cases, these archives contain directories named '__MACOSX' which
contain link files that were being erroneously detected as actual
ROMs.
Added FilesystemNode::isFile() method, and updated several places
in the code to use it. Previously, determining whether something
was a file was simply testing if it wasn't a directory, but this
logic isn't always valid (it's possible to be neither a regular
file *nor* a directory).
Bumped version # for RC release. It's getting very close ...

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%).

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.

to realize over the years (and in particular with reading the C++11

some of them at least.

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.

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.
Bumped version # to 3.5.1_svn, and the process starts again.

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'.

general cleaned up its interface.

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.

BSPF_snprintf instead, which should eliminate any potential
buffer overflows. Also moved from static arrays to stringstreams
where appropriate to make things safer and more C++ like.

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.

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.

This basically shows a messagebox as soon as the debugger starts,
describing the error and offering the choice to continue debugging
or exiting the ROM entirely.
The DPC+ code now catches fatal errors from the Thumb ARM
emulation code and shows it as a fatal error in the debugger.
This means you no longer need to look at the commandline for
this output, and you immediately know that something has
gone wrong.
Added 'exitrom' debugger parser command, which completely exits
from the debugger *and* the ROM, going back to the ROM launcher.
Cleaned up the API a little, rearranging some classes and
adding references instead of pointers. More work to be done
in this area.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2234 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.

- 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.

multiple concatentation of strings. This should be faster, or at least
lead to less string constructor calls.
Output of 'ROW' directives in the disassembly now shows only 8 items per
line, instead of 16. This allows to see all the bytes without having a
'...' in between. A future release may customize this to the size of the
output area.
Fixed output from debugger 'disasm' command to properly align different
directive types and show GFX and PGFX output.
Bumped state file version to 3.3 final, since there are no further
changes to the code that will break the file format.

detection and marking of those areas into the TIA class itself, specifically
at the location of the write. In other words, there's no longer an IF
statement executed for every STx opcode; the marking is done directly
within the write to GRPx or PFx, so extra code is only executed when
actually storing to those locations.
Fixed several cases of opcodes marking an area as CODE when it should have
been DATA.
Added output to the CPU area of the debugger for displaying the source
address for loading data into the A/X/Y registers. Note that these are
only modified when actual addresses are used, so immediate and zero-page
mode will show addresses as zero (meaning that no address was involved
in retrieving the data).
Tweaked console font to better diffentiate the disassembly output between
graphics for players and graphics for the playfield.
Bumped state file format because of changes to M6502. This means old
state files will be broken.
Bumped version # for next test release.

previously defined GFX directive is now used for player graphics
only). The 6502 core tracks each of these separately, which provides

allows gives much more informative disassembled outout.

Effective C++, and including only what's absolutely necessary. For
definitions that don't need to be included, the designation 'class xxx'

where the top of the PAL image is cut off. This normally won't be a problem,

Basically, directories are now guaranteed to always end in the path
separator. Ensuring this makes certain sections of code work faster,
and guaranteeing it allows higher layers of code to not worry about it.
Added 'cfgdir' commandline argument, to specify the default directory

'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.

zeroing or all RAM in the system (both zero-page and SARA).

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.

Still TODO is implement saveConfig(), to send the new events to EventHandler.

scrolling with the mouse wheel (previously, it always scrolled at 1 line
at a time).
Updated OSX project files for recent ComboDialog addition.

1) Added a 'Reset' button to the UI, which resets (to defaults)
the currently selected item. This is more fine-grained than the actual
'Defaults' button, which resets *all* events.
2) Rearranged some buttons and resized UI. There is now a main 'Defaults'
button on the bottom of the dialog, which applies to the currently selected
tab. This also allows to set defaults for Virtual Devs, which didn't have
such functionality previously.
3) Added a 'Combo' button to the Emulation events tab. It doesn't do
anything yet, but eventually will allow to assign events to the 'combo'
events.
ContextMenu/PopupWidget now supports the scroll button on a mouse when
in scroll mode.

