stephena 8f68c677d4 Added commandline argument 'gfxformat', also accessible from a right
mouse button context menu in the disassembly listing.  This is used to
set the default display format for GFX data sections (currently, binary
and hex are supported).

Fixed bug in several debugger input areas to accept the '\' symbol.
This symbol is needed when entering data in binary format (it must
prefix the data if the default base for that field isn't binary).

Added 'jump' debugger prompt command, used to scroll the disassembly
to the given address (or there-abouts, if the address isn't valid).

Editing data in the disassembly now won't cause the display to jump to
the current PC.  The display will only move to the PC when it actually
changes.

stephena e0dd8b1451 First pass at extending the disassembler to support CODE/DATA/GFX commands
from a Distella config file.  For now, the commands are only accessible
within the debugger prompt, and can only be added (no removal/editing).

stephena f742f67788 Optimized Distella in the case of 2K ROMs. Now only half the
address space is shown (either $F000 - $F7FF or $F800 - $FFFF).
This eliminates a lot of .byte directives that are invalid in
2K mode anyway, and speeds up the disassembly a little.

stephena b2ed949082 Some final changes for the 3.2 release, including documentation updates.
Added 'ramrandom' commmandline argument, used to toggle randomizing or
zeroing or all RAM in the system (both zero-page and SARA).

Disassembler now properly supports all test cases, including rewinding
within the debugger.

Added preliminary support for disassembling from zero-page RAM.

Bumped version # for final release.

stephena d007c3502f Several big improvements to the debugger:
The disassembler now accepts a range of start addresses and remembers
old entry points, so the disassembly becomes more complete each time
the debugger is used.

Changes to address offsets within the same bank are now supported
(ie, changing from $fxxx to $dxxx within the same bank properly
updates the display).

Re-added ability to manually change banks from the debugger prompt
and the disassembly UI.  This now works correctly with the Distella
code.

Cleanup of the Cartridge::bank(...) API: if a bank cannot be changed,
the calling code will now know about it.  This fixes confusion with
some ROMs, whereby changing a bank in the debugger prompt would print
a success message even if the operation failed.

Note that these changes have broken rewind in the debugger.  Actually,
it only exposes problems that the rewind functionality already had :)

stephena 88f7f656e6 First pass at integrating dasm '.sym' labels into the disassembly output.
For now, only the infrastructure is being modified.

Make disassembly output a little nicer by drawing a vertical line
separating disassembly text from the actual raw bytes.

Some changes to the SDL sound code initialization, which will (hopefully)
eventually lead to a fix for those users with ATI video drivers, and
not having sound after the first game has been played.

stephena 0c1029076c First pass at making Distella aware of labels defined in a .sym file
or from the user.  Before this is done, the parser needs to recognize
variable-length labels (right now, it used fixed spacing and assumes
the largest label is 8 characters).

Fixed bug in Distella; a label was being printed with an incorrect
quote symbol, which would break parsing of that line.

stephena 2193c94b12 Updated boilerplate on top of each source file to include
'Stephen Anthony' (aka, me) in addition to Brad Mott as copyright
holders for Stella.  I think I've been with the project long
enough now (almost 10 years) to justify being specifically mentioned
above and beyond 'the Stella Team'.

stephena ea6ea9a7bd Renamed 'autocode' commandline argument and associated UI item
to 'resolvedata', since that more accurately describes what it does.
Also, it now accepts arguments as strings (never, always, auto)
instead of 0, 1, 2.

Updated main documentation for changes in OSX port 'basedir'.

Updated debugger documentation for recent command additions, and
provided new snapshots where the UI has changed.

It seems to be getting close to a new release - perhaps this
coming Friday.

stephena e536a9ee00 Some minor cleanups to the Distella class.
The debugger 'disasm' command now works again for addresses below
0x1000, and it also now correctly accepts the number of lines to
output in the disassembly.

stephena dc22bc6b04 Some cleanups to the RomListWidget. Long '.byte' lines no longer spill
over onto the opposite side of the screen.  Breakpoints set by clicking
in RomListWidget only apply if they've actually been enabled.  This
fixes a bug whereby a breakpoint could look like it is enabled when
it really isn't.  Related to this, breakpoints cannot be set for
disassembly lines that don't contain a valid address or an empty
bytes area (basically, empty lines and lines containing '.byte' items).

stephena 0ed4a9fa79 OK, I've finally gotten back to Stella development and fixing the
disassembler.  Hopefully this will lead to a new release very soon.

Added 'autocode' commandline argument and associated UI item (in the
RomWidget debugger area), which controls how Distella will use the
'automatic code determination' option.  If set to 0/never, this is
completely disabled.  If set to 1/always, it is always enabled.
The default is 2/automatic, whereby it is first turned on, and then
turned off if the disassembly doesn't contain the current PC address.

