have been changed to 'SDL2'. From this point on, the OpenGL-specific
code will be removed, and replaced by SDL2-specific hardware-accelerated
code.
Cleaned up (mostly) the API of FrameBuffer vs FrameBufferSDL2. Since the
FrameBuffer class is an emucore object, it should have no knowledge of SDL,
or any particular rendering toolkit for that matter (just in case we want
to move to SDL3 eventually :) ).
At this point, all checks for OpenGL have been removed, so if you don't
have it on your system, Stella will fail to compile and/or run.

64-bit Windows, so the name was incorrect anyway.

software rendering support. I've been wanting to do this for years,
and finally the time has come. So for now, you need OpenGL for Stella
to build and run.
Expect major breakage over the next few months, as I port to SDL2.

ever want to see the TIA, not the entire debugger area too.
This will be fixed for Stella 4.0, once I remove the @#*%$-ing software
rendering support. That part of the code keeps coming back to haunt me
for years. It will be *SO MUCH EASIER* to deal with these things when
everything is a FBSurface that can be stretched/scaled as necessary.

this requires, this is as far as I'll willing to go with UI configurability.

I wasn't completely sure how the file was structured, but it's starting to
make a lot more sense now. I think in the end, it will be better to use this
file as much as possible.
Bumped version #, and starting all over again.

number.name convention (which seem to be pass #'s for DASM). Initially
having this info in Stella was simply visually inconsistent, but now
it also interferes with recompiling when saving the disassembly (IOW,
the data put into the symbol file by DASM can't be fed back into DASM
again in these cases).

case where there is only one possible object below the register, a
'blank' uses the underlying colour (ie, in normal priority, a blank
PF is 'coloured' using COLUBK).

COLUBK instead of always using colour 0 (black). This is more
informative, as it displays how the registers actually work when
being drawn to the screen. Thanks to Tjoppen of AtariAge for this.

symbol names in the DASM symbol file). This partly fixes a deficiency in
symbol files, whereby two names could have the same address (one has an
address, the other as a constant), and Stella would use whichever one
occurred in the file last.

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.

Once a frame has started, it means a new frame should be added. This
fixes a bug in the debugger UI whereby the frame count showed the previous
value, since sometimes you could enter the debugger (with a cond BP)
before the end of the frame was technically reached.

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'.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2770 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba

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.

will be used, but at least we can improve it a little).
Eliminated the 'alignment' dimension in the various TIATables masks,
reducing the size of the arrays by a factor of 4. I could never
figure out what alignment meant, until I looked at old TIA code in
the repo. It seems that originally, there was an optimization
in the code to fill the array on 32-bit boundaries, instead of the
current 8-bit boundary. As a result, the masks had to be defined
as 32-bits, or 4 groups of 8-bits. Ah, that's where the 'alignment'
comes from.
Related to this, the colors and pointers in the TIA class are now
8-bit as well. Essentially, the TIA class has been doing extra
work to align everything to 32-bit and never actually using the
results. And it's been this way for 4+ years.
Older state files will no longer work, so the version # has been
bumped.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2765 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.

find it 24 hours ago, as it could have been included in 3.9.
Bumped version #, and starting all over again ...
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2762 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.

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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2743 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
Fixed bug after pressing Enter/Return in EditTextWidgets; it was exiting
from edit mode, which locked out certain key handling (these widgets
are always editable, and should not be exited in such a way).
Also, I just noticed the changelog file is exactly 2600 lines long :)

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.

- 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.

stuff into a new FileListWidget class (which will eventually be extended
to LauncherDialog as well).
The BrowserDialog now accepts different modes (file load and save, and
directories), and will be used in all places in the code where the
user currently has to type in filenames, etc.

and causing some ZIP files to not open at all.

Some cleanup of the various enum's in the UI classes.
Fixed issues with ordering when adding dialog boxes; this fixes a
bug when adding a dialog from another dialogs ::loadConfig(), in
which case the first one is placed below the second and can't be
seen (mostly applies to MessageBoxes).
Fixed bug in handling OSystem::setBaseDir(); if the directory didn't
exist, then the newly created one wouldn't have a slash appended at the
end. This causes all further (sub)directories to be created/named
incorrectly.
Started work on extending BrowerDialog to load files as well as
directories, and to allow editing of the items from within the dialog
itself.

That's it for the bankswitch schemes. Now I can move on to the
remaining items for the 3.9 release.

the debugger with a context menu still onscreen locked that widget, and
it couldn't be selected again ...

virtual keyboard added to the UI at some point).
Cleaned up the CheckBoxWidget API, and introduced new checkbox
'contents' that will hopefully more clearly indicate what is going
on (fully drawn square means selected, square with empty circle means
selected by not editable, etc).
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2706 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
disables normal keyboard input when in the debugger. This fixes issues
where commands/shortcut keys typed in the debugger would be interpreted
as actual CompuMate input.
For now, in-debugger key processing is completely disabled in such a
case. Eventually, we should probably add a virtual keyboard to the
CM RIOT area, and have it send its data directly to the CM handler.
Bumped version # slightly. I hope to get the next release ready to
go in a few weeks.

show the display bank, frequency bank and DPC Harmony RAM. Or
maybe there isn't a need to see this extra stuff??