PopupWidgets now have arrows that support scrolling, without having to

changes to disabled when they reach the upper or lower range.
Also, the maximum number of items shown in a ContextMenu is now 16,
which looks quite a bit nicer than showing 30 or so all at once.
ScrollBarWidget now looks a little nicer, as the scroll bar is a little
wider, and the arrows are larger (same ones from ContextMenu). As well,
click and hold works on the scroll buttons, even during mouse movement.
This means you no longer have to hold the mouse completely still to
get continuous mouse click events.
Dialogs can now register whether they want to receive continuous mouse
click events (aka, click and hold of a mouse button). Most dialogs
don't need it, and some even work incorrectly when it's activated.
This fixes a bug in ContextMenu, where click and hold on a PopupWidget
would continuously open and close the list of items.

Stella can use (320x240). The app should no longer crash in such
low-res situations.
Various improvements to the UI, adding many finishing touches. The
text is more descriptive, and the options are somewhat better labeled.
As well, the available options are better presented based on the
restrictions currently in use (ie, if the maximum resolution is very
small, then the high-res resolutions are not shown in selectors, etc).
Added MessageBox to ROM Audit functionality, to warn that it is a
dangerous operation and that a file backup is advised.
Updated OSX build script to not crash when an older image has already
been created.

all cases when using the 'maxres' commandline argument. Also, the
lower limit of 320x240 is now strictly enforced in all cases.

the UI.
Modified the ROM launcher to display a messagebox when running Stella for
the first time (which currently means when the 'romdir' hasn't been set).
This messagebox suggests setting the default ROM directory, and if the
user clicks on 'OK', only then is the ROM directory file browser
displayed.
Reworked some of the event handling methods in EventHandler to save
function calls on every event.

The event mapping for such events is now done on the release of the
axis/hat, and not on the first press. This should fix the remaining
problems with sensitivity, as the user must explicit press and then
release the axis/hat, with all other events occurring the meantime
being ignored.
Fixed bug in continuous events for axes/hats; event that represent
'off' should not be continuously sent.

axes. It shouldn't be nearly as sensitive now.
Cleaned up handling of joystick hats, and fixed continuous events
(so that holding down a hat now sends continuous events until the
hat is centered again).
Fixed bug in prune_snapshots script; it didn't work with a snapshot
directory name containing a space.

been chosen), a dialog box now appears, asking the user to enter the
default directory. This directory will appear each time the ROM launcher
is entered, until the user selects a directory. This will hopefully
eliminate bug reports from users that don't know what to do when first
starting Stella.
Big changes to the manual, separating the necessary, up-front information
from the advanced stuff that can be considered later (or not at all).
Also added more links to ease navigation. This should make the manual more
readable for those that have complained it's too long.
The setting for TV color type is now 'Color' and 'BW', instead of
'BlackAndWhite', as before. The old one will continue to work, though.

when sending axis events to the DialogContainer (ie, all UI-related stuff).
The UI code was originally written with this in mind, and wasn't designed for
analog input. For normal digital sticks, nothing changes. For analog sticks,
values are clamped to 3 points (max, min, off), and repeated consecutive
events are ignored. This (partially) fixes bugs in the UI, where pressing
an analog stick would cause the current selector to move very fast.
Added repeat mode for joystick hats, similar to joystick axes (so holding
down a hat will cause continuous events to occur. More testing is
required for this, as I don't actually have access to hats right now.

(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.

an outputstream. For now, the output simply goes to stdout or stderr,
just like before, but the possibility is now there to redirect to a
file if desired.
Changed 'showinfo' commandline option to accept 'levels' of output
instead of simply being a boolean. The new default is level 1,
in which normal messages are output during a run. Level 2 will
show more detailed info, and may be useful in debugging end-user
problems. There's still more work to do wrt level 2.

'File Settings' dialog
2) the commandline option is now named 'ssinterval' instead of 'ssdelay'
3) the action is tied to the 'Alt/Cmd-s' key instead of a function key
There's just one more small issue to take care of in the Windows port,
and the next release should be ready.

