In Memory map view:

Memory map shows current values of memory cells. Ctrl+M switches bank to
RAM. Each memory cell value is mapped into RGB or Gray or None. In RGB mode 
red are values from 0 to 85, green are values from 85 to 170 and blue are 
values from 170 to 255. In Gray mode all values are mapped into grayscale
colors.

Memory access:
  white shows current PC
  blue  marks read access
  red   marks write access

You can change colours to ICU-standard (read marked by green) in Settings.

You can Mouse Click inside memory map to scroll data dump view to a clicked 
memory address. You can double Mouse Click to scroll disassemble view to a 
memory address under cursor. You can Ctrl+Mouse Click to scroll Disassembly 
to code address that stored value under cursor.

You can zoom-in using mouse wheel and move around by holding right mouse click
(Windows, Linux, MacOS) or use mulitouch gestures such as pinch zoom and 
scroll using two fingers (MacOS only). You can select desired control behaviour 
in Settings.


In Breakpoints screen:

Arrow keys
	Move around
Enter or Spacebar
	Toggle value or start editing breakpoint


* Commodore 64 screen

All keys are mapped as original Commodore 64 keyboard. RUN+STOP is mapped to
ESC key. Left Control key is not mapped and reserved for keyboard shortcuts. 
Right Control is mapped into C64 Control key. RESTORE is not mapped, but you can change 
this in Settings. 

When joystick is turned on then you can control selected ports using arrow keys,
and right-alt as fire.


* Atari XL/XE screen

Additional keys in Atari:

F2
	Option key
F3
	Select key
F4
	Start key
	

* VIC state view

This view shows state of VIC registers. You can lock colors using Mouse Left Click,
or change them using Mouse Right Click, these will be reflected in previews like
Memory Dump or VIC Display view.


* SID state view

You can click waveforms to mute SID channels. Detected musical notes are
displayed, these are based on standard 440Hz A4 notation.


Note:
You can click inside VIC/SID/CIA/VIA state views to show values of registers. You can 
edit these values by clicking on value.


* VIC Display screen:

The VIC Display screen is like an X-Ray for the VIC chip. Whole frame is recorded
and you can access state of VIC and CPU for each cycle of the frame. It can 
be activated by Ctrl+Shift+F5. VIC Display renders exact state of VIC for 
selected cycle. As you know, a lot of effects are using tricks of the VIC chip, 
so it will not show the C64 screen in its entirety, as it is not meant to. 
It will always show a screen how it would be rendered for selected cycle of 
the VIC chip.

You can just move mouse cursor over the VIC Display frame and see how VIC
registers impact rendering of the C64 screen. Note that status of CPU registers
and VIC state view is marked in light-red color background, this is to indicate
that state is locked and shows selected raster cycle. The disassembly code is moved to 
the place where raster beam was executing code in the frame. Space bar changes 
disassembly code lock. Also, when you move the cursor over VIC Display, the memory dump
view cursor points to address which is under mouse cursor.

When you click on the VIC Display you can lock cursor and then move it with keyboard 
arrow keys, holding Shift will increase the step. You can unlock the cursor by pressing
Space Bar or by Mouse-Clicking on locked cursor.

There are buttons to control the VIC Display, you can see what are current values 
of VIC bank, screen, bitmap etc. and you can force and change them by clicking on 
values: green color means it is a current state for selected cycle, red is when you 
forced the selection. Do not forget, that if you select something making it red, then 
the VIC Display will show your selection, not what is currently going on on the screen.

Button "Scroll" will switch if VIC scroll register should be applied to VIC Display 
position. When code is opening side borders then applying the scroll register may make
the display jump a lot, so you can select if you need this behaviour.

Button "Bad Line" shows a bad line condition when text is red, switching it on will 
display lines that are in bad line condition.  

Button "Border" changes if side border should be shown. It has three states: no border,
viewable area with border, full frame scan.

Button "Grid" changes if a grid should be displayed.

Button "Sprites" changes if sprites graphics should be rendered in the VIC Display.

