used as a peek operand). Still TODO is deal with poke areas, which would
be relevant in carts with extended RAM.
The interaction between the internal tracking and Distella is now much
tighter, in that knowledge gained by Distella is used in the core code,
and vice versa. This allows the best of both worlds, where the internal
tracking finds stuff at runtime (that couldn't be found in a static
analysis), and Distella tracks potential paths (that haven't occurred at
runtime yet).
Added 'type' debugger prompt command, which basically queries an address
for its disassembly type (CODE/GFX/DATA, etc).
Added debugger commands to query the last address used in an operation
for various registers, but they're only stubs at the moment.
Updated the bankswitch schemes to deal with accesses in and around the
hotspot areas. Previously, peek accesses in these areas weren't being
recorded as DATA areas.

realized that not all things that are referenced are actually data; code can be
referenced too.
Implemented handling of 'DATA' directive. This is very similar to 'GFX',
except X's are not shown for the bits, and the disassembled bytes are always
in hex. For now, it can only be activated manually with a cfg command.
Its real value will become apparent once the emulation tracks when
addresses are actually accessed, differentiating from addresses that are
never referenced (ie, 'ROW'). This will fix the current deficiency in
modifying DATA values (it can't be done, since they're packed into 16 bytes per
line and not changable).

in general) into the emulation core. For now, this means integrating the
directive names into CartDebug, and having Distella using those same names.
The new directive names were determined by discussion with Omegamatrix on
AtariAge, and are listed in order of decreasing hierarchy:
SKIP (the 'bit' trick to skip over sections of code)
CODE (addresses accessible to the program counter)
GFX (addresses where data is loaded into TIA GRPx registers)
DATA (addresses referenced somewhere in the ROM)
ROW (addresses never referenced at all)
The next TODO item is to have the 6502 core set these values during emulation.
This is currently (crudely) done with a true/false setting in System::peek,
where true corresponds to CODE. This will be extended, so that false
corresponds to DATA. Eventually GFX will also be detected, by watching writes
to the TIA GRPx registers. Still to work out is how to detect SKIP sections.
Anything not marked with one of the above directives will be marked as ROW,
which essentially means ROM space that is never used. This will have the
nice side effect of detecting dead ROM space, potentially leading to space
optimizations.

disassembly listing) to show/hide opcode/instruction addresses.
The disassembler now includes hints from current PC location *and* 'code
access points' from the emulation core. Testing has shown that some ROMs
don't show completely accurate disassembled output unless both options are
used.
Updated most of the remaining bankswitch schemes to use the new 'code access
points' functionality during disassembly, allowing for very accurate
disassembled output. Note that the more esoteric schemes (AR, 4A50, FE, MC)
are supported for now.

addresses used as part of code execution (ie, from the PC) during emulation.
This gives Distella much more information than can be determined from a
static analysis alone, resulting in an extremely accurate disassembly.
This also allows to generate very accurate debugger .cfg files.
Not all carts have been ported to this new scheme yet, particularly ones
having extended RAM that can be mapped out dynamically.
Note that this new scheme doubles the amount of RAM used for storing ROM
images, so up to 128KB extra will be used. There's also a small runtime
check for each instruction executed. Preliminary testing doesn't show
any slowdowns, but we'll see how it goes.

Symbol and config files are now loaded when the debugger is first entered,
not when the ROM is actually loaded. This speeds up ROM loading, since
the user may never need to access these file (ie, they may never enter the
debugger).
The debugger 'loadconfig' and 'saveconfig' commands are now implemented.

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
for Distella-like Stella-compatible config files.
Implemented 'loadconfig' debugger prompt command. It's currently
working great with several test config files provided by Omega of
AtariAge.

set the default display format for GFX data sections (currently, binary
and hex are supported).
Fixed bug in several debugger input areas to accept the '\' symbol.
This symbol is needed when entering data in binary format (it must
prefix the data if the default base for that field isn't binary).
Added 'jump' debugger prompt command, used to scroll the disassembly
to the given address (or there-abouts, if the address isn't valid).
Editing data in the disassembly now won't cause the display to jump to
the current PC. The display will only move to the PC when it actually
changes.

