           - imagewriter page size tweaking

2007.11.18 - found way to make graphics smoother, added menu options to 
             throttle menu to define balance between animation and CPU time.

--- 1.2.2 Release

2007.11.08 - fixed slot preferences - browse buttons between high/low ports
             were swapped.

           - fixed parallel port u/l assignments - opposite from what LOS uses

2007.11.02 - more via6522.c cleanup/fixes.

2007.10.18 - Renamed Profile menu to Parallel Port as it's more accurate

2007.10.15 - cleaning up Generator code so as to build it as its own library

2007.10.01 - looking into cleaning up unicode incompatibility bugs, rewrote
             bunches and bunches of string routines and fixed up some idiotic
             char * <-> wxString gymnastics.

2007.09.25 - Looking into via6522 bugs for MacWorks and Xenix, 
             no luck there yet

2007.09.19 - fixed romless floppy boot to always boot from floppy and not
             switch to Profile.

2007.09.15 - debugging ROMless boot.
             new bug: when trying to boot from floppy, if a profile exists
             and is bootable, LOS starts up from the Profile instead of the
             floppy.

2007.09.09 - David Cecchin's XPM icon in unix

2007.09.07 - added Save/Load PRAM to Preferences

2007.08.06 - individual profile power controls + create new profile inside
             a new menu named profile.

2007.07.28 - replaced all exit() and EXIT() calls with messages before
             quitting emulator so at least we know what crashed.

2007.07.27 - ROMless works with both profile and floppy now.

           - Fixed a bug with configuration saving.

2007.07.26 - Tracelog checkmark correction

2007.07.05 - LisaConfig bugs found - overwriting date information with
             garbage on save of preferences.

           - corrected a bug preventing the grabbing of the host time and
             date.  Found that MacWorks locks up when date is invalid.

2007.07.04 - LisaEm documentation completion

2007.07.03 - Testing various opcodes to locate scroll bar arrow bug in LOS
	     not found, but eliminated shift/rotate opcodes.

2007.06.29 - fixed inability to detect no-floppy from Lisa boot ROM
           - fixed entry to Service mode - not perfect, need to attempt 
	     to boot from bad profile.
	   - fixed tracelog bugs (hardcoded /log/lisaem-output)

--- RC2 
2007.06.26 - fixes to build.sh for differences between platforms.

2007.06.22 - floppy de-serialization routines.

2007.06.20 - rawbmp.h code finally works - except crashes on win32. :-(

2007.06.13 - rawbmp.h code works, much, much faster!

2007.06.12 - wxImage::SetRGB works - faster than old blit code

2007.05.01 - integrating new wxui code is taking me too long becaue of a lack
             of free time, so I'm going to go the other way so as to be able
	     to make a release soon.

2007.04.24 - Dual Parallel ROM cheat

2007.04.15 - Found OS X display slowdown issues
	
	   - Fixed display sizing issues when skinless.

2007.04.14 - Fixed skins on/off switch on OS X

2007.04.13 - Debugging video system on OS X

2007.04.11 - Added Disk Copy 6.x detection to libdc42 open.  This allows
	     better error messages to be returned.

2007.04.10 - Added MacBinII stripper to libdc42 auto_open

2007.04.09 - finalized buffered raw keycodes to compensate for repeats

	   - decoupled the COPS 1/10th second timer from Lisa CPU and tied
	     it to the host clock, clock is now accurate regardless of CPU
	     speed.

2007.04.08 - added Unthrottled menu option for those who want to melt their
	     host computer. :-)

	   - added buffered raw keycodes to compensate for repeats.

2007.04.07 - bug with raw keycodes that prevents updates found and fixed.

2007.04.06 - Changes for OS X issues (might roll these back since Jerome
	     Vernet found that the slowdown issues go away with wxWidgets
	     2.7.2, will test on all platforms before committing to either
	     path.)
		- reworked display to draw directly to dc and skip full blit
		  only done for AntiAlias mode, need to redo for all others.
		- reworked timing loop to no longer need wxMilliSleep

--------- RC 1 2007.04.04 

2007.04.04 - fixes to initial video position on skinless mode.

	   - added 8Hz display refresh rate for slow hosts.

	   - on shutdown throttle is removed + display refresh forced to 8Hz
	     to compensate for ~Imagewriter slowdowns.

2007.04.02 - changes to build.sh to incorporate version #'s via #define
	     and also modify Info.plist and _private.res inclusion on
	     OS X and Win32.

2007.04.01 - Added Reset button

	   - messing around with the VIA timing in hopes of fixing the
	     extra-fast clock.  Helps, but still a bit too fast.

	   - fixing OS X issues

		   - switching skins is really broken on OS X, so switched it
	     	     to will be done next time you run LisaEm.  This sucks,
	     	     but it sucks less than having a broken display.

		   - Printing on OS X works, but sometimes locks up LisaEm
		     on shutdown.


	   - windows now save their positions and restore on next boot

2007.03.30 - more printer work

	   - timing correction: catch up on lost cycles if cpu<clock

2007.03.28 - some light via work - attempting to fix any discrepancies
	     between via1/via2 (cops.c also contains via1_[i|o]ra().

2007.03.27 - printer work: changed printer wire plots to be rounder.
	   	           got rid of horizontal gaps, but it turns out
			   that there are protocol errors which cause two
			   more bugs: pages are pre-maturely FF'ed, and
			   horizontal data lines are lost on some lines.

2007.03.26 - with skins off, blacken whole screen instead to prevent artifacts
	     except for OS X.

	   - added option to completely hide the host mouse cursor.  It 
	     surprisingly works better than I expected.

