  don't check for interrupts after setting
- bugfix in function SetT2(), don't check for interrupts after
  setting

Service Pack 1 for Emu48 Version 1.0

DISPLAY.C
- red and blue has been changed in SetLcdColor()
- use display contrast value from chipset and not the default
  value in CreateLcdBitmap()
- use semaphores to avoid GDI trouble with NT in
  UpdateMainDisplay(), UpdateMenuDisplay(), WriteToMainDisplay()
  and WriteToMenuDisplay()
- execute ResizeWindow() only if window exist
- bugfix in draw part of WriteToMainDisplay()

EMU48.C
- version changed
- added global variable
- added semaphore handling to avoid GDI trouble with NT that prevent
  graphic update sometimes
- added message for right mouse key
- bugfix of a parameter of GetPrivateProfileString()
- removed SwitchToState() and KillKML() at end of program
- eliminated memory leak caused by SetWindowTitle()
- function OnPaint() may returned without calling EndPaint()
- execute UpdateWindowStatus() only if window exist

EMU48.H
- extern declaration of global variable
- added VOID as parameter in function prototypes

EMU48.RC
- added/changed version and copyright

EXTERNAL.C
- bugfix, check if beeper enabled
- changed beeper emulation, more realistic with Windows NT

FILES.C
- avoid an open handle and adjust file attributes in
  LoadBitmapFile()
- the WORD to int conversion used in function SetWindowPos()
  failed; windows with negative position data wouldn't pop up with
  NT (NT GDI is 32 bit coded, Windows 95 mostly 16 bit -> the
  failed conversion doesn't matter with Windows 95)
- bugfix in close file handling of function OpenDocument()
- InitKML() need chipset for contrast setting in RestoreBackup()

- bugfix in A=IN and C=IN command to emulate a saturn bug, on real
  machines the assembler commands only work on an even address
- bugfix in all r=r+CON fs,n and r=r-CON fs,n opcodes to emulate a
  saturn bug, on real machines commands with a single field selector
  cause an overrun to other fields of the register
- NFdbl() replaced by NFadd()
- Ndbl() replaced by Nadd()

OPS.H
- NFinc() definition changed
- NFdec() definition changed
- NFdbl() definition removed
- Ndbl() function removed
- changed implementation of Ninc(), added offset variable
- changed implementation of Ndec(), added offset variable
- optimized implementation of Nadd()

- added global variables, defines and constants
- added function SetAccesstime() for setting the correct time
- bugfix in AbortT2() which prevent updating the clock sometime
- changed implementation of CheckT1() to correct blink frequency
  of input cursor
- changed implementation of ReadT2() using a high resolution
  timer to minimize skipping timer2 values
- bugfix in SetT2(), always check timer2 control register
- solved a problem with timer2 counts greater than 16.67 min.
- bugfix of wrong timer1/2 values (unsynchronized threads)