There was a bug in the linked list code causing directives to be added
incorrectly. Also, merging is now done when possible instead of
creating new nodes. This keeps the directive count as small as possible,
and also helps with memory (less allocations happening).
Fixed bug in printing the 'ORG' directive; it was being printed
before the bank was disassembled, so on the first run it was always 0.

longer simply added to a list, but intelligently 'merged' (so that
the entire range represented by all directives contains no overlap).
This makes the disassembly a little faster, since it doesn't have to
iterate redundantly. Still TODO in this area is intelligent insertion
for the same type (ie, if inserting in between like blocks, the
blocks should coalesce, instead of being clipped and then a new range
inserted in between).
Added 'loadconfig' and 'saveconfig' debugger prompt commands, which
will eventually access Distella-like config files. No implementation
is present yet.
Added 'listconfig' debugger command, which lists all directives
currently defined by the user, as well as the directives resulting
from a disassembly of a bank (taking into account extra knowledge
that Stella has WRT cached entry points). This command can show
information for a specified bank, or all banks in the cart.
User-defined directives can now be removed; simply issue the same
command that caused an insertion (ie, attempting to insert the same
type and range will remove it instead).
Fixed bug in Distella processing of directives; similar to the
standalone Distella, directives should be processed *before* any
automatic code determination is done.

pseudo-registers. Equates/labels and user-defined functions are
still a WIP, since they're stored in various hashtables accessible

Added Halo 2600 ROM info to internal properties database.
Increased default setting for 'joydeadzone' from 0 to 13. This means

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

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 :)

a somewhat long time on slower systems, a progress bar is now shown.

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.

these bits were ignored, and treated as high all the time. A recently

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.

Context menus, both as right-mouse button popups and those part of
PopupWidgets now have arrows that support scrolling, without having to
continuously click the mouse button. The scroll arrow color also
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.

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.

Also, fixed a potential future bug where Stella can't handle paletted
images. Basically, the error handling is now more robust.
Minor rework of the CartF8 class; it now looks the ROM MD5 directly and
decides if it's a 'special' ROM.
Several updates to the built-in properties database, including better
support for each game in the 8-in-1 ROM image.
Fixed crash in TIA handling of the playfield mask; it could cause a
segfault under certain circumstances.

well, but this hasn't been tested).

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.

Cleaned up handling of joystick hats, and fixed continuous events

hat is centered again).
Fixed bug in prune_snapshots script; it didn't work with a snapshot
directory name containing a space.

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.

for OSystem::getTicks() has changed to always output an increasing
value each time it's called, even between program runs (needed for
timestamps for continuous snapshots, but also for similar things in
the future). It does this by refering to some set time in the past,
which is currently the UNIX epoch.

so they don't overwrite previously created files. This timestamp is
related to the millisecond that the snapshot was taken, so there's no
chance of overlap (snapshots can only be taken every 1 second / 1000

representation of this 32-bit value.

The UNIX builds for Debian and Redhat/RPM now default to using the
builtin PNG and zlib libraries. This will ease issues at release
time, since we don't need to worry about those libraries being
present on the destination systems.

systems that use the configure script).
The debugger can now be resized in between ROM launches (ie, before
a ROM is actually started). Previously, the entire program had to
be restarted for resizing to take effect.

RomListWidget, which currently doesn't parse valid PNG files
that are generated outside Stella (in particular, those that
have been optimized and use row filtering).

For now, only the infrastructure is being modified.
Make disassembly output a little nicer by drawing a vertical line
separating disassembly text from the actual raw bytes.
Some changes to the SDL sound code initialization, which will (hopefully)
eventually lead to a fix for those users with ATI video drivers, and
not having sound after the first game has been played.

or from the user. Before this is done, the parser needs to recognize
variable-length labels (right now, it used fixed spacing and assumes
the largest label is 8 characters).
Fixed bug in Distella; a label was being printed with an incorrect
quote symbol, which would break parsing of that line.

Some minor cleanups to the Cart classes.

release.

(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.

These have ARM code appended to the beginning of the ROM, which is
(for now) ignored by Stella.
Improved memory usage for DPC and DPC+ schemes, so that an extra
copy of the ROM image is no longer required. This also fixes a bug
in the getImage methods, which wouldn't have actually returned any
changes made by patching the ROM (it always returned the original,
non-modified copy).

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.

of OSX. It was partially caused by 'negative time', or successive
calls to SDL_GetTicks() returning smaller values than previous calls.
This obviously totally confused the timing logic, which was never
designed for time to go backwards. Related to this, setting the
framerate to 0 from the VideoDialog UI (indicating that auto-frame
should be used) ended up setting the time-per-frame to approx. 71
minutes, resulting in a delay of 71 minutes to the next frame
(which is what caused the 'lockup').
Changed all references to the Intel OSX build to also mention OSX
Snow Leopard (10.6), since the build won't run on 10.4 or 10.5.
Bumped version number to 3.1 (again). Hopefully this is good to go.

to bump it again.
Rant mode : each release of Stella seems to get harder and harder.
I have to fight to force myself to get ready for release time,
and when it comes, there always seems to be something popping
up at the last minute. This time, it's crashes on various
iMacs that I just got access to (while everything is working
perfectly on my Macbook Pro). I sometimes think it's time
to throw in the towel, and move on to other things ...
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2014 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
Updated all remaining issues with the documentation and
changelog, and bumped the version # to 3.1.