	   - added Flush Printers menu item to force printouts to end
	     once they're done.  Should also speed up shutdown since this
	     happens there too.

2007.03.24 - James Savage of the Retro Mac Cast found these two bugs:

	 	- saving PNG screenshots are always grayscale.  Should be
		  color for full screenshots.

		- power button on skin is triggered by just moving the
		  mouse over the power button.  Fixed so click is required.

	   - fixed some issues with switching between skins on/off.

2007.03.20 - pauses reported by Kallikak fixed, throttle mechanism rewritten

	   - printing: added scale as some printerDC's are 600dpi and we
	     work at 300dpi.

2007.03.18 - printing: fixing half page issues

	   - fixed memory clobbering bug in printing code - caused profile
	     corruption on linux since dc42's are mmap'ed, would have caused
	     random issues elsewhere.

2007.03.17 - printing: fixed png background color issue

	   - printing: pages were halved vertically, fixing this now but
	               not quite right yet, only half a page makes it out
	               now but it is the correct aspect ratio. 

2007.03.16 - added Refresh Rate to display menu: 60,20,12Hz. (Needs to be
	     in odd multiplier of refresh rate, otherwise cursor in text
	     fields will stop flashing)

	   - Printing: tweaking color table in BMP generation as PNG's show 
	     up with a gray background. (BMP's show up properly.)

2007.03.15 - fixed mouse/skin issues.

	   - fixed some serial port issues, but still crashes emulator.   

2007.03.14 - skins initialization issues with skins on. caused mouse issues
	     on startup.

	   - skinless size increased as edges were getting cut off.

	   - some z8530 fixes, but still does not properly work, causes LisaEm
	     to quit.


------------------------------------------------------------------------------
2007.03.13 - found a fixed config bug: serial b options copied from port a.

	   - added a switch to turn off power to the virtual Profile before
	     power on.  This allows you to prevent the boot ROM's Power on
	     self test to automatically boot from the Profile.  It's useful
	     when you need to repair the Profile since it allows you to
	     boot from "Lisa Office System 1/5" and then power on the
	     Profile drive to repair the file system.

2007.03.11 - Proper BMP's are now generated for printing, conversion to PNG
	     format works, but is a little bit off - background is gray,
	     should be white as in paper white.

	   - added command line ability to load preferences file when
	     launching. i.e. ./lisaem ~ray/macworks.lisaem will open the
	     macworks.lisaem preferences file from user ray's home.

2007.03.10 - getting closer on proper BMP generation for printing
	
	   - added throttle setting to global preferences.
	
	   - added ROM checksum failure warning on power on.  If the ROM is 
	     broken, it can crash the emulator. 

2007.03.09 - skins on/off added to Display menu.

	   - found IW linefeed pixel bug (lack of initialization)

2007.03.08 - video modes are a bit smarter - if display size is too small, 
             will refuse to change video modes and will instead switch to 
             lower mode, or shut off skins.

	   - re-enaled 2Y and 2X3Y video modes (skinless of course.) with 
             checks for display size.

	   - skin/less mode switch no longer requires restart of emulator.  
             Extra space past display region is blackened to ameliorate window
             sizing bugs.

	   - Preferences "Apply" button (was save in preview versions) closes
             Preferences window.


2007.03.06 - added skinless option (bug: size of window is too small/off). One 
             blit less during skinless mode so it's a bit faster on older 
             machines.

	   - NMI key can be forced now.


2007.03.02 - Video mode, sound effects, asciikeyboard as globally saved prefs.

	   - added Sound Effects checkbox.

	   - debugging printing - somehow all pages show up black.


2007.03.01 - added NMI key to keyboard menu.


2007.02.28 - new IW code printouts sort of works.


2007.02.21 - Added Preferences panel for printer settings.


2007.02.20 - added size dialog box when creating profile (5/10MB, etc)


2007.02.18 - unified build.sh


2007.02.05 - I/O ROM version was getting clobbered by code in floppy.c to 
             0xA8 via a #define.


2007.02.03 - cheat_ram_test now a preference.

           - if starting without ROM, dialogbox is shown, then preferences are
             shown asking for config.

	   - bug fix: after closing preferences, re-opening caused segfault.

	   - finer speed control - much closer.
	

2007.02.02 - fixed floppy insert on power off

	   - fixed floppy trapping on insert of non-DC42/bad disk image.

	   - fixed "Clock is not set" dialog box

 	   - fixed ContrastTrails (linx/win32)


2007.02.01 - fixed raw kb entry - but CPU clock is still too fast.


2007.01.31 - fixed bug causing random crashes, mostly during LOS install.  Was
             off-by-one array overflow related to ReDraw_* fn's.


2007/01/28 Preview Release 2
============================

Fixes:
* Fixes to libdc42 for profile access. Should be able to read and write to
  ProFile images to install Lisa Office System on a new disc.

* Split ROM images are now supported - it will automatically merge them and
  save as *.ROM

* Double-clicking on the mouse is now recognised in Lisa OS. This fix is a
  hack, and will need to be fixed properly in the future.

* When quitting LisaEm on Mac OS X, the Preview Release used to crash. This
  has been fixed.

* Crash on Restart from Lisa Office System Installer fixed.

* Missing horizontal scrollbar on OS X seems to be fixed, but not sure why or
  how.

* The duration of the click sound during the Lisa ROM tests was far too long,
  it now clicks rather than beeping.

Known bugs:
* Floppy animation does not work on OS X due to double buffering.

* Floppy motor sounds and some other sounds do not work on OS X

* Some light gray screen artifacts in the Windows build.

* Still no documentation at all.


2007/01/24 Preview Release
