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.

Fixed bug in handling analog axes with jitter; they were overriding events from
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.

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 :)
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2098 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2031 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2016 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
Updated all remaining issues with the documentation and
changelog, and bumped the version # to 3.1.

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

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).
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1998 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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).

this. That's the main problem with long delays between releases; I
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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1990 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.

more sense, as it isn't a double-negative any more).
Made PropSet::getMD5() more explicitly return a boolean indicating if the
properties were found, vs. having a CartName of 'Untitled' indicating that
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.
Updated documentation for bankswitch types, more clearly indicating which
ones support autodetection and the debugger.

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
value.
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.
Thanks to Eckhard Stolberg for advice on the SCROM, and how to
modify it.

schemes that have multiples areas of RAM. Converted F4SC, F6SC, F8SC,
FASC to this new functionality.
Added ability to modify extended RAM in 3E, CV, E7 and EFSC ROMs.
Note that these ROMs can swap RAM in and out dynamically, so what
you see in the RAM area won't always be RAM.
Updated debugger CpuWidget; decimal and binary values for SP/A/X/Y
are now all shown at the same time (previously the registers had to
share a decimal/binary view).
Updated debugger documentation for recent additions.

git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1740 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.
