break. First thing to do is update the year. Happy new year to anyone
reading these commit logs.

the CPU registers (A/X/Y/PS) on ROM load.
Added 'INTIM Clks' to the debugger I/O tab, showing the number of clocks
before the current INTIM value decreases by 1.

state of the registers and messed up further emulation.

Removed various 'Image' and 'Greeting Card' ROM info from the database;
the info was incomplete, and there's no way that I'm going over 7000+
ROMS to add them all. Eventually, I'd like the database to be for valid
ROMs only.

of the RIOT chip. This flag is related to the edge-detect circuitry, and
set on active transition of PA7 pin, cleared upon reading from TIMINT (but
only *after* its result is included in the TIMINT read).

all aspects of the M6532 chip that a real 2600 console doesn't use.

these aren't fully activated yet, but they're the next thing I plan
to work on.

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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2318 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.

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.

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.

'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'.

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.

The license file is actually named 'License.txt', not 'license'
The 'Stella Team' has a capital T, not lowercase.

class reworking. Serializer class now handles read/write of state from
files as well as in-memory streams. As a result, Deserializer class has
been removed.
Added state rewinding to the debugger. For now, this is limited to 100
levels of undo, with a new state generated each time a step/trace/frame/
scanline advance is performed. The undo level is 'rolling', in that it
remembers the last 100 levels (so you lose the oldest states when you
start adding more than 100). For now, this is tied to the 'Alt-r' key
in the debugger. Still TODO is add a button for it, and clean up some
TIA output issues when rewinding.
Added support for 6K version of Supercharger ROMs (this fixes issues
with the 6K version of Cubis).
Cleaned up the Serializable infrastructure, making sure that all
classes that need to implement it actually do so now.
Fixed issue with editable widgets in the UI, where pressing Enter
on the keypad wasn't actually being registered.