The file selector in Windows now ignores all items starting with '.', not just the directories '.' and '..'. This is most apparent when using the Windows port and browing Linux shares, which shows many dot files.

1) the interval between snapshots can be configured within the
'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.

key. This enables automatically taking snapshots every X seconds
while in emulation mode. The interval (in seconds) can be set
with the 'ssdelay' commandline argument.
Some minor cleanups to the EventHandler methods, making them
const when possible.
Added latest DPC+ changes from Spiceware.
Fixed issue with ROMs that run entirely from ZP RAM; no disassembly
was being generated when entering the debugger. For now, this
special case is detected, and the disassembly is generated for
the code that ran before the PC entered ZP RAM space. Eventually,
this will go away when the Distella fully supports disassembling
below 0x1000.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2009 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba

informs the rest of the system about how a page of address
space is to be treated (READ, WRITE, READWRITE). This makes it
much easier to track if a read from the write port has occurred.
As such, the _rwport command should now be somewhat faster.
Eventually, the debugger/disassembler will use this info to
colorize the output.

1) Removed all references to FBO in OpenGL. I won't be taking this
path, and will wait until SDL 2.0 integrates it directly. In fact,
most of the OpenGL TV filters will disappear in the next release, to
be replaced with Blargg NTSC filtering.
2) Defined the remaining color constants in OSystem.
Re-added showing the results of parsing debugger script commands
in the prompt.

state files will no longer work.

to 'resolvedata', since that more accurately describes what it does.
Also, it now accepts arguments as strings (never, always, auto)
instead of 0, 1, 2.
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.

The descriptions for the debugger commands are more streamlined
and better explained, and are neater when output.
Added 'cls' debugger command, which actually isn't for the debugger
at all, but for the prompt. This erases all showing text and history.
Removed 'bank' debugger command, since it was already removed from
the RomWidget UI.
Removed 'listwatches' debugger command, since it wasn't implemented
anyway. Besides, any watches are printed on every command access,
so it was pointless to have another function to do it.
Removed 'poke' debugger command; 'ram' and 'rom' do the same thing.
Fixed bugs in 'function' debugger command; it now correctly adds
functions without crashing. Related to this, added 'listfunctions'
and 'delfunction' debugger commands for user-defined commands.
Fixed bug in completions for functions; it was including user-defined
functions twice.
Some general code cleanups in DebuggerParser (use ostringstream
instead of constantly creating new strings) and Expression
classes (make some methods const, for safety).

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.

Changed 'basedir' location of OSX port to
'~/Library/Application Support/Stella', which is more in line
with Apple guidelines (not to mention it's not a hidden
directory, so it can be seen in Finder).

It doesn't look this is ever going to be resurrected.
Tab completion results in the debugger prompt widget are now sorted.

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).

forget exactly what's changed.
Fixed bug in Distella in handling relative addressing. Wraparound
was potentially occuring on a 32-bit integer, which caused a crash
when accessing a 4K array.

Partial cleanup of the debugger 'help' command, making the output line
up a little nicer. More work is required in this area.
Fixed bug in EditableWidget; setEditString now implies that editing will

when their address space has been modified by poke. Any writes done
inadvertently by reading from the write port are also flagged. This flag
is used by CartDebug to determine if cart address space has changed.
For now, it uses this information to do a complete re-disassembly.
Entire bank changes are signaled by setting myBankChanged to true,
which overrides the page dirty flag and short-circuits testing for it.
Still TODO is add support for 'AR' bankswitching, and fix the patch
method for several schemes.
Added latest DPC+ updates from Spiceware and Batari.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1976 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
whether the range 0x1000 - 0x1FFF (aka cart space) has been modified, and
if so, it forces a re-disassembly. Still TODO is modify all the cart
classes that manually handle poke operations to set the page as dirty
when a write actually succeeds.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1974 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
The idea is that all direct-access pokes will set a flag indicating that
the page containing the poked address is set to be dirty. Devices that
handle their own pokes will have to be updated to set this dirty flag too.
Overall, the point is to enable the debugger to know whether cart space
has been modified, and use that knowledge to selectively do a
re-disassembly.