Button "Frames" changes if frames around sprites should be visible.

Button "Break" adds VIC raster breakpoint, the text is in red when a selected line has 
already the breakpoint set.

The "Show PC for" informs in which auto-scroll code disassembly mode we are, you can 
click on the mode and change it to other mode (Raster / Screen / Bitmap / Colour / Charset).

VIC Display records state of VIC each cycle in the frame and with the mouse cursor you
can see what is in the frame. The X key changes what we "look" at: where was the code 
in a given cycle (Raster mode) or where the code saved the pixel in memory (Raster / 
Screen / Bitmap / Colour / Charset). For Screen / Bitmap / Colour modes the memory
view cursor under C64 screen will be moved to address that holds the value at cursor. 
For Charset mode the memory view cursor will point to a charset and definition of char
under cursor.  

You can Right-Click on C64 Screen in right top to replace it to a zoomed raster view. 

Keys that you can use in this view are:

Arrow keys
	Move locked cursor
Shift+Arrow keys
	Move locked cursor in large steps
` (~ tilde key)
	Toggle VIC raster breakpoint
L
	Lock/Unlock mouse cursor
Space Bar
	Lock/Unlock Disassemble auto-scroll code
X
	Select next auto-scroll code mode
R
	Select auto-scroll code to Raster
S
	Select auto-scroll code to Screen (Text)
B
	Select auto-scroll code to Bitmap
C
	Select auto-scroll code to Colour


* VIC Editor screen

The VIC Editor screen is for displaying and editing graphics in real time. All painting
is done in a live C64 emulation and is immediately reflected in C64 RAM and VIC chip.

Layers window shows available layers, default layers are:
- Unrestricted: you can paint on this layer in so-called hires unrestricted mode, thus 
  using C64 colors without any limits
- Sprites: this layer is used for painting on all visible sprites in this frame. These 
  are virtual sprites, so in particular de-multiplexed sprites. Note, that displaying 
  of virtual sprites from this layer is not implemented yet, thus the "V" button changes 
  only if you can paint on this layer. However, you can see these sprites as they are 
  rendered in the C64 Screen, so actually you can paint on them and see changes.
- C64 Sprites: these are sprites that are in a raster line under cursor, just the same
  like in VIC Display view.
- Display: this is the same VIC Display which works exactly the same way, thus exact 
  state of VIC for selected cycle under cursor is rendered.
- Reference: this works like Unrestricted but has full palette and images imported 
  into that layer are displayed as-is. Painting on that layer is disabled by default,
  you can paint only when this layer is selected.
- C64 Screen: this is the C64 Screen as it was rendered by VIC, note that if emulation 
  is paused, then painting on this layer will not have immediate affect - the VIC must 
  render the screen first to have changes visible.
	
There are “V” buttons near layers names, these set visibility of the layer. 

You can select the layer by clicking on it:
When layer is selected, all painting is done on that selected layer, even if it is 
not visible. 
When no layer is selected, then painting is made from top-to-bottom, it is driven to 
a layer that has higher priority first, that is visible and has a pixel under 
selected x/y mouse position which is inside that layer (for example if there are no 
sprites under mouse cursor, then sprites layer will be skipped and painting will be 
done on C64 bitmap).

Painting depends on selected mode. In all modes you are free to paint, however if you 
exceed available number of colors the painting will be blocked. To un-block and force
color replace you can hold Ctrl key  (this can be configured in Settings). 

The replacement color will be selected and it will be replaced: 
- in Hires Bitmap this will be color under cursor in 8x8 char,
- in Multi-Color Bitmap this will be color that is less-used in 8x8 char (has least 
  number of pixels),
- on Sprite this will always be individual sprite color ($D027+).

Painting with RMB On Sprite will always use background color ($D021).

You can paint in dither mode by holding Alt key: pixel colors are alternating between 
LMB and RMB. When you paint first pixel, a dithering grid will be created, and by 
holding Alt key this grid will be used for painting. The dithering grid will be reset 
when you release the Alt key.

