changed argument for the text mode info structure to a pointer
- added attribute controller palette to bx_vga_tminfo_t and removed the
previous implementation
- carbon.cc: attempt to fix the text mode colors (untested)
- x.cc: fixed warnings

- TODO #1: win32.cc also shouldn't include vga.h
- TODO #2: replace BX_MAX_XRES / BX_MAX_YRES by variables that can be set
depending on the configuration

existing "iolight timer" code in the hard drive code. If an LED is registered
with the "auto-off" flag, the device only needs to turn on the LED to indicate
data transfer. The LED timer in the gui code turns it off after 0.5 seconds if
it is not actived by another transfer. Added this feature to all network
devices.

with the host time. After using a runtime config dialog or save and restore
simulation, this behaviour makes the PIT clock and the VGA update timer
running way too fast until it's back in sync. Now the elapsed time is stored
in the variable 'real_time_delay' and it is used to let the PIT clock run at
realtime speed, even if it is out of sync.
- fixed size entries in bitmap file header for 8 bpp
- bx_param_filename_c now uses the file extension from the initial value as
the default (if present)
- SIM->ask_filename() now uses the correct parameter type

Desription for CHANGES:
- Memory
- Added new configure option which enables RAM file backing for large guest
memory with a smaller amount host memory, without causing a panic when
host memory is exhausted (patch by Gary Cameron). To enable configure with
--enable-large-ramfile option.
* moved runtime handlers for cdrom from config.cc to the device object
* cd media status variable is now always of type bx_bool
* changed obsolete gui names like "cdromD" to "cdrom1"
* TODO: implement new runtime config mechanism similar to USB
each other. Devices can register a handler to update it's state after runtime
configuration. The new method update_runtime_options() executes all registered
device handlers before the simulation continues.
- USB host controllers now using the new mechanism to handle the runtime device
change (replaces the previous timer-based implementation). TODO: floppy and
cdrom could use this feature, too)
- improved USB device change messages
DAC2 is sent to the lowlevel sound module. DAC1 and sound input (ADC) are not
yet supported. Also unsupported: CODEC (mixer), UART (MIDI) and legacy support.
Sound module selection in configure script now no longer depends on SB16 and
uses autodetection only.
- fixed segfault when saving bochsrc
* ported the read part of the Qemu vvfat block driver
* added win32 specific directory functions (required for MSVC)
* TODO: write support, FAT32 support, read MBR and boot sector from file
- siminterface: added helper method hdimage_get_mode()
- moved hdimage related stuff from harddrv.cc to the hdimage code
- changed hdimage related names
