this combo directly to CompuMate).
Mapped Func-Space to the Backspace key for CompuMate keyboard.
Func-space (which is actually Ctrl-space is still supported).
Updated documentation for CompuMate changes and system requirements.

z26 code never actually implemented this, so I'm not sure how people
actually entered Basic code. I guess not many people have played
with and tested this before.
Added more sensible keys for the CompuMate 'space' and 'enter' keys.
They're still mapped to '/' and ';' respectively (to keep locations
on the keyboard the same), but are also mapped to the actual 'Space'
and 'Enter' keys (to make usage much easier). I'll probably also
map 'Shift-;' to Backspace as well.
Updated documentation for CompuMate emulation.

supported too, but still TODO is allow the Control key to
pass to the CompuMate controller and not pre-process it
by the EventHandler (so pressing Ctrl-q) shouldn't quit
emulation in that case).

- 'rom_diff.pl' command inspects two directories and looks at differences
in filenames, and copies ROMs into 3 new directories (ADDED, REMOVED,
and CHANGED). This is most useful for when RomHunter releases new
romsets.
- 'merge_props.pl' command merges all properties from a source file that
also exist in a destination file. This is useful when I do a mass-edit
of many ROMs, with the info being saved into my personal stella.pro file.
Running this command afterwards will 'merge' them into the master
stella.pro file, and then Stella can be recompiled with the new properties.

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).

generic than SDL, but less generic than simply using int's for everything.
This will help once we start porting to SDL2, which has an updated keycode
handling system. The plan is that the internal core keyboard stuff is now
insulated from any further changes in SDL.
This also allows eventually adding support for CompuMate controller,
which needs access to keycode names in a generic way.

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.

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.

All attributes of a joystick (ie, number of sticks, number of axes, buttons,

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.

from this point on, since I don't have to worry about breaking one mode

In the process of converting the code to be OpenGL ES compliant, we shouldn't
hurt the performance on systems with more advanced versions.

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.

buffer overflows. Also moved from static arrays to stringstreams

of the C++ standard.
Fixed bug when using snprintf; we must use BSPF_snprintf, since the function
has different names in different OS's.
Optimized loading of PNG images in the RomInfoWidget so that memory allocations
aren't continuously being done. Basically, memory is allocated once and then
only re-allocated if a new image is larger than all previous ones. This can
increase memory use slightly, as the image data stays around between image loads,
and it remembers the largest image loaded. But if you images are all mostly the
same size, it should hurt memory usage too much. And it really helps on certain
systems where repeated (re)-allocations can cause problems.

Blargg NTSC filtering, but we need to revert to base functionality first.
Cleaned up the debugger API wrt converting values from integers to strings
(and vice-versa). There is now only one method for each of these functions,
rather than several ways to do so. In the process, convert from unsafe
sprintf functions into snprintf (eliminate potential buffer overflows).
The debugger 'print' command now indicates if any assigned label represents
a read-only location (R), a write-only location (W), or a read/write location
(R/W).
Fixed bug in DataGridWidgets (used in debugger ROM and CPU registers), where
scrolling the mouse-wheel would cause a segfault. Scrolling the mousewheel
now changes these items as expected.
