5c38c04fb4 - fixed possible segmentation fault in parse_line_formatted(): cause a PARSE_ERR 
if a bochsrc option comes without a parameter.
- comment handling in parse_line_formatted() no longer needed

3411535a8b - 'split screen' feature for standard VGA 16-color modes implemented 
* new variables 'line_compare' and 'vertical_display_end' depend on CRT
    register values
  * implemented 'split screen' in functions update() and mem_write()
- mem_write(): CGA section: unnecessary variable 'isEven' removed

8b22768895 - applied some speed optimizations in mem_write() from patch.vga-mode2-speed-dohzono 2003-05-01 12:07:27 +00:00

d02c729791 - removed variable 'scan_bits' and added new variable 'line_offset'. It specifies 
the address offset between two lines on the screen in all VGA modes.
  It depends on the CRTC offset register value and the address mode (byte, word,
  dword)
- moved screen update code to the end of the write handler. If a register change
  should force a redraw of the screen, the variable 'needs_update' must be set
  to 1.
- changes to the attribute controller palette index register now force a redraw
  of the screen
- modeX: calculation of the tile numbers fixed

b1324da2e1 - function mem_read() rewritten 
* check memory mapping before everything else
  * read mode 1 optimized using a part of patch.vga-mode2-speed-dohzono
- function mem_write(): check memory mapping before everything else
- writes to the CRT registers are handled only if the new value differs
- a CRT start address change forces a redraw of the screen

e79aa992af - emulated CGA graphics mode 160x100x16 colors implemented using the text mode 
with 100 rows and a char height of 4
- raster operations AND, OR and XOR in write mode 2 implemented (part of patch #707931)
- use the vga_tile_updated array in modeX like other modes do
- small optimizations in the graphics update code

a6dd6deaf5 - apply patch from James E. Flemer: 
I've got a game that uses OPL2 functions.  It's still not
working yet, but this patch brings it closer.  Using Jeffrey S.
Lee's "Programming the AdLib/Sound Blaster FM Music Chips (Ver
2.0)"[1] as a reference, I found an inversion of the OPL timer
masks in the sb16 code.  Without this patch, the emulator uses
the wrong bits for masking, and completely botches the flags
register (note the bitwise AND vs OR).

daee2aac9b - improvements to mode 13h emulation (start address, scan bits, doublescan, 
double width)
- cleanup in modeX emulation similar to mode 13h
- consider start address in function mem_write for VGA modes
- register 0x03c8 is readable, too

548dd3a13c - doublescan feature implemented (used by CGA 640x200x2, VGA 640x200 and modeX)

  switching to text mode, do the same when changing the palette or disable video
- simplified the function determine_screen_dimensions()
- fixed the code for the CGA mode 640x200x2 in update() and mem_write()

626858a4bd - Stanislav asked me to remove this, for these reasons: 
1) It has a bug which is already fixed in the main trunk
  2) Its code was already committed to the main trunk
