Lisa Emulator Change History http://lisaem.sunder.net/
------------------------------------------------------------------------------

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
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.
