Jun 13, 2001 - 17:25 added DirectDraw and DirectInput8 init routines for the new Windows port of Caprice32
Jun 13, 2001 - 20:50 keyboard emualtion works now via the DI8 action mapping
Jun 21, 2001 - 00:30 changed DDraw code to work in windowed mode; added routines to render CPC screen in 32bpp; added drag'n drop functionality for CPC drive A
Jun 23, 2001 - 16:15 only the visible portion of the CPC screen is rendered to the frame buffer; Windows window is now sized to the proper CPC screen dimensions
Jun 28, 2001 - 18:42 fixed the extended DSK parsing; loading DSK images via common dialog file selector; handling of joystick axis data
Jun 29, 2001 - 20:16 speed throttling to original CPC speed; fixed the joystick mapping in the CPC keyboard matrix; implemented more menu commands
Jun 30, 2001 - 22:57 settings stored in and retrieved from the registry; updated emulator_init and emulator_shutdown; file selector remembers path and selected file
Jul 01, 2001 - 17:54 ROM slot cofiguration is stored in and retrieved from the registry; automatically loads last DSK images on startup
Jul 04, 2001 - 00:34 colour tables for 16bpp (555 & 565) and 8bpp PC video modes; DDraw init updated with bit depth dependant code
Jul 04, 2001 - 22:06 fixed 16bpp colour tables; updated VDU screen centering code to work with all bit depths
Jul 06, 2001 - 00:35 implemented pause option; emulation is halted when application becomes inactive
Jul 06, 2001 - 19:34 zip decompression for DSK and SNA loading
Jul 07, 2001 - 00:58 fixed setting of GA colour table in load_snapshot; last DSK image load on startup supports ZIP files
Jul 18, 2001 - 18:40 DirectSound init code finally works correctly!
Jul 20, 2001 - 18:17 found the problem with the sound emulation: snd_multiplier calculation was done with integer arithmetic! grrrr...
Jul 25, 2001 - 00:48 *finally* got a clean sound code that won't break up anymore!
Aug 01, 2001 - 17:38 sound configuration is pulled from and stored in the registry
Aug 02, 2001 - 18:31 floppy drive LED is now shown on the CPC screen during data transfers
Aug 03, 2001 - 19:26 added About box
Aug 03, 2001 - 23:49 altered load_dsk() to allocate memory on a track by track basis (in preparation of fdc_writeID() support)

Aug 10, 2001 - 19:10 finished the General Options property sheet
Aug 11, 2001 - 17:29 up to 576KB of RAM supported
Aug 12, 2001 - 21:43 extracted psg_reg_write() from the psg_write #define; fixed the PSG setup in load_snapshot()
Aug 16, 2001 - 00:49 load_snapshot() now adjusts RAM size, and loads the correct CPC ROM as necessary
Aug 20, 2001 - 00:59 added save_snapshot(); header contains preliminary v3 info
Aug 20, 2001 - 16:10 updated load_snapshot() with processing of the 'official' v3 info
Aug 22, 2001 - 23:26 added Audio Options property sheet to control PSG emulation
Oct 06, 2001 - 13:22 removed the "experimental" joystick 2 support from the action map code - did not work as expected
Oct 07, 2001 - 20:27 added the save_dsk() routine
Oct 13, 2001 - 18:51 completed rewrite of zip handling; users can now choose images from multiple file archives
Nov 08, 2001 - 19:08 bug fix: the zip_dir routine caused a crash if a zip archive would not open properly
Nov 09, 2001 - 00:04 the ROM loading routine now checks the validity of the image, and skips a possible 128 bytes header
May 09, 2002 - 19:07 removed the DDSCAPS_3DDEVICE flag from the InitDirectDraw code; modified UpdateBounds to prevent strechblits

Mar 11, 2003 - 22:38 emulation can now continue to run when focus is lost; added more invalid object checks to ensure clean exits
Mar 12, 2003 - 18:08 had to add the background brush again: fullscreen mode would otherwise not update the unused area
Mar 12, 2003 - 19:02 added the 'auto-pause on loss of focus' feature to the Options dialog
Mar 12, 2003 - 22:07 added the display of HRESULT codes for DirectDraw function calls
Mar 17, 2003 - 22:40 added a check_drvX call to the eject disk menu functions