Also, it now accepts arguments as strings (never, always, auto)

Updated main documentation for changes in OSX port 'basedir'.
Updated debugger documentation for recent command additions, and
provided new snapshots where the UI has changed.
It seems to be getting close to a new release - perhaps this
coming Friday.

post-3.0), and reworked how state files are accessed. The cart type
now determines if a state file is valid, meaning developers can use
one state file across multiple builds of their program.
Added 'runtopc' debugger command, and associated UI item in the
RomWidget area. This steps the code until the PC matches the given
value.
Added '16in1' bankswitch scheme, which is useful for ROMs named
'128-in-1' in RomHunter database. Also, all multicart schemes now
show the current ROM onscreen while switching between them.
Fixed bug in Serializer class when accessing files in read-only mode.
Such files would be created and set to zero size, even if only
reading was requested.

release. This won't have everything I'd have liked to include,
but the release time has dragged on enough (the last release
was in Sept 2009!).
Some general code cleanups for the OSX port, as well as fixes
to the menus. The menus contained items that in some cases
weren't actually tied to any event, or showed the wrong
shortcut key. Also removed some of the more esoteric menu
items, sticking with only the most basic ones (fullscreen vs.
window mode, volume control, etc).

up a little nicer. More work is required in this area.

be started (if it's been enabled).

disassembler. Hopefully this will lead to a new release very soon.
Added 'autocode' commandline argument and associated UI item (in the
RomWidget debugger area), which controls how Distella will use the
'automatic code determination' option. If set to 0/never, this is
completely disabled. If set to 1/always, it is always enabled.
The default is 2/automatic, whereby it is first turned on, and then
turned off if the disassembly doesn't contain the current PC address.
RomListWidget has now been completely reworked, so that it informs
RomWidget of its intent to change breakpoints and patch ROM. If
either of these fail, the action won't be performed, and more
importantly, it won't appear onscreen as if the action has succeeded.
This fixes an old bug whereby patching could fail, yet the onscreen
ROM data was actually changed. Related to this, the list has been
made as efficient as possible, and its contents are never un-necessarily
copied. Also, lines in the disassembly that cannot be modified no
longer show an edit area.
Due to the way the new disassembly works, you can no longer switch between
banks in the RomWidget (Distella would probably fail to disassemble in
such as case).
EditTextWidget can now indicate its contents have changed when adding
text to it.

is now enforced in more areas of the code, specifically, in BrowserDialog,
VideoDialog and InputDialog.
Rearranged some options in InputDialog (for spacing), and removed the
'mouse is paddle ...' option. It was never being saved to the config
file anyway, and is still selectable with Ctrl-0,1,2,3 keys.
Added 'maxres' commandline argument, which overrides the built-in
determination of desktop size normally done by SDL. This is not
documented, and is not meant to be used by anyone other than those
testing Stella on 'small' systems. It's basically a way to set the
desktop size without recompiling Stella each time.
Still TODO is look at all other dialogs, making sure they fit in the
minimum size. PopupDialog in particular needs to be fixed.

that Stella supports).

properly distinguishes between intermediate reads which are part of writes,
and ordinary reads. In the former case, only a read which has a different
address than a write is flagged as an error; intermediate reads acting on
the same address as the corresponding write are considered normal, and won't
trigger a break.

undriven pins take on the last value on the databus. This fixes a bug
in those reads where bit 6 or bits 6 & 7 are also undriven (previously,
these bits would always be zero, and only bits 0-5 were from lastdatabus.
Added new commandline argument 'tiadriven', which defaults to false.
In this default case, relevant bits take on values from the databus.
If true, relevant bits still take on databus values, but some are
randomly driven high as well. This helps to expose bugs when
developers assume the values for undriven/floating bits.
Added 'uimessages' commandline argument and associated UI item. When
disabled, messages which are normally shown in-game are disabled.
Certain messages which indicate a serious error are still shown, however.

fullscreen mode switching'. This was added because some systems with
buggy video drivers can't handle fullscreen mode, and accidentally
trying to do so can lock up such a system.

switching from fullscreen to windowed mode had the cursor trapped in
the window, even if grabmouse was disabled.

simultaneously on a virtual joystick. This support was always present
for 'Bumper Bash', but it can now be enabled/disabled for any ROM.

