- changed from templates back to inheritance (sorry DirtyHairy :))
- added 'tsense' commandline argument and associated UI
- updated docs and screenshots for new functionality
- An extraneous TAB key event was being generated
- This is possibly an SDL bug in Linux only; it doesn't happen on other systems
- I've contacted the SDL mailing list for more info, so this code may be temporary
until after an instruction was executed. Also, toggle-able widgets
(pixel and bits) in the debugger can now be toggled with a single
mouse click, not a double-click. These fix issue #15.
This is enabled in the UI or through the 'tv.phosphor' commandline
argument. Note that what was previously 'tv.phosphor' (for setting
the blend level) is now 'tv.phosblend'.
Updated documentation in various places.
Added new 'tv.phosphor' commandline argument to accomplish the above,
and associated UI item in Video Settings.
Updated docs for 'tv.phosphor' and 'tia.debugcolors'. More work is
needed on this, since I need to add screenshots for this new functionality.
the fixed debug colors to user-defined preferences. Note that there
are 6 registers (P0,M0,P1,M1,PF,BL), and the option takes a string
of 6 characters, where each represents a colour for the respective
positional register (ROYGBP are the choices).
I may add a UI item for this, but this is as far as I will go with
allowing user editing.
to work like the old 'm' versions, so they work on all mirrors and
also allow one to enter a range of values to trap. Added more
stringent error checking for parameters.
- 'cls' now only clears the screen, and not the command history
- 'help' accepts another command as an argument, to give more info
about the command (ie, help breakif is now valid)
- command completion now works on built-in functions and pseudo-ops
file. For most people, that means the files are now stored in
'~/.config/stella' instead of '~/.stella'. Manually moving the directory
will be necessary if you wish to keep the old settings.
that the register held values up to 255 (when it should only contain 0-159).
Thanks to Omegamatrix for the report and fix.
On another note, I hope to get back to Stella development soon; it's been a
rough time since the last release.

For now, only the Paddle class is modified. Still TODO is add the

Added shortcut key to toggle TV scanline jittering, and have it default
to off. I'd really like to enable it again eventually, or perhaps use some
of the code in the case where scanline jumps are *really* large (since it

For FSNode read, change 'uInt8[]' arrays to BytePtr, which is an alias to

Added a specific closeConsole method, since the test for hasConsole was returning

number.name convention (which seem to be pass #'s for DASM). Initially
having this info in Stella was simply visually inconsistent, but now
it also interferes with recompiling when saving the disassembly (IOW,
the data put into the symbol file by DASM can't be fed back into DASM
again in these cases).

Once a frame has started, it means a new frame should be added. This
fixes a bug in the debugger UI whereby the frame count showed the previous
value, since sometimes you could enter the debugger (with a cond BP)
before the end of the frame was technically reached.

bases into a Common::Base class. Previously, this functionality was
spread across several classes, and used different approaches to formatting.
While the code still mixes C++ streams and C-style sprintf's, at least
it will now be easier to modify it all in one place.
Related to the above, added ability to use upper or lower case
characters for HEX output in the debugger. This is toggled by the
new debugger prompt command 'uhex', which is also tied to a new
commandline argument, 'dbg.uhex'.

All DataGridWidgets (ie, most of the inputs in the debugger) have more
strict input filtering, allowing to use $,#,\ specifiers for different
bases, as well as restricting input based on the specifier used (ie, if
you've entered a '\', only '0' and '1' are allowed, etc).

selection widget to a display of current bank state, taking into
account the more esoteric bank schemes. Currently, some functionality
is disabled/removed for now; I'll work on this for the next commit.
The format for displaying disassembler GFX/PGFX (binary or hex) is now
obeyed in the disassembly file output as well.
Changed various comments/enums/etc referring to 'preliminary' code to
'tentative' code, matching the actual intended meaning and the current
documentation.
Small API change for EditTextWidget; changed method name to setText, since
that's what I keep typing for some reason.

Fixed bug after pressing Enter/Return in EditTextWidgets; it was exiting
from edit mode, which locked out certain key handling (these widgets
are always editable, and should not be exited in such a way).
Also, I just noticed the changelog file is exactly 2600 lines long :)

- RIOT/TIA mirrors are now used whenever possible. This includes *all*
possible mirrors in the entire 64K address space. This was needed to

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

version.

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

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

decision is final. It's time to move on, folks.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2511 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
Distella '-r' option (Relocate calls out of address range) to
the disassembler core. Also added UI item to dynamically
change the setting.
Renamed 'resolvedata', 'showaddr' and 'gfxformat' commandline
arguments to start with 'dis', indicating that they're part
of the disassembler.