Sprite window shows current selected sprite. You can lock selected sprite by clicking 
mouse on sprite with Ctrl+Shift. Then you can select color to use for paiting by clicking 
on the color in Sprite window or by pressing (0, Shift+1, Shift+2, Shift+3). 
To change locked color just select a new color from palette, this will replace 
the color of locked Sprite. Note that $D021, $D025 and $D026 are shared with other 
sprites. If you not select color in Sprite window, then painting on Sprite will try 
to use selected color from the Palette, if color is not in available colors then the
painting will be blocked and to un-block and force color replace use the Ctrl key.

You can change multicolor, horizontal or vertical stretch by clicking buttons.

You can change positions of Sprites the same way, just lock/select a Sprite
by pressing Ctrl+Shift+Mouse Click on that sprite, and then use Arrow Keys
to move that selected sprite (Arrow Key Left/Right/Up/Down).

Note, that changing colors, positions and settings of Sprites is quasi-intelligent: 
in current frame's code that was run, places of LDA/LDX/LDY and STA/STX/STY pairs 
are found for sprite colors or positions and values of LDA's are replaced based on 
current raster position. Thus, you can write your own display and colors multiplexer 
code, run it and when you change colors of sprites the code in C64 RAM will be replaced 
accordingly, even if you use Sprite multiplexing.

Charset window shows current charset, you can select char and use it for painting in
text modes.

It is possible to import PNG and convert it to current mode, hires/multicolor bitmap
and hires text modes are supported. PNG must have resolution of 320x200 or 384x272. 
Colors are matched to nearest C64 colors (nearest neighbour). For bitmap modes colors
in 8x8 are set based on most used color values in 8x8, thus first a color that has
largest number of occurrences in 8x8 char is found and it is replaced for converting
in that 8x8 char, then in multicolor the another one, etc. If sprites are present in 
the screen, colors are matched to colors selected in the sprite and pixels are converted, 
note that no automatic color replacing is possible at this moment. The 384x272 resolution 
includes also borders, so if you have sprites in side border the pixels will be 
converted accordingly.

Note, that a workflow with sprites is that you should have some init PRG procedure that
sets position of sprites. The converter is quasi-intelligent, thus is trying to find
places of LDA/STA for colors in the current frame. 

You can also import KLA (Bitmap Multi-Color), ART (Bitmap Hires), DD (Bitmap Hires) and
export to KLA, ART or raw text depending on selected mode.

Note: when you export to raw text it contains these blocks:
$000-$3E7: Current character video memory (screen). For example values stored in $0400-$07E7.
$3E7-$7CE: Color memory (values stored in $D800-$DBE7)
$7CF:      Background color (value stored in $D021)

Zooming and panning of the canvas is performed using mouse, you can use Mouse Scroll
for zooming and hold Space Bar for panning. Also, you can Mouse Right-Click on Preview
Window to quickly move the painting area to selected position. When you zoom-in deeply
then numbers such as pixel addresses and values will be also shown.

* Breakpoints screen

Breakpoint stops the execution of code depending on some state and situation.
In the Breakpoints screen (Ctrl + B) you can click using mouse, or Enter or
Space key to enable or disable monitoring of selected type of the breakpoint.
New value can be added by selecting "...." either by moving the cursor with the 
arrow keys or clicking using mouse. 

These are possibilities:
  VIC / CIA / NMI - stops when selected interruption occurs
  CPU PC - the code will stop as the processor will start to perform instruction 
           from selected address
  MEMORY - stops when there will be attempt to write to the memory of the set 
           value, for example: 4FFF <= 3F will stop code when there will be 
           attempt to write to the cells 4FFF value less or equal to 3F. To
           break at any write access you can use <= FF
  RASTER - stops when raster reaches the set line value

Breakpoints CPU type PC can also be set in the disassembler view by clicking
the mouse cursor on the address or by pressing the ` (tilde) key.

The same applies to 1541 Drive breakpoints on right side of the screen.