The remainder of this commit is basically some cleanup of the
Widget API, and infrastructure fixes to allow CartDebugWidgets to
have change tracking.

it only contains the same functionality as F8; it needs to be
expanded to show more DPC-specific stuff.
Updated all schemes that contain a fixed RAM address range
(mostly the Superchip ones) to exclude that range from the
accessible ROM area.

to erase/load/save the Flash memory in the FA2 scheme (it's stored
in the Harmony cart, but emulated with a file). This is a debugger,
so it might as well have access to all the lower-level stuff in
the cart.

unsupported).
Implemented changing banks for MC scheme (although no test ROMs
exist, so we don't even know if the scheme works).

never actually included info on how to enable/disable it.
StringParser is now width-sensitive, in that it can also split
on a maximum string length. This is useful for making the various
UI items font-size independent, and to flow the text accordingly.
Increased minimum size of debugger window to 1080x720, which allows
things to be laid out a little nicer, and gives some much needed
extra room. Sorry guys, the most common resolution now in use
is 1366x768, so it's time to move with the times.
Cleaned up some of the descriptions in the ROM debugger tab(s).

since the current bank is at address-level resolution, and
it would immediately change back upon the next address change.

ContextMenu dialogs.
Tweaked bankswitch autodetection for 29K ROMs; the only possibilities
are ARM (FA2) or DPC+.

new functionality works.

esoteric schemes (ie, the ones that no longer follow the '4K per bank'
design). Arguably, this is the entire point of adding the cart-specific
debugger ROM tab; to make it easier to work with such schemes.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2689 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
For now, only 4K is shown. Eventually this will be included for all
bankswitch types, whereby the UI will be tailored to the specifics
of each scheme, so that ROM/RAM banks will be able to viewed and
changed more easily.

(for now, only the debugger, but might as well deal with the problem
in a general way once and for all). The Shift-Left/Right keys now
work as they did before, and switch between tabs in a tabset.
For dialogs with multiple tabs, it now selects among those tabs
where the focused object is. Clicking on another tabset then changes
the focus, and allows the same keys to switch among *that* tabset.
Now I can finally start the cart-specific bankswitch UI items.

debugger. In the process, I had to spend several days extending
the UI/dialog class to actually contain multiple tabs. This was
harder than expected, and it still isn't quite finished. In many
ways, we're beginning to reach the limits of the current code; it
was never designed for a full-fledged, graphically rich UI.
For now the tab is empty, but eventually it will contain general
info about the ROM bankswitch type (size, virtual layout, etc),
but also cart-specific info, including the ability to change
banks, which can be vary greatly among the different schemes.
Eventually, it may even allow to see/modify very cart-specific
info (like display RAM in DPC, etc).

(mostly because many ROMs released in the past 10 years make
extensive use of illegal opcodes).

out-of-range labels for cases where a label is in the middle of a
multi-byte instruction (Kool Aid Man), and properly indicates
mirrors of TIA read/write addresses (Meltdown).

- Removed 'SKIP' directive, since it wasn't implemented anyway, and
I see no way to implement it
- Add 'aflag' setting to diassembly output, matching usage in Distella.
This is needed for diassembly output, otherwise DASM barfs on the code.
- Fixed several long-standing bugs in Distella disassembly wrt ROW
directives and labeling. Previously, the output you see in the debugger
wasn't completely correct, since it wasn't compiling properly in DASM.
- Illegal opcodes are now shown as .byte directives; this allows the code
to compile in DASM.
- Print 16 bytes per line in .byte directive in external disassembly,
same as Distella.

a ROM, not creating a new one completely.

DiStella works, so you don't have to include a vcs.h file.

working quite well for a single-bank ROM, but more work is required for
multi-bank. Output is currently sent to the console, as I'm still in
the formatting phase. Saving to a file will be easy once the format
is nailed down.

set defaults.

TODOs and pointed out areas where improvements are likely needed,
in preparation for asking for help in the implementation.
Turned off 'resolvedata' in the debugger when disassembly ZP RAM.
It seems to be buggy in certain cases, and it's easier to just
leave it off in that mode, since (a) not many games run from ZP,
and (b) it's only at most 128 instructions.

'BASEDIR'/nvram. Previously it defaulted to BASEDIR, which was getting
filled with many such files.
Unfortunely, all files will have to moved manually, but it's an easy
one-time operation.

That is, it has all the functionality of past versions, as well
as improvements to launching from the commandline (an archive
containing multiple ROMs will now open the virtual directory
in the ROM launcher.

(automatically loading the first ROM when only one exists, or when
the name of the ZIP file itself is used).

it's still partially broken).
Converted many methods to take FSNode objects instead of raw string
filenames. This is necessary since file reading will eventually
be abstracted into the FSNode class directly.

opening ROMs, but at least the ROM launcher now properly descends into
ZIP 'folders'.
Removed obsolete unzip.h|c code, which hasn't been updated since 1998
and fails to compile on some systems. Replaced it with ZipHandler class,
which is a much nicer interface (and about half the code too).

broken ATM.

'ZipFilesystemNode' class, whereby ZIP archives and their contents are supported
natively by Stella.

Removed various 'Image' and 'Greeting Card' ROM info from the database;
the info was incomplete, and there's no way that I'm going over 7000+
ROMS to add them all. Eventually, I'd like the database to be for valid
ROMs only.

the sound is now much more accurate in "Space Rocks", and there aren't
any regressions that I'm aware of.
Removed 'clipvol' setting, since the sound is now 16-bit and clipping
is no longer required.

less CPU usage, so it should be much better on slower systems.

inconsistent scanline counts on every single frame.

I hope to get back to Stella development soon, and do a new release
in perhaps the next month or so.
