or those which implement their own unique scheme no longer have to
implement bank and bankCount; this base class versions will be used
instead.
Removed the debugger 'bank' command, since it didn't work for all cart
types, and is obsolete now that the UI allows to change banks for
all cart types.

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).

Updated all bankswitch schemes for potential buffer overflow
issues. Copying was being done without regard for the size of the
ROM buffer.

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
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 ...

disassembly listing) to show/hide opcode/instruction addresses.
The disassembler now includes hints from current PC location *and* 'code
access points' from the emulation core. Testing has shown that some ROMs
don't show completely accurate disassembled output unless both options are
used.
Updated most of the remaining bankswitch schemes to use the new 'code access
points' functionality during disassembly, allowing for very accurate
disassembled output. Note that the more esoteric schemes (AR, 4A50, FE, MC)
are supported for now.

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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2138 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.

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 :)

now properly detected as E7.
Some minor cleanups to the Cart classes.

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.

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.

or rewind command.
Updated 'FE' bankswitch scheme to the new disassembly infrastructure;
it now properly indicates that it has two banks, and keeps track of
when the bank changes.
Some cleanups to CartXXX classes; most methods didn't need to be
virtual.

This is very useful for conditional re-disassembly, since many bankswitch
schemes consist of ROM only, and once disassembled, cannot possibly have
a different disassembly at some later point. This is mostly done for such
static schemes (2K, 4K, etc), but more work is required for carts with
extended RAM. Basically, the cart knows best how its been accessed, so
it makes sense to have the hints there.

handling to C++ stringstreams instead of C-style character arrays,
which fixed some segfaults (sprintf is evil).
First pass at tying the number of banks to the disassembly. The idea
is that the startup bank (which is now identified by the cart) always
starts at address at 0xfffc, while the other banks are defined by the
PC at the first time we enter the debugger. This is still a WIP,
since there's no actual checking done yet to see if the current PC
is in the current disassembly.
Added 'ctrlcombo' commandline argument, which completely disables
checking for Control-x key combos. This is useful when playing
2-player games where the 'f', 'r' and 'Control' keys are supposed
to be treated separately. Previously, pressing Control and 'r' or
'f' processed some other action (change framerate, reload rom, etc).

starfield effect. More research is required in this area.
Large update to exception handling throughout the codebase. It seems
that in many cases, the correct 'catch' block was never being called.
I never see exceptions thrown very much, so that area doesn't get much
testing. But I guess it's good that Stella doesn't generate many
exceptions :)

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.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1849 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
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.

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.