Mar 23, 2003 - 21:41 custom disk formats can now be specified in the config file; modified LoadConfiguration and SaveConfiguration to support this feature
Mar 29, 2003 - 16:40 tape motor is not turned on if there is no tape in the drive
Apr 02, 2003 - 21:31 changes to the Options dialog: moved the ROM slots to their own page; some cosmetic changes; remembers last page user was on
Apr 03, 2003 - 22:12 added the option to capture printer output to file; aborting a save dialog for a changed DSK now drops back to the emulation without taking any further action
Apr 07, 2003 - 19:09 modified the z80_OUT_handler to capture port writes for the MF2; added all the necessary bits for MF2 emulation, but for now it doesn't display the MF2 menu correctly (text is invisible!)...
Apr 07, 2003 - 21:59 doh! fixed the MF2 problem: the MF2 page-out port always set RAM bank0 instead if checking if the lower ROM was active
Apr 09, 2003 - 15:49 MF2 ROM is now restored at every reset to ensure the ROM area has not been corrupted by memory writes
Apr 13, 2003 - 16:18 added code to display the logo in the About box with a transparent background
Apr 16, 2003 - 16:18 joystick emulation can be toggled on/off; keyboard control assignments now override regular CPC keyboard actions; all dialogs now feature the "Caprice32 - " string to make identification easier; ZIP selector shows ZIP file name
Apr 26, 2003 - 14:03 added CaptureScreenshot to save the screen contents to a PNG file
Apr 26, 2003 - 16:25 finished screen capture implementation: added file selector and path/file storage to config file
May 05, 2003 - 22:46 updated the Audio page in the Options dialog with controls to choose the sample size and adjust the volume
May 06, 2003 - 18:59 load_snapshot and save_snapshot now use the v3 PSG information + the printer port data
May 13, 2003 - 17:41 fixed the file selector problem on drag and drop: the exit condition check was reversed
May 18, 2003 - 01:01 moved Gate Array memory handling to ga_memory_manager; save_snapshot correctly stores current RAM bank now
May 21, 2003 - 00:31 changed the colour palette generation to support an intensity level slider
May 21, 2003 - 14:42 added the Intensity slider control to the Video options
May 26, 2003 - 20:06 emulation loop needs to keep running to produce proper key events: fixes the Pause problem
May 28, 2003 - 13:59 modified the shadow of the print routine to make it more readable on a white background
May 29, 2003 - 15:09 implemented the info message display system and added strings for most emulator actions and keyboard shortcuts
May 30, 2003 - 12:17 added the tape PLAY/STOP button control for proper tape operation
Jun 02, 2003 - 15:05 if the CreateSurface call fails with video memory, it now attempts to allocate it in system memory
Jun 04, 2003 - 19:38 added the 'on printer port' drop-down to the Audio options page
Aug 10, 2003 - 14:35 z80_IN_handler: CRTC write only registers return 0; load_snapshot: fixed broken snapshot support (PPI values were written to the wrong ports!); digiblaster/soundplayer combined into one - changed from a drop down to a check box
May 19, 2004 - 23:13 removed all DirectX/Windows specific parts and replaced them (wherever possible) with the SDL equivalent
May 23, 2004 - 17:48 dropped double buffer scheme in favour of a back buffer/custom blit operation; fixed colour palette init in 8bpp mode; added support for half size render mode; back buffer is cleared in video_init(); replaced the SDL_Flip operation with an SDL_BlitSurface; initial ExitCondition is now EC_FRAME_COMPLETE to ensure we have a valid video memory pointer to start with
May 24, 2004 - 00:49 reintroduced snapshot_load & snapshot_save; modified vdu_init to update the two SDL_Rect structures to center or crop the CPC screen; introduced the dwXScale var to support the half size render mode
May 29, 2004 - 18:09 reintroduced tape_eject, tape_insert and tape_insert_voc; added sound support via the native SDL audio routines