* Breakpoints file

Breakpoints file stores information about breakpoints, addresses and values.
Possible entries are:
  break xxxx - break when PC reaches address xxxx
               Example: break 3FFF
  breakraster xxx - break when raster reaches line number xxx
               Example: breakraster 40
  breakmem xxxx oo yy - break on memory write to address xxxx when
               expression oo yy is true. Possible operators oo are: 
               ==, !=, <, <=, >, >=
               Example: breakmem D018<=FF
  breakvic - break on VIC interrupt
  breakcia - break on CIA interrupt
  breaknmi - break on NMI interrupt
  setbkg xxxx yy - fake marker, when PC reaches address xxxx then background 
                   colour register ($D020/$D021) is set to value yy, you can mix
                   this type of breakpoint with normal "break" to also stop code
                   execution

All entries are not case sensitive. Please check KickAssembler documentation, 
section 9.5: Writing to User Defined Files.

* Code labels (symbols)

You can load a symbols file wit code lables via -symbols <file> command line
option. Also, if near loaded PRG a file with "labels" file extension is found
then it is loaded automatically. Two file formats are accepted, a standard
Vice code labels format and 64Tass compatible file format.

Vice code labels file format example:
al C:d019 .vic2_int_reg

Note, that label name's leading dot is skipped.

64Tass labels file format example:
vic2_int_reg          = $D019


* Watches

Watches view is a simple way to display selected values in memory with a label.
You can replace the memory dump view by watches view with Ctrl+W key. The feature
is simple display of hex value stored in associated memory address, but this will
be expanded in future to allow also different data representations.

To add watches you can do that only via external file that you can load from 
a command line.

The format of file is simple, and there are two formats accepted.

Simple watches format example:
d019   vic2_int_reg

64Tass-labels compatible format example:
vic2_int_reg          = $D019

For example watches file please refer to:
https://sourceforge.net/p/c64-debugger/code/ci/master/tree/Examples/example.watch

<C64debugger/>


So everything is inside a <C64debugger> tag with a version number. Inside are different tags: 

There will always be one <Sources> tag with all the source files and their indexs.

There will be one or more <Segment> tags - one for each segment. Segments contains zero 
or more <Block> tags and inside these are the usual debug data. 

There will always be one <Breakpoints> tag. It contains one line for each 
breakpoint. First arg is the segment it is defined in (so if you turn on and off segments 
you can switch breakpoints on an off too). Second argument is the address it is defined at 
(You will not need it in eg. .break "nmi", but it is always there). 

Third argument is whatever the user writes in the .break argument and might be empty. 
So .break "nmi" and .break "cia" will give nmi and cia. 

<Labels> tag adds a label at address. First argument is the segment name, second argument is 
the address and last argument is label text.

<Watchpoints> is similar to labels but it will appear in watches view. First argument is 
the segment name, second argument is the address, then third argument is number of values 
to display, and fourth argument declares a representation which can be:
hex8, hex16, hex32, or simply h, h8, h16, h32 is hex representation of value interpreted as 8, 16 or 32 bits.
signed8, signed16, signed32, or simply s8, s16, s32 is a signed decimal representation of value interpreted as 8, 16 or 32 bits.
unsigned8, unsigned16, unsigned32 or simply u8, u16, u32 is an unsigned decimal representation of value interpreted as 8, 16 or 32 bits.
text signifies text representation.

Please note that representation and number of values are not yet displayed in Watches view, 
this will be updated in upcoming version. Now, the Watches view displays only one hex 8-bit value.

View to see disassembled code with the source code is available via the
Ctrl+Shift+F3 key. It will display the disassembled code on the left, and
source code on the right. On top near the disassemble you will see a segment
name and a block name below. To switch segments you can click on the segment
name or use keyboard shortcuts Ctrl+; or Ctrl+'


* Champ-6502 profiler

C64 Debugger allows to create a profile file that can be then used to create
profile reports in HTML format. This feature is still in development,
however it is usable. Note that profile labels, watches and screen dump are not
completed yet. Champ uses Ruby and GraphViz thus you need to install these
packages first. You have to run the C64-debugger compatible version
of Champ ruby source which is available to download from SourceForge C64 Debugger
project.

