  value


Emu28 v1.03

EMU28.RC
- changed version
- changed IDC_DEBUG_MEM from static to listbox control, looks better
  in connection with WinXP style

  size of temporary buffer to size of destination buffer and fixed
  memory allocation bug in UNICODE mode
- changed function LoadBitmapFile(), it's better to validate the
  pbyRom instead of the hRomFile variable to check if the ROM is
  loaded to avoid possible side effects (ROM loaded by resource) and
  removed uncalled code part

KML.C
- bugfix in function KMLLogProc(), uncompleted wParam argument
  decoding in WM_COMMAND case and update of the bAlwaysDisplayLog
  variable only in the IDOK and IDCANCEL case
- bugfix in function ChooseKMLProc(), uncompleted wParam argument
  decoding in WM_COMMAND case and added UNREFERENCED_PARAMETER
  statement
- bugfix in function ParseLines() and ParseBlocks(), fixed problem
  of uninitialized variable which may occur on parsing corrupt KML
  files


Emu28 v1.02

  cycles counter in debug mode
- added implementation of "Profiler" dialog box

DEBUGGER.H
- extern declaration of global function

EMU28.C
- changed function WinMain(), added non modal "Profiler" dialog box
  in main message handler

EMU28.H
- extern declaration of global variable
- changed prototype of function AdjKeySpeed()

EMU28.RC
- changed version and copyright
- bugfixes in dialogs, some WS_EX_ styles (especially window
  borders) don't worked on some operating systems
- added Menuitem Info "Profiler..." in debugger menu
- added "Profiler" dialog

ENGINE.C
- bugfix in function Debugger(), fixed problem at quitting debugger
  when last executed opcode was SHUTDN
- changed function Debugger(), added call for 64 bit cpu cycle
  counter adjust
- changed function AdjKeySpeed(), changed back to v1.00 version,
  slow down on every key pressed

KEYBOARD.C
- changed function KeyboardEvent(), changed call of AdjKeySpeed()

KML.C
- changed function DrawAnnunciator(), changed making of gray scale
  mask

RESOURCE.H
- added definitions

TIMER.C
- bugfix in accurate timer handling, variable wasn't initialized so
  it might haven't worked


Emu28 v1.01

DEBUGGER.C
- bugfix in function Debugger(), removed illegal call of
  DestroyMenu() in WM_DESTROY message handler

DISPLAY.C
- changed function UpdateAnnunciators(), added gray scale emulation
  of annunciators

EMU28.C
- changed function OnCreate(), don't enable DragAcceptFiles() here
- changed function OnDropFiles(), checking calculator model to
  disable stack writing isn't necessary any more

EMU28.H
- changed prototype of function AdjKeySpeed()

EMU28.RC
- changed version and copyright

ENGINE.C
- changed function AdjKeySpeed(), a detected pressed key is now a
  boolean argument from caller; this allows to detect a pressed, but
  not by KBD_OR selected key -> no CPU slow down in this case

FILES.C
- removed unused variables
- changed functions CrcRom(), MapRom() and UnmapRom(), can handle
  packed ROM files now

KEYBOARD.C
- bugfix in function KeyboardEvent(), CPU slow down by calling the
  function AdjKeySpeed() on key pressed must be activated here

KML.C
- changed function DrawAnnunciator(), added gray scale emulation of
  annunciators
- changed function InitKML(), enable object "Drag and Drop"
  calculator model dependend here now

KML.H
- changed prototype of function DrawAnnunciator()

  detection
- changed function WriteIO(), added annunciators update in CONTRAST
  register (0x301, 0x302) emulation
