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 2cc0d60940 First pass at adding 'hints' to each Cart class that its bank has changed.
This is very useful for conditional re-disassembly, since many bankswitch
schemes consist of ROM only, and once disassembled, cannot possibly have
a different disassembly at some later point.  This is mostly done for such
static schemes (2K, 4K, etc), but more work is required for carts with
extended RAM.  Basically, the cart knows best how its been accessed, so
it makes sense to have the hints there.

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 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).

stephena e234139a3c Updated Stella headers in all files:
The license file is actually named 'License.txt', not 'license'
  The 'Stella Team' has a capital T, not lowercase.

stephena 6144e4fd57 Improved ROM launcher so that going to a parent folder automatically
selects the item that was previously selected.

Fixed bug in Cheat dialog where editing a cheat didn't remove the old one.

Updated TODO, rearranging improved disassembly as the #1 priority for the
next release; I don't have time to finish it now.

stephena 33130a78f0 Updated 'Fixed Debug Colors' for PAL mode to more closely match the ones
in NTSC.

First pass at disassembly of ZP RAM in the debugger UI.  For now, the
entire range is disassembled, with no regard for alignment (so the PC
won't necessarily always line up with the disassembly).  Also, changes
to RAM don't yet trigger a re-disassembly.

stephena 82325b731c Reworked the extended RAM editing in the debugger, allowing for those
schemes that have multiples areas of RAM.  Converted F4SC, F6SC, F8SC,
FASC to this new functionality.

Added ability to modify extended RAM in 3E, CV, E7 and EFSC ROMs.
Note that these ROMs can swap RAM in and out dynamically, so what
you see in the RAM area won't always be RAM.

Updated debugger CpuWidget; decimal and binary values for SP/A/X/Y
are now all shown at the same time (previously the registers had to
share a decimal/binary view).

Updated debugger documentation for recent additions.
