To anyone reading this, Merry (belated) Christmas and Happy New Year!

a class more generic, but when it's never used, all it does it slow
things down.

Some code cleanups; add const and optimize some methods.

*always* pass in 0,0,0 for the various bases, it is redundant to pass that
data in on each invocation. So now the c'tor does it automatically.

reading these commit logs.

we need to modify what is caught. Ironically enough, this fixes
a bug whereby when certain errors occur, the recovery system
itself would crash, not the issue that actually caused the bug!

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).

these logs!
Moved TODO and Credits info directly to the webpage, where it will hopefully
be easier to maintain.
Fixed 'crackling' sound when loading a new ROM, introduced with the 3.5
sound restructuring. It looks like stale data was being loaded by the
sound processing callback. As well, moved the computation of certain
division variables from the sound callback to the framerate re-calculator
(where it's recomputed 1/5 of the time or less).
Updated AboutDialog with info about Stella DonationWare status, and active
members of Stella development.
Updated OSX in-app HTML documentation about Stella DonationWare status.
Bumped version # to 3.5.1_svn, and the process starts again.

console (which doesn't exist on every platform). Also use proper C++
stringstreams instead of C-style arrays (which are evil). If an exception
is thrown, start the debugger with a fatal error message. Currently, this
message is simply printed in the debugger info window. Still TODO is add
a dialog to show the entire input from within the UI, as well as a way
to exit the ROM when a fatal error occurs.
Cleaned up the API a little, adding explicit declarations for when a method
can throw an exception. Also merged some empty classes directly into their
header files.
Added functionality to the System class for querying whether it has
been reset while in 'autodetect' mode. Autodect mode is defined as
when Stella starts and temporarily runs to autoconfigure itself.
Some classes (such as Thumb ARM emulation) need to know this, and
suppress debugging output/throwing exceptions when not running in
normal emulation mode.
I hope to have a new release done by the end of this week, or the end
of the month at the latest.

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 ...

values instead of 16-bit.
Fixed compilation of System class and M6502 disassembly tracking when
compiling without debugger support. In this case, the tracking is not
done, and all related operations are completely #ifdef'ed out (resulting
in no extra speed/memory usage at all).

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.

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.

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.

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.

'Stephen Anthony' (aka, me) in addition to Brad Mott as copyright
holders for Stella. I think I've been with the project long
enough now (almost 10 years) to justify being specifically mentioned
above and beyond 'the Stella Team'.

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.

from the write port. Basically, the cartdebug class depended on the
console existing, but it wasn't being created until after it was required.

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.

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.