RomListWidget has now been completely reworked, so that it informs
RomWidget of its intent to change breakpoints and patch ROM.  If
either of these fail, the action won't be performed, and more
importantly, it won't appear onscreen as if the action has succeeded.
This fixes an old bug whereby patching could fail, yet the onscreen
ROM data was actually changed.  Related to this, the list has been
made as efficient as possible, and its contents are never un-necessarily
copied.  Also, lines in the disassembly that cannot be modified no
longer show an edit area.

Due to the way the new disassembly works, you can no longer switch between
banks in the RomWidget (Distella would probably fail to disassemble in
such as case).

EditTextWidget can now indicate its contents have changed when adding
text to it.

stephena e0310e8f35 Checking in WIP for Distella integration. Moved the internal text
handling to C++ stringstreams instead of C-style character arrays,
which fixed some segfaults (sprintf is evil).

First pass at tying the number of banks to the disassembly.  The idea
is that the startup bank (which is now identified by the cart) always
starts at address at 0xfffc, while the other banks are defined by the
PC at the first time we enter the debugger.  This is still a WIP,
since there's no actual checking done yet to see if the current PC
is in the current disassembly.

Added 'ctrlcombo' commandline argument, which completely disables
checking for Control-x key combos.  This is useful when playing
2-player games where the 'f', 'r' and 'Control' keys are supposed
to be treated separately.  Previously, pressing Control and 'r' or
'f' processed some other action (change framerate, reload rom, etc).

stephena 6de4e358e1 More changes to CartDebug. Labels read from a symbol list or defined on
the debugger commandline are now reflected in most parts of the debugger UI.
Still TODO is have DiStella use those labels in the disassembly, and deal
with the formatting issues this will entail.

Still completely broken are built-in functions, getting an equate address
based on label, and tab-completions.

stephena 8b22097cb6 Further improvements to read vs. write mode in the debugger for TIA
addresses.

Fixed a bug in processing accumulator-access opcodes in the debugger;
an uninitialized char array was causing a segfault.

stephena a150ece7ae Updated DiStella disassembly to differentiate between the intent of an
instruction (read vs. write) for those addresses that have different
meanings based on how they're accessed.  For now (and probably forever),
this only affects TIA addresses.

These ideas were ported from the old Stella disassembler.  Perhaps they
should be ported to distella as well, since it makes for more accurate
results.

stephena 8ca34a4d90 Checking in WIP for DiStella integration. The disassembly is now shown in
the RomListWidget instead of being printed to the terminal.  There are still
graphical glitches with this, but for a first pass, it's nice to see actual
Distella output in Stella.

Partially working 'disasm' command from the PromptWidget.  Currently, it
only disassembles cart address space (aka, 0x1000 or above).

Removed the old disassembly code from CartDebug.  Still TODO is fix the
label stuff, both in getting DiStella to use it, and adding/removing
labels.  This is greatly reduced now that we only have to worry about
user labels.

stephena 03191759ab More DiStella cleanups; the disassembly now properly uses peek() and dpeek()
methods from Debugger directly.  As well, the start address is now passed
into DiStella::disassemble() directly; decision to start from the reset
vector is done outside DiStella.  This is in preparation for starting
the disassembly from any valid address.

stephena deedb04709 DiStella::disassemble is now called from RomWidget! Of course, the output
isn't actually sent to the UI yet (it's still printed to the console), but
at least the two parts of the code are now talking to each other.  Note
that the disassembly window in the debugger will be empty until I get this
changeover complete.  And with that, I'm not feeling well, so I'm taking
the rest of the night off.

stephena 898d16b863 Further improvements to the DiStella class. The output is now properly

printed out again.  The next change will be to pass this to RomWidget
and have it displayed in the UI.

stephena 231958dbdf Checking in current progress of DiStella class. The code now directs all
output to a specified function instead of the console.  The formatting is
also in a very fixed format.  That makes the next part easier; parsing
the output into a DisassemblyList structure that Stella can deal with
and show in the RomWidget.

stephena 28114a8c51 OK, this is the first pass at a huge reorganization of the debugger
classes.  First off, the distella code has been integrated into a
DiStella class.  This code isn't yet tied to the debugger, but it does
at least compile and generate valid output.

The RamDebug class has been replaced by a CartDebug class, which
takes responsibility for the previous RamDebug stuff as well as 
things related to Cart address space (read from write ports,
disassembly, etc).

Fixed E7 bankswitching when reading from the write port in the upper
256byte area.

Fixed 'read from write port functionality' in general for all carts
that supported it previously.  Basically, if _rwport is enabled, the
address is checked to be an actual read (vs. one that's part of a
normal write cycle), *and* it's actually an illegal access (each
cart/bankswitch type now provides a hint to indicate this condition).

Still TODO is clean up the rework, properly integrate DiStella, and
fix labels and defines (which seem to be completely broken).
