Clang 3.8, gcc 5, Visual Studio 2017 and Xcode 8 are now the minimum
supported compilers, and they all support C++14, so we may as well use it.
- Change all make_ptr to make_unique
- Change iterator begin(), end(), etc to const versions where appropriate
- Remove UniquePtr, since C++14 supports it natively
until after an instruction was executed. Also, toggle-able widgets
(pixel and bits) in the debugger can now be toggled with a single
mouse click, not a double-click. These fix issue #15.
This has been in patch form for about a year, and I'm finally
getting around to applying it. Basically, we separate the Cart
class into 3 classes:
- Cart: stuff specific to cartridge emulation
- BSTypes: various bankswitch types, both as enum and strings
- CartDetector: actual bankswitch auto-detection code
Also made more use of smart pointers, and added const in a few
more places.
I promise to get back to the phosphor stuff soon. This is just
to clear my head a little.
the fixed debug colors to user-defined preferences. Note that there
are 6 registers (P0,M0,P1,M1,PF,BL), and the option takes a string
of 6 characters, where each represents a colour for the respective
positional register (ROYGBP are the choices).
I may add a UI item for this, but this is as far as I will go with
allowing user editing.
The Harmony/Melody BUS driver is undergoing a major revision to add support for the new JMP FASTJUMP feature. This update implements the changes, as well as the fast jump feature which isn't yet in the HMdriver. It also implements the load/save state support as well as the BUS debugger widget.
A few minor updates to CDF were also done.
Note that this update breaks compatibility with the previous BUS demos.
* Implemented load/save state.
* Updated the debugger tab, which required the following:
- removal of : from RAM labels (part of the debugger overhaul)
- setCrossed() functionality in the DataGrid
to work like the old 'm' versions, so they work on all mirrors and
also allow one to enter a range of values to trap. Added more
stringent error checking for parameters.
- 'cls' now only clears the screen, and not the command history
- 'help' accepts another command as an argument, to give more info
about the command (ie, help breakif is now valid)
- command completion now works on built-in functions and pseudo-ops
* Add an iterator for interating over delay queue entries
* Dynamically build delay queue widget content from iterator
* Refactor shadow registers to reflect a possible delay
we need just a little more height. There's similar issues for the
smallest font, but I need to think about that one a little more,
since many people are affected if we change the window size at the
smallest setting.

Introduce namespace to class MD5, so the method call is now MD5::hash()
instead of simply MD5().
Added C++11 '= delete' constructors to most classes, to more clearly
indicate the intent of the class. Note that this isn't absolutely

DASH, but that one is still in development ...

the RAM is always mapped into the same place in ROM, the ram grid
now shows addresses with the correct read port address, and
ram labels are properly accessed. In cases where the RAM is hidden
from the 6507 or not mapped into the same place at the same time,
the addresses show actual real addresses of the RAM from the POV of
the cart itself (ie, RAM location zero is labeled 0, not as $1xxx).
This is necessary since quiescent RAM doesn't actually have a 6507
address. Also, labels are disabled in this case.
Fixed bug with incorrect offsets when reading cart RAM labels;
it seems to be a copy/paste issue, since all such methods were
written as if the cart was SaraChip-based.

This code was originally there for software mode, where it was very
expensive to update pixels, so it was done as little as possible.
However, it was also a bit of a hack, and sometimes interfered with
double-buffered hardware rendering. So now showing the various UI's

all conditions.

are also some fixes for minor warnings.
There are still some issues, though. First, SDL2.0.3 has to compiled

which I though a just a one or two-liner equivalent to glReadPixels.
Turns out that SDL2 doesn't return 24-bit RGB data (only 16 or 32-bit),
so the PNGLibrary had to massage the data. In the process, converted
the PNG saving functions to actually use PNG library functions, which
greatly simplified converting packing from 32 -> 24-bit. Historically,
the PNG save functions were written before libpng was a requirement,
so they were hand-rolled. Once libpng was integrated into the codebase,
it didn't make much sense to not use it anymore.
So an expected two-line code fix became this commit ...

Removed FBSurfaceTIA, since it was tied too closely to SDL itself. Added a
class called TIASurface that is functionally very similar, but is more generic

responsibility for all things related to rendering the TIA image (Blargg TV
effects, phosphor mode, etc).

on exit; it attempted to close the debugger dialog instead!

it was confusing which one was being called.
Fixed output in debugger bankstate info; in some cases, hex numbers were shown
when decimal was required.
Fixed regression wrt the last TIA change (incorrect framerate counter); the
PAL autodetection was failing in certain cases.

This is the beginning of a major cleanup of the bspf.hxx file, which
has gotten unwieldy over the years.

bases into a Common::Base class. Previously, this functionality was
spread across several classes, and used different approaches to formatting.
While the code still mixes C++ streams and C-style sprintf's, at least
it will now be easier to modify it all in one place.
Related to the above, added ability to use upper or lower case
characters for HEX output in the debugger. This is toggled by the
new debugger prompt command 'uhex', which is also tied to a new
commandline argument, 'dbg.uhex'.

the CPU registers (A/X/Y/PS) on ROM load.
Added 'INTIM Clks' to the debugger I/O tab, showing the number of clocks
before the current INTIM value decreases by 1.

in decimal, not hex.
All DataGridWidgets (ie, most of the inputs in the debugger) have more
strict input filtering, allowing to use $,#,\ specifiers for different
bases, as well as restricting input based on the specifier used (ie, if
you've entered a '\', only '0' and '1' are allowed, etc).
Updated libpng to latest version.

Cleaned up the class comments wrt ScummVM; the attributions only needed to
be in the base classes, since all the derived stuff was written later.

Added option to save snapshots using either internal database name
(the default) or actual ROM filename.
Extended FSNode API for parsing filenames and adding/removing extensions,
which was previously being done in different ways throughout the codebase.

This will eventually grow to include all relevant options in Distella.

selection widget to a display of current bank state, taking into
account the more esoteric bank schemes. Currently, some functionality
is disabled/removed for now; I'll work on this for the next commit.
The format for displaying disassembler GFX/PGFX (binary or hex) is now
obeyed in the disassembly file output as well.
Changed various comments/enums/etc referring to 'preliminary' code to
'tentative' code, matching the actual intended meaning and the current
documentation.
Small API change for EditTextWidget; changed method name to setText, since
that's what I keep typing for some reason.

initial pass of the disassembler. This was required in certain cases,
notably when issuing 'savedis' when the code was currently running from
zero-page.
Fixed missed labels for zero-page RAM when running ZP code.

to an external file.
- RIOT/TIA mirrors are now used whenever possible. This includes *all*
possible mirrors in the entire 64K address space. This was needed to
make the disassembly byte-exact when recompiling the ROM.
- Disassembly to a file now includes all required defined constants
(RIOT/TIA, non-locatable labels, user-defined, etc).

for single-bank ROMs, same as disassembly (since the underlying framework
has been modified). Second, it now actually works :) I can't see how it
worked before, and since I didn't get any complaints/reports, I really have
to question how much use this code actually gets.
Still TODO is fix errors in CODE vs. PCODE (preliminary code) (in
the Distella code, we should clearly mark the difference).

For now (and the next release), filenames are hardcoded to sane defaults.
Eventually, the code may be extended to use BrowserDialog to query the names,
but it's taking much too long to get working, and I want to get a new release
done before the end of May.

converting StringMap to VariantList. In the process, some of the
code is much cleaner, and the Variant infrastructure allows
work to continue on a more full-featured ContextMenu.
