currently only shows the SWCHx and SWxCNT registers, but it will be
expanded to include all items currently shown by the prompt 'riot'
command.
Added SaveKey controller, which is basically an AtariVox without the
SpeakJet chip. The I2C code still isn't working (same as AtariVox).

behaviour after wraparound, which isn't sufficiently defined in any of
the documentation I've read. The new code works with all the ROMs I've
tested, but I still have the feeling it's a bit of a hack. More
research is definitely required.

and never noticed the problem :)

in evaluating the SBC opcode. Technically, the code does the same thing
in C++, but that was only a fluke :) Thanks to JLA for the bug report.

understand. Eliminated certains constants that I could never really
explain (like the 0x40000 constant from z26), and more properly emulated
the behaviour when going negative on the timer count (according to the
documentation).

functionality of the Debugger::riotState() method. It will become
more useful when I add a RIOT tab to the debugger. Also, added
change tracking infrastructure.
Fixed long-standing bug with viewing the contents of TIM{1, 8, 64, 1024}T
registers. Apparently, the output generated by the 'riot' debugger
command showed either INTIM or TIMINT for those registers, and not the
actual value written to those registers.
Added INTIM, TIMINT, and TIMCLKS to the riot output, which show the
current values of the timer, the timer interrupt, and the number of
'timer clocks' resulting from writing to a timer register.
Cleaned up some of the debugger API, removing pointers and using
references instead.

can't test it, because I can't get OSX to see the AVox on the systems
here at work.

to never write anything to the EEPROM data array. I'll have to speak to
Supercat about that one.
Rearranged controller stuff, and changed the API a little. Basically, I
eliminated pointers to System in the controller classes, so they'll
always have a valid system object.
The savegame screen in MGD now appears, indicating that we're reading
from EEPROM SDA correctly. Of course the score isn't being saved
properly yet.

used in the AtariVox and SaveKey. It isn't actually connected yet, and is
basically a C++ wrapper around the I2C routines provided by J. Payson
(aka Supercat).

'Mission Survive', 'Solaris' and 'Swoops!'. These are temporary hacks
until the new TIA code is written, which *will* be done before the next
major release. In fact, it might even justify a 3.0 release. Fixing
the TIA is my number one priority over the next few months.
Added debug code to the TIA class pointing out when object positions
are reset less than 24 cycles after an HMOVE (which incidentally is
the cause of most of the TIA emulation bugs). Simply uncomment the
DEBUG_HMOVE declaration at the top of the class to activate this.

bad, parity, stop bits, etc. Since the AVox is the only device using
this, and I don't see any new devices making use of it any time soon,
it doesn't make sense to over-engineer the class.
Added '-avoxport' commandline argument and associated UI setting to
set the serial port the AVox will use. I *was* thinking about
auto-detecting this, but apparently it isn't supported on all platforms.
Added AtariVox as a controller type selectable from the GameInfoDialog.

be losing it :)

new code seems to contradict some documentation on the timer behaviour,
but does work with all ROMs I've tested (it even fixes a few ROMs that
didn't work before). I'm not sure if the documentation is incorrect;
more testing and feedback is needed.
Bumped version number and documentation for 2.5.1 release.

Made SpeakJet emulation be optional, because it's still a WIP and we'll
soon be able to have AVox support without it.
Added SerialPort infrastructure, which will implement serial port access
in a general way. Those ports which don't wish to do so can simply not
implement a SerialPortXXX class; in that case a null SerialPort is used.
Still TODO is actually implement the serial port functionality for UNIX,
and add similar classes for OSX and Win32.

starts.

Made the default snapshot folder be $BASEDIR/snapshots, and got rid
of the previous default './'. I suspect this relative pathname was
causing a problem. The user is still free to choose another
snapshot dir, but the one in $BASEDIR is always created anyway.
Removed the logic that entering Stella directly from a ROM wouldn't
allow one to enter the ROM launcher afterwords. You can now always
exit from a ROM back to the launcher, no matter how Stella was
launched.

Fixed long-standing bug where debugger mode didn't work for E0 carts.
It seems at some point I refactored a section of code, and the debugger
wasn't being locked before entering it. Hence, bankswitching was
occuring when the debugger attempted to read the emulation state.
Fixed a similar debugger issue for 4A50 support. This might necessitate
a 2.5.1 release ...

Updated docs for impending 2.5 release. I still have to add documentation
for Rom Info and Rom Audit functionality. That's the worst thing with
adding new features; I have to document them :)

marked as being incompatible. With each future release, if the format
changes again, we simply update the header. Also, the header encodes the
last version that worked with that format, with 2 bytes per number (ie,
version 2.5, or 2.5.0.0, is encoded as 02050000).

it occurred to me to simply modify that font to be twice as large :)

people use this feature, since this problem was never reported before.
Some general cleanup of the Debugger API. I generally don't like
pointers, and use (const) references whenever possible.