class reworking. Serializer class now handles read/write of state from
files as well as in-memory streams. As a result, Deserializer class has
been removed.
Added state rewinding to the debugger. For now, this is limited to 100
levels of undo, with a new state generated each time a step/trace/frame/
scanline advance is performed. The undo level is 'rolling', in that it
remembers the last 100 levels (so you lose the oldest states when you
start adding more than 100). For now, this is tied to the 'Alt-r' key
in the debugger. Still TODO is add a button for it, and clean up some
TIA output issues when rewinding.
Added support for 6K version of Supercharger ROMs (this fixes issues
with the 6K version of Cubis).
Cleaned up the Serializable infrastructure, making sure that all
classes that need to implement it actually do so now.
Fixed issue with editable widgets in the UI, where pressing Enter
on the keypad wasn't actually being registered.

problems with integer overflow, which could sometimes cause Stella to
sleep for long periods of time. For those who are interested, the
problem was that SDL_GetTicks() wraps every 49 days (32-bit int
overflow), but since OSystem::getTicks() provides info in microseconds,
it multiplied the value by 1000. This caused wraparound in 49/1000
days, or 70.56 minutes. This almost exactly matches the reports on
AtariAge of 'lockups' occuring every 71 minutes or so. It also
explains why attaching to Stella with GDB and bypassing the delay
allows the program to continue (as reported by another bugtester).
Added signature to detect UA bankswitching for Gingerbread Man ROM.
Bumped version number.

it wasn't found.
The file being used by Stella in multi-file ZIP archive is now shown in
the window title, vs. showing the name of the ZIP file itself. Related
to this, a file with an extension of 'rom' is now valid inside ZIP
archives.

Randomized value placed in accumulator after exiting the SC BIOS for
SuperCharger ROMs. This should fix issues in Dragonstomper, where it
seems the randomization of its items depending on a random accumulator

Re-added '-fastscbios', and when enabled, it completely skips
the emulation of SC BIOS progress bars (previously, the bars were
simply sped up). This defaults to off, for more authentic emulation.
Related to this, added a UI item in VideoDialog to enable/disable it.

Added 'exitlauncher' commandline argument, which specifies the functionality
of the 'Exit to launcher' action; should exiting a game actually go back to
the launcher, or exit the program entirely. Also added a UI item in UIDialog
for this.
Reworked the fullscreen/windowed handling in FrameBuffer, simplifying the

previous releases. Also added websites where applicable.
Update AboutDialog to be more current, showing only those members
currently active in the Stella project and the other teams that have
contributed code. For more specifics, you should now see the manual.
Basically consolidated all contribution info into one document, so it
has to be kept up-to-date in only one place.

the debugger RAM UI. A scrollbar is now present, which can scroll
through each 128 byte 'bank'. Labels indicate the current readport,
so you can distinguish between different areas of RAM. For now,
F4SC, F6SC, F8SC, and FASC have been converted, but I'm looking into the
other schemes now.
The RAM UI takes care of all read/write port issues. From the POV of
the UI, the RAM can be treated as zero-page; translation is done
behind the scene. Searching/comparing and change-tracking are also
supported.
The 'ram' command in the debugger prompt now reflects all RAM, and
readport/writeport addresses are shown, making it easier to use the
command withot having to look up the offsets.
Debugger width has been bumped to 1050 pixels wide to accomodate the
new functionality. We'll see how much trouble this causes ...

'gl_texrect' is enabled. The VideoDialog now reflects this, by stating
a message, and disabling the UI items when not satisfied.

requirements for new TV effects (OpenGL 2.0+ and GLSL).

Added CRT simulation as described by Ian Bogost in the AtariAge thread
'CRT simulation for Stella. This is just the first pass, but things
are working nicely so far (for those systems that can support it). It
requires at least OpenGL 2.0 with GLSL (GL Shading language). Added
the commandline arugments 'tv_tex', 'tv_bleed', 'tv_noise' and 'tv_phos'
used to set these various effects, as well as the ability to set them
within the Video Settings dialog. More documentation is forthcoming
on this.
All bankswitch modes that use SC RAM now act correctly when reading
from the write port (the RAM is erased).
Patching ROMs with bankswitch type 0840, SB, UA and X07 is now working.
Went through all the bankswitch classes and converted multiplication/
division to shift operations whenever possible. It's a
micro-optimization, but what the heck; every little bit of speed counts.
