options have changed names. In particular, all tia-related options
now start with 'tia.'. This includes most of the old options that
started with 'gl_'.
Changed the names of all tv-effects options from starting with 'tv_'
to 'tv.', to match the name changes elsewhere.
Some work on the documentation to reflect the latest changes.

SDL-specific code into its own EventHandlerSDL2 class. This is part
of a larger reorganization of the codebase, to completely remove
SDL-specific code from src/emucore, and make it easier to port to SDL2.

reading these commit logs.

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.

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.

of bold and normal fonts within the debugger UI. Because of the # of changes
this requires, this is as far as I'll willing to go with UI configurability.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2820 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
extended abilities (see changelog and docs for more info).

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
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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2768 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.

that currently accept StringMap to use Variant instead.

'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.

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.

Distella '-r' option (Relocate calls out of address range) to
the disassembler core. Also added UI item to dynamically
change the setting.
Renamed 'resolvedata', 'showaddr' and 'gfxformat' commandline
arguments to start with 'dis', indicating that they're part
of the disassembler.

Settings::loadConfig() and Settings::saveConfig() when required.
This fixes an issue with OSX in particular, or any port where
those methods are overrided.

the Video Settings UI. Still TODO is add key shortcuts for the various
adjustable TV effects (contrast, brightness, etc).

'tv_scaninter' option. Added Alt-8 keypress to toggle this; still
TODO is add a UI item for it.

left to do, but the basic functionality is now there. Alt 1 - Alt 6
selects among TV modes as follows: off, composite, svideo, rgb, bad and
custom. The latter is just composite at this point; there's no code to
actually change specific adjustables yet. Alt 7/Shift-Alt 7 increases/
decreases scanline blend intensity (20% - 100%).

fixing bugs too numerous to mention. The end result is that using
Control-0 to switch between mouse modes is much more understandable.
Updated properties database for Telepathy ROM, which now uses the
MindLink controller. Also updated Astroblast ROMs to use paddles
by default.

Alt-f will toggle the filtering, but there's no output yet.

'saport'. This takes the values 'lr' or 'rl', corresponding to left/right
and right/left.
Added ability to dynamically swap the Stelladaptor/2600-daptor ports
with the 'Control-1' key.

Checking in first pass at revamping the 'mcontrol' functionality. The idea is
that the mouse will be able to emulate different controllers on each of its
axes. For now, the left mouse button is tied to the X-axis, and the right to
the Y-axis. These modes will be saved per-ROM, meaning that the mapping can
be different for each ROM (it is saved as part of the ROM properties). Only
the paddles and driving controllers will allow this, since they're the only
controllers where a single axis makes sense.
Switching between mouse modes will be done with Control-0 (the Control-1..3
keys have been removed). This will allow switching all possible combinations
(left controller, right controller, per-ROM setting, etc).

these logs!
Moved TODO and Credits info directly to the webpage, where it will hopefully
be easier to maintain.
Fixed 'crackling' sound when loading a new ROM, introduced with the 3.5
sound restructuring. It looks like stale data was being loaded by the
sound processing callback. As well, moved the computation of certain
division variables from the sound callback to the framerate re-calculator
(where it's recomputed 1/5 of the time or less).
Updated AboutDialog with info about Stella DonationWare status, and active
members of Stella development.
Updated OSX in-app HTML documentation about Stella DonationWare status.
Bumped version # to 3.5.1_svn, and the process starts again.

Eventually I'll find a more elegant way to represent this.

Updated documentation for impending 3.5 release.

when it isn't needed. According to SDL this shouldn't be necessary, but
some combinations of video modes and audio hardware cause sound to stop
working if it's repeatedly opened and closed. So we have to keep it open.
Always attempt to use 2 channels (aka stereo) when opening the SDL audio
device. This is now required, since ROMs can request mono or stereo mode,
and the sound system can no longer be closed and re-opened with the
desired settings. So we need to always use 2 channels to accommodate
when it might be needed. This actually more closely emulates the 2600,
which does have two audio channels. The 'mono' vs 'stereo' ROM property
basically controls whether these channels are exposed (ie, does the
virtual console have two-channel audio hardware installed). In that sense,
these settings control how the channels are mixed.
Updated some settings to have more reasonable defaults.
Added acknowledgement for people that have donated hardware to help with
development.

They were being saved correctly for all sticks, but only loaded for
the first one.
Removed some redundant settings related to TV effects stuff.

ROMs with an odd # of scanlines will display the image in
black & white, just as on a real system.

saved per device, so that unplugging and replugging a joystick won't cause
the previous mappings to be lost.
All attributes of a joystick (ie, number of sticks, number of axes, buttons,
hats on each stick) are dynamic, meaning that hardcoded values are no
longer used, making the handling more robust.

desktop on OSX and Windows, and the home directory in Linux.
The associated commandline has been changed to 'snapdir'.
Added 'GL VBO' toggle button to the Video Settings UI, and in
general cleaned up its interface.

in this area.
Added commandline argument 'thumb.trapfatal', which causes fatal errors in
the Thumb ARM emulation to really be treated as fatal (ie, the emulation stops
and throws an exception). This is enabled by default (as it always should be).
When disabled, fatal errors simply log the error and continue with emulation.
This was added because the current HarmonyCart ARM code isn't always exactly
compatible with the emulation in Stella, and there is a lagtime from when
Harmony implements something to when the same functionality is added to Stella.

compliant. It actually went smoother than I thought it would.
This show allow Stella to run well on *any* hardware-accelerated
OpenGL machine, not just those with beefy video cards.
Cleaned up the code a little, removing more references to the old
OpenGL TV filtering (which will be replaced by Blargg NTSC
filtering soon enough). Also removed 'gl_texrect' option, which
specified to use the GL_TEXTURE_RECTANGLE_ARB extension (for
non power-of-two textures). It was never enabled by default,
didn't work with ATI cards, and wasn't accessible in the UI,
so I doubt anyone will miss it. Besides, it's not supported in
OpenGL ES 1.x.
Next is to look into VBO/PBO, to see if more optimizations can
be done.

don't normally use the commandline (mostly Windows, but in some cases OSX as
well). The 'showinfo' commandline argument has been renamed 'loglevel', but
it has the same purpose. A new option 'logtoconsole' has been added, which
determines whether log output should also be directed to the commandline/
console (previously, it was always printed to the console). All these items
are now accessible from Options -> System Logs.
For anyone reading this (and that cares), now I can finally move on to the
OpenGL rewrite. The plan is that the new code will use OpenGL ES, which
is a subset of OpenGL 1.5. The main advantages are that you won't need
an advanced OpenGL card, and OpenGL ES is supported on most new 'smaller'
systems (iPhone, Android, etc), making ports much easier.