To start generating profile file go to Settings/Emulation and select file
path. The debugger will dump all profile data needed for the Champ in this
file, default file extension for profile data is *.pd 

When you finished running code that you want to profile next step is to
create profile report using command line:

$ c64d-champ.rb <file.pd>

Champ will create a report.html with report-files folder that you can view
using standard web browser.

The report log file consists of these types of events:
cpu <emulation cycle> <frame number> <previous PC> <register A> <register X> <register Y> <PC> <SP> <processor flags> <profile cpu cycles> <raster line> <raster cycle> <is bad line>

vic <emulation cycle> <frame number> <raster line> <raster cycle> <is bad line> <is sprite dma> <raster irq line>

jsr 0x<hex addr> <cycles>

rts <cycles>

cycles <cycles>


* JukeBox playlist and automated tests

JukeBox playlist is a way to automate things in the C64 Debugger. The idea is that
you can write a JSON file in which actions and settings for the jukebox are set.
Examples of usage include:
- simply playing demos from a playlist, with fade out/fade in transitions, good for
the big screen!
- set warp speed on, load demo, set warp off, automatically press space on notes, 
  then dump memory in selected frames.
- load game, automatically move joystick, etc.

Note, that all timings selected are in seconds or milliseconds, but are re-calculated 
to VIC synchronization frames, so the timings will be always exact and synced to VIC
refresh. The frame number depends on selected system (PAL, NTSC). Calls to move on
with transitions, dumping memory and other actions are always synchronized to VIC and
are performed at end of each VIC frame.

You can use TheTom/Samar's site to create playlists:
http://tomseditor.com/gallery/playlist

JSON format is as follows:
1. All "global" settings, such as if fast boot kernal patch should be included.
2. Entries for each file load.
3. Each entry has its own settings (such as file path) and actions (such as key strokes,
   joystick movements, memory dumps, etc).

For example file please refer to:
https://sourceforge.net/p/c64-debugger/code/ci/master/tree/Examples/jukebox-win32.json

* Other notes

Step over JSR works in a way that a temporary PC breakpoint is created in
next line. Code will be stopped when PC hits that breakpoint address, in
most situations just after returing from JSR. Note that if code never 
returns from JSR this breakpoint will still be "valid".

You can also drag & drop file into C64 Debugger window on MacOS & Windows. Depending 
on selected option in Settings the file can be auto-started, also from disk image file.

You can browse the contents of attached disk image by pressing F7 key, and
run the first PRG by F3 key. Note that if C64 Screen is selected then these keys are 
normally sent to the C64. Thus to let these key shortcuts work you need to first 
un-select the C64 Screen.


* Note about Atari XL/XE

Atari XL/XE debugger is using Atari800 emulator. This integration is still 
in experimental version and a lot of features are not ready yet. There definitely 
are bugs and other issues, however main features should be working.


* Known bugs

When snapshot is loaded then selected settings are not updated in the Settings 
menu (such as SID type, C64 machine model, attached disks, etc).

Loading NTSC snapshot into PAL machine or vice-versa is not supported and will 
hard reset the C64. 

It is not possible to zoom Drive 1541 memory map.

Clicking Drive 1541 memory map does not properly set selected value in memory 
dump view.

Command line arguments are passed to VICE. VICE complains that arguments
that have been parsed by C64 Debugger are not OK.

On some window managers flavours in Linux system open/save file dialogs are
behaving incorrectly.

When you move a Sprite in VIC Editor and Sprite is on top of other Sprite they will 
'pile up', also there are no means to select Sprite below a Sprite... this is not
ready yet and is planned for next release.

Atari800 has troubles with saving and loading states when machine has more than 64kB
of RAM memory selected. This seems to be a bug in Atari800 3.1.0, still under 
investigation.


* To do

Add memory map zooming for Drive 1541.
Add working on files directly instead of C64 memory (file adapter is ready),
to view/edit files directly on disks.
Add custom layouts with layout editor.
Add PAL CRT emulation.