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

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

instead of the entire area. This fixes the speed regression from 3.6,
since the main TIA texture is now larger than before. Previously it
was 160 pixels wide out of 256 total (rounded to power of two), now
it's 560 wide out of 1024 total. In 3.6 it was updating a buffer 256
pixels wide, in the latest beta releases it was sending 4 times as
much data (256 -> 1024). Now it sends only 160/560. Similar
improvements happened with the height as well (210 lines vs 256).
On my test systems at least, this is an extremely large win,
resulting in similar speeds as 3.6 even though we've moved to a 32-bit
framebuffer.
Bumped version # for next beta release.
Pushed release date to June 1, to make absolutely sure I have
everything fixed and ready to go.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2493 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
now load and play test ROMs, complete with emulation of timing delays
due to slow accesses on real Harmony hardware. Still TODO is the tunes,
DPC+ stuff, which is stubbed out at this point.
Fixed bug in EFSC bankswitching; state files didn't contain extended RAM
information.
Cleaned up the Serializer API, resulting in slightly faster operation
and smaller state files. Because of this, the state file format
has changed for this release (old state files will no longer work).
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2487 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
instead of having different keys to turn them on and off separately.
This brings the functionality in line with the rest of the objects/
collision key-combos, which were also toggle-only.

fixing bugs too numerous to mention. The end result is that using
Control-0 to switch between mouse modes is much more understandable.
Updated properties database for Telepathy ROM, which now uses the
MindLink controller. Also updated Astroblast ROMs to use paddles
by default.

Bumped version number, so we start all over again.

normal control functions (ie, pressing Ctrl-q will not quit, but send
this combo directly to CompuMate).
Mapped Func-Space to the Backspace key for CompuMate keyboard.
Func-space (which is actually Ctrl-space is still supported).
Updated documentation for CompuMate changes and system requirements.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2418 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
z26 code never actually implemented this, so I'm not sure how people
actually entered Basic code. I guess not many people have played
with and tested this before.
Added more sensible keys for the CompuMate 'space' and 'enter' keys.
They're still mapped to '/' and ';' respectively (to keep locations
on the keyboard the same), but are also mapped to the actual 'Space'
and 'Enter' keys (to make usage much easier). I'll probably also
map 'Shift-;' to Backspace as well.
Updated documentation for CompuMate emulation.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2415 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
shifted keys from the keyboard. Most control-keys are
supported too, but still TODO is allow the Control key to
pass to the CompuMate controller and not pre-process it
by the EventHandler (so pressing Ctrl-q) shouldn't quit
emulation in that case).

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

Tweaked the format auto-detection by also looking at the TIA scanline
at which drawing first occurs.

when it isn't needed. According to SDL this shouldn't be necessary, but
some combinations of video modes and audio hardware cause sound to stop
working if it's repeatedly opened and closed. So we have to keep it open.
Always attempt to use 2 channels (aka stereo) when opening the SDL audio
device. This is now required, since ROMs can request mono or stereo mode,
and the sound system can no longer be closed and re-opened with the
desired settings. So we need to always use 2 channels to accommodate
when it might be needed. This actually more closely emulates the 2600,
which does have two audio channels. The 'mono' vs 'stereo' ROM property
basically controls whether these channels are exposed (ie, does the
virtual console have two-channel audio hardware installed). In that sense,
these settings control how the channels are mixed.
Updated some settings to have more reasonable defaults.
Added acknowledgement for people that have donated hardware to help with
development.

saved per device, so that unplugging and replugging a joystick won't cause
the previous mappings to be lost.
All attributes of a joystick (ie, number of sticks, number of axes, buttons,
hats on each stick) are dynamic, meaning that hardcoded values are no
longer used, making the handling more robust.

desktop on OSX and Windows, and the home directory in Linux.
The associated commandline has been changed to 'snapdir'.
Added 'GL VBO' toggle button to the Video Settings UI, and in
general cleaned up its interface.

Blargg NTSC filtering, but we need to revert to base functionality first.
Cleaned up the debugger API wrt converting values from integers to strings
(and vice-versa). There is now only one method for each of these functions,
rather than several ways to do so. In the process, convert from unsafe
sprintf functions into snprintf (eliminate potential buffer overflows).
The debugger 'print' command now indicates if any assigned label represents
a read-only location (R), a write-only location (W), or a read/write location
(R/W).
Fixed bug in DataGridWidgets (used in debugger ROM and CPU registers), where
scrolling the mouse-wheel would cause a segfault. Scrolling the mousewheel
now changes these items as expected.

contents. The file was being accessed and read, but the commands it contained
weren't being executed! This bug appeared in April 2010, so it looks like
not many people are using this feature (or at least they're not reporting it).
Cleaned up a few compiler warnings in DebuggerParser class.
Bumped version # for beta release.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2254 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba

digital, hat and keyboard input.

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