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

set on active transition of PA7 pin, cleared upon reading from TIMINT (but
only *after* its result is included in the TIMINT read).

display modes wrt both palette and display properties (# of scanlines,
size of window, etc). This means you can now dynamically switch
between these modes at runtime.
Also added 'Shift-Control-f', which cycles through the modes in
reverse order.

that picky (OCD would probably be a better description).
Bumped version #.

decision is final. It's time to move on, folks.

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.

RAM to do so, which I agonized over for about a week, but I feel it's
a fairly good tradeoff for the features we get. Eventually, I may come
up with a more accurate phosphor mode which eliminates this approach
entirely.
Reverted OpenGL framebuffer to 32-bit colour mode. We're using Blargg
effects, so we may as well get the full fidelity out of it. Besides,
testing has shown that there's not much speed difference between 16
and 32 bit modes, making me think that 16-bit is probably be swizzled
to 32-bit anyway.
Bumped release date to June 1, version to rc1.

for phosphor effects. It's just not ready to go yet, more research is
needed, and I just don't have the time to fix it. Besides, it's been
two months since the last release, and I need a vacation.
Because of this, the release date is changed to May 25.

instead of the entire area. This fixes the speed regression from 3.6,
since the main TIA texture is now larger than before. Previously it
was 160 pixels wide out of 256 total (rounded to power of two), now
it's 560 wide out of 1024 total. In 3.6 it was updating a buffer 256
pixels wide, in the latest beta releases it was sending 4 times as
much data (256 -> 1024). Now it sends only 160/560. Similar
improvements happened with the height as well (210 lines vs 256).
On my test systems at least, this is an extremely large win,
resulting in similar speeds as 3.6 even though we've moved to a 32-bit
framebuffer.
Bumped version # for next beta release.
Pushed release date to June 1, to make absolutely sure I have
everything fixed and ready to go.

now load and play test ROMs, complete with emulation of timing delays
due to slow accesses on real Harmony hardware. Still TODO is the tunes,
DPC+ stuff, which is stubbed out at this point.
Fixed bug in EFSC bankswitching; state files didn't contain extended RAM
information.
Cleaned up the Serializer API, resulting in slightly faster operation
and smaller state files. Because of this, the state file format
has changed for this release (old state files will no longer work).

instead of having different keys to turn them on and off separately.
This brings the functionality in line with the rest of the objects/
collision key-combos, which were also toggle-only.

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.

normal control functions (ie, pressing Ctrl-q will not quit, but send
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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2418 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.

shifted keys from the keyboard. Most control-keys are
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).

Renamed various 'Fire' button events to prevent the above problem
from happening again.
In BoosterGrip games, the right mouse button now sends the 'booster'
event, allowing one to play Omega Race fully with the mouse.

at which drawing first occurs.

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.

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.

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.

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.

contents. The file was being accessed and read, but the commands it contained
weren't being executed! This bug appeared in April 2010, so it looks like
not many people are using this feature (or at least they're not reporting it).
Cleaned up a few compiler warnings in DebuggerParser class.
Bumped version # for beta release.

digital, hat and keyboard input.

The debugger 'saverom' command now uses absolute filenames, and by default
will save data in the users home directory if a proper path isn't included
in the filename. This fixes a major bug where ROMs were being saved to
the current or application directory, which in some cases were invalid
locations.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2250 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba

when changing between video modes). Added extra signature to the
bankswitch autodetection for the 4A50 scheme.

- it doesn't have a hotkey any more
- it is changed in the "Input Settings' UI, not in 'Video Settings'
- it only has meaning while in emulation mode
- it is enabled by default

Updated documentation with info about 2600-daptor, including
usage and its creator. Also included more in-depth explanation
for the various controller types.
Errors from the Thumb ARM emulation code are now caught as exceptions,
and thrown to the parent class instead of calling exit() and simply
crashing Stella. For now, the messages are simply printed and
emulation continues. This will be expanded to show a detailed crash
log in the debugger, and offer the option to exit the ROM.
Removed most of the menus from the OSX port. They weren't being
maintained anyway, and most of them didn't work. I've modelled this
on the way other cross-platform OSX programs work (notably, ScummVM).
Basically, there are menus for exit and help, but otherwise you
should use the menuing system in the application itself.

which are specialized paddles classes that invert the axis, direction,
and axis+direction, respectively. Updated all applicable ROMs in the
properties database.
Cleaned up the menus in the OSX port; some of them weren't even tied
to anything. I'm seriously considering removing them all, except for
the Help and Quit items.

