Added infrastructure to System and Device classes to deal with CodeAccessBase
even when the bankswitching scheme bypasses the normal System::PageAccess
way of reading ROM space. This allows bankswitching schemes 2E, AR, FE and
4A50 to support emulation core 'hints' for more accurate disassembly. The
only scheme not supported now is MC, which isn't really working anyway (I've
never actually had a test ROM for this scheme).
It's getting close, folks ...

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

tired of doing it manually every time it changes.
Tweaked the handling of JSR, RTI and RTS commands, so they don't erroneously
mark associated addresses as CODE when in fact they're never actually
executed.
Several parts of the Distella code were marking areas as DATA, even though
it depending on knowing the values for the X and Y registers (which it
doesn't, as it's a static analysis). As such, these areas are now marked
as ROW instead, since that's as precise as a static analysis can do. The
processing blocks are left there, though, in case Distella is improved in
a future release.
All the above changes allow for better disassembly with less
'false positives' (ie, areas marked as CODE or DATA when they really aren't).

I suspect there are other places in the core where this is being done,
so I need to go over the entire M6502.m4 file again.
In Distella, when tentatively marking an address range as CODE, stop
when encountering the first address marked as DATA/GFX/PGFX by the
emulation core. This is required since Distella will happily disassemble
CODE as far as possible, but addresses specifically marked as
DATA/GFX/PGFX obviously indicate the CODE range is finished. This is
also why it's so important to correctly mark areas as DATA; the
Distella algorithm depends on accurate information to know when to stop.

in a consistent way. Directives set manually have top priority, then the
results from a dynamic analysis (aka, from actually running the code), and
finally from a static analysis (aka, Distella itself).
Sometimes Distella will mark a section as CODE even if it hasn't been
marked as such dynamically. This occurs after a relative branch, which
Distella has no idea how to evaluate. It's possible that the code will
be executed eventually, but also that it will never be executed. As such,
these lines are marked with a '*', indicating that disassembly results
are tentative. If you get weird looking disassembly for these addresses,
it's probably a hint that it isn't really code at all.
PC addresses in the disassembly labels are now aligned with labels, and
shown in a lighter color. These can still be toggled on and off.

to the emulation core. That is, if something is determined to be CODE in
Distella and *not* in the emulation core, then it shouldn't be marked as such.
Note that the disassembly will still show it as CODE; it's just that the core
will not. This fixes issues with manually specifying directives from the
debugger prompt, whereby setting a directive and later turning it off never
actually turns it off (as it was being permanently set).

the code can then choose whether to use them, if desired. This fixes a bug

were zeroed if they resulted from addresses below $1000.

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.

allows gives much more informative disassembled outout.

on block, colour, etc). Also requires testing to see if this slows

done, and all related operations are completely #ifdef'ed out (resulting
in no extra speed/memory usage at all).

LDA/LDX/LDY, and marking them as GFX during a zero-page STA/STX/STY.

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.

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.

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.

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

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.

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 :)

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

present, and it properly loads and presents events from settings.
Still TODO is implement saveConfig(), to send the new events to EventHandler.
Modified ContextMenu/PopUpWidget to honour the 'mwheel' setting when
scrolling with the mouse wheel (previously, it always scrolled at 1 line
at a time).
Updated OSX project files for recent ComboDialog addition.

on AtariAge. It seems the documentation regarding port B is incorrect.
Pins previously defined as input/read-only *can* in fact be set as output,
which are then overridden if the console switches are pressed.
Or at least that's my understanding of it; I'm not entirely sure if this
is correct or not.

these bits were ignored, and treated as high all the time. A recently
reported Stella tracker posting noted that these bits could be
configured by SWBCNT to be input or output, and hence used as 3 extra
bits of storage. This is now enabled. Because of these changes, the
state file format has also changed.

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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2084 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
Fixed compile error in Zlib for Windows; unistd.h is not (normally) available on the Windows platform.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2082 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.

smaller than 640x480. Basically, the only way to use smaller modes is
on systems that report their desktop to be smaller than 640x480, or by
using the maxres commandline argument to simulate the same thing.

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.

window mode. Using modes smaller that 640x480 should now work in
all cases when using the 'maxres' commandline argument. Also, the
lower limit of 320x240 is now strictly enforced in all cases.

are multiple normal events that are called in sequence. The
infrastructure is in place to use these events, and they're
loaded/saved in the 'combomap' commandline argument. Still
TODO is add a UI to edit the events (manually editing the
config file is really tiresome).

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.

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.
Fixed bug in prune_snapshots script; it now properly handles directory
names containing spaces in both Linux and OSX (and probably Windows as
well, but this hasn't been tested).
Updated built-in PNG library to the latest version (1.4.3).

events that were set previously.

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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2063 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2059 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.

I look through the options.

systems where gettimeofday doesn't exist. Basically, the functionality
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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2056 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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
milliseconds at most). The appended value is an 8-character hex
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.

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.

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.

(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.

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 ...