- mouse can now emulate joystick, booster-grip and driving controllers
- digital and mouse sensitivity for paddles can now be tweaked
separately, and have a greater range
- the mouse now correctly honours its controller setting, and only
controls a device on one one port (not both at the same time)
Added support for 2600-daptor device. Credit for creator of device
is forthcoming. This device is basically an updated Stelladaptor,
with improved handling for paddle data.
Grabmouse functionality is no longer user-definable; the mouse is
always grabbed while playing a game, and released otherwise.

access, because generally you'll want to audit the directory you're
actually looking at.

much free time over the past month or so.

Removed reference to disassembly 'SKIP' command, since it isn't implemented
yet.
Decided on Nov. 15 for the 3.3 release date, and updated all relevant files.

emulation core, and distella). This allows to better see exactly how an
address is marked in the disassembly.
Updated Changelog with changes I forgot that I made (you know it's time
for a new release when you forget what's been added since the last one).

screen size (vertically), the window will open in partially truncated mode,
where the top of the PAL image is cut off. This normally won't be a problem,
as it's mostly blank space anyway.
App window centering is now honoured when changing video zoom levels, not
just when changing eventhandler states.
Bumped version # for another test release.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2135 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
'Virtual Devs' tab to 'Devices & Ports'. Updated documentation and
snapshots for this change.
Added Halo 2600 ROM info to internal properties database.
Increased default setting for 'joydeadzone' from 0 to 13. This means
the default deadzone is somewhere around half the axis range (~16500).
Fixed behaviour of hat events; events weren't actually being turned off
until the stick was centered.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2108 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
Added 'ramrandom' commmandline argument, used to toggle randomizing or
zeroing or all RAM in the system (both zero-page and SARA).
Disassembler now properly supports all test cases, including rewinding
within the debugger.
Added preliminary support for disassembling from zero-page RAM.
Bumped version # for final release.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2100 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
The disassembler now accepts a range of start addresses and remembers
old entry points, so the disassembly becomes more complete each time
the debugger is used.
Changes to address offsets within the same bank are now supported
(ie, changing from $fxxx to $dxxx within the same bank properly
updates the display).
Re-added ability to manually change banks from the debugger prompt
and the disassembly UI. This now works correctly with the Distella
code.
Cleanup of the Cartridge::bank(...) API: if a bank cannot be changed,
the calling code will now know about it. This fixes confusion with
some ROMs, whereby changing a bank in the debugger prompt would print
a success message even if the operation failed.
Note that these changes have broken rewind in the debugger. Actually,
it only exposes problems that the rewind functionality already had :)

matched anything most of the time. Also, as this operation can take
a somewhat long time on slower systems, a progress bar is now shown.
Fixed handling of bit 6 in VBLANK TIA register, which is related to
how INPT4 and INPT5 are handled. This fixes at least one ROM that
should have failed in Stella, but didn't.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2096 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
is update the documentation for this.
Fixed bug reported by Buzbard from AtariAge concerning very large images
in the RomInfoWidget being clipped too small.
Reworked 'center window' functionality. Using the SDL_VIDEO_CENTERED
environment variable was always a hack, and a bug was introduced in X11
OpenGL mode in version 1.2.14. However, since SDL is now in maintenance
mode and won't be receiving any further updates, we have to bypass it
entirely. Added infrastructure for OSystem to center the application
window. For now, only Linux X11 mode is supported. Still TODO is add
support for Windows. OSX was never supported anyway. This also means
that the center window variable no longer requires the application to
be restarted.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2091 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
(ie, disabling from the UI kills the UI on future runs, so you can't
enable it again). This should fix problems where users go
'click-happy' in the UI, turning options on and off just to see what
happens.
Added 'showinfo' to the UI, so you don't have to drop to the
commandline to use it.
Updated all release files and bumped version number for 3.1.2
release.
