stephena 37d9c6c99f Converted from C-style 'typedef' to C++ 'using' where appropriate.
I find the newer syntax more readable, since it acts exactly like
an assignment statement.

stephena 29fe39dd99 Made M6502 own all breakpoint/trap info instead of sharing pointers to
it with the debugger (this eliminates more new's and empties another d'tor.

Re-wrote PackedBitArray to use a bitset instead of home-made code.

stephena 7b9169c18d Convert all arrays in the codebase to vectors, so that we get all
the advantages of C++11 (move semantics, list initialization, etc).
I'd hoped to somehow wrap a vector behind Common::Array and not have
to change the codebase to this extent, but it didn't work out.  And
I've since read that it's bad form to extend from std::vector anyway.
This is *THE LAST* bit of work I'm doing with arrays; everything is
now a proper vector.

stephena 740eeed579 You know what's better than adding move semantics and initializer
lists to the Array class?  Completely deleting all that code and
using a std::vector directly :)

stephena 2f4a3e7966 Cleaned up the Cartridge::bankXXX API. Carts which are non-bankswitched
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types, and is obsolete now that the UI allows to change banks for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.

stephena 12e727ae4e The 'savesnap' command in the debugger prompt now actually saves a
snapshot of the TIA image, including partial rendering (if applicable)
and scanline indicator.  Previously it only saved the TIA image, which
basically made it useless from the debugger POV.

stephena 95fe213f3a Consolidated the code for converting integers to strings in various
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'.

stephena f533fcad34 Some cleanup of dead code, and changes to the file I/O in the debugger.
For now (and the next release), filenames are hardcoded to sane defaults.
Eventually, the code may be extended to use BrowserDialog to query the names,
but it's taking much too long to get working, and I want to get a new release
done before the end of May.

stephena c95d5f804d Updated all files to copyright 2012. Happy New Year to anyone reading
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.

stephena 40a66edee4 Cleaned up usage of sprintf in the codebase, changing to
BSPF_snprintf instead, which should eliminate any potential
buffer overflows.  Also moved from static arrays to stringstreams
where appropriate to make things safer and more C++ like.

stephena 377765f565 Removed all traces of the OpenGL TV filters. This is due to be replaced by
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.

stephena df71aa03d1 Cleaned up the FilesystemNode API a little, removing some redundant code.
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.

2011-06-09 14:00:30 +00:00
stephena bc7daa397e Added ability for the debugger to start up in 'fatal error' mode.
This basically shows a messagebox as soon as the debugger starts,
describing the error and offering the choice to continue debugging
or exiting the ROM entirely.

The DPC+ code now catches fatal errors from the Thumb ARM
emulation code and shows it as a fatal error in the debugger.
This means you no longer need to look at the commandline for
this output, and you immediately know that something has
gone wrong.

Added 'exitrom' debugger parser command, which completely exits
from the debugger *and* the ROM, going back to the ROM launcher.

Cleaned up the API a little, rearranging some classes and
adding references instead of pointers.  More work to be done
in this area.

2011-05-26 16:14:46 +00:00
stephena 5025a21d92 Updated Thumb ARM emulation to log its output instead of printing to the
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.

stephena 4e6d4cb1c6 Cleaned up some inlines that weren't needed.
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.

stephena 7411867290 Decided to take a little break from the debugger stuff, and clean up
the various header files.  Basically, I'm following advice from
Effective C++, and including only what's absolutely necessary.  For
definitions that don't need to be included, the designation 'class xxx'
is used instead.  This could potentially lead to faster compile times.

stephena 5624d30d93 The emulation core now tracks access to DATA areas (currently, any address
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.

2010-10-10 20:24:22 +00:00
stephena 5fe91e2841 Greatly improved the disassembler output, but having Stella keep track of
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.

stephena 8f68c677d4 Added commandline argument 'gfxformat', also accessible from a right
mouse button context menu in the disassembly listing.  This is used to
set the default display format for GFX data sections (currently, binary
and hex are supported).

Fixed bug in several debugger input areas to accept the '\' symbol.
This symbol is needed when entering data in binary format (it must
prefix the data if the default base for that field isn't binary).

Added 'jump' debugger prompt command, used to scroll the disassembly
to the given address (or there-abouts, if the address isn't valid).

Editing data in the disassembly now won't cause the display to jump to
the current PC.  The display will only move to the PC when it actually
changes.

stephena 6faa9b4b69 Several fixes across the board for better functionality in 'small'
window mode.  Using modes smaller that 640x480 should now work in
all cases when using the 'maxres' commandline argument.  Also, the
lower limit of 320x240 is now strictly enforced in all cases.

stephena a2ca2730c1 Cleaned up some more FIXME and TODO:
1) Removed all references to FBO in OpenGL.  I won't be taking this
path, and will wait until SDL 2.0 integrates it directly.  In fact,
most of the OpenGL TV filters will disappear in the next release, to
be replaced with Blargg NTSC filtering.

2) Defined the remaining color constants in OSystem.

Re-added showing the results of parsing debugger script commands
in the prompt.

stephena b781611925 Some updates to the PromptWidget and DebuggerParser.
The descriptions for the debugger commands are more streamlined
and better explained, and are neater when output.

Added 'cls' debugger command, which actually isn't for the debugger
at all, but for the prompt.  This erases all showing text and history.

Removed 'bank' debugger command, since it was already removed from
the RomWidget UI.

Removed 'listwatches' debugger command, since it wasn't implemented
anyway.  Besides, any watches are printed on every command access,
so it was pointless to have another function to do it.

Removed 'poke' debugger command; 'ram' and 'rom' do the same thing.

Fixed bugs in 'function' debugger command; it now correctly adds
functions without crashing.  Related to this, added 'listfunctions'
and 'delfunction' debugger commands for user-defined commands.

Fixed bug in completions for functions; it was including user-defined
functions twice.

Some general code cleanups in DebuggerParser (use ostringstream
instead of constantly creating new strings) and Expression
classes (make some methods const, for safety).

stephena 03191759ab More DiStella cleanups; the disassembly now properly uses peek() and dpeek()
methods from Debugger directly.  As well, the start address is now passed
into DiStella::disassemble() directly; decision to start from the reset
vector is done outside DiStella.  This is in preparation for starting
the disassembly from any valid address.

stephena 28114a8c51 OK, this is the first pass at a huge reorganization of the debugger
classes.  First off, the distella code has been integrated into a
DiStella class.  This code isn't yet tied to the debugger, but it does
at least compile and generate valid output.

The RamDebug class has been replaced by a CartDebug class, which
takes responsibility for the previous RamDebug stuff as well as 
things related to Cart address space (read from write ports,
disassembly, etc).

Fixed E7 bankswitching when reading from the write port in the upper
256byte area.

Fixed 'read from write port functionality' in general for all carts
that supported it previously.  Basically, if _rwport is enabled, the
address is checked to be an actual read (vs. one that's part of a
normal write cycle), *and* it's actually an illegal access (each
cart/bankswitch type now provides a hint to indicate this condition).

Still TODO is clean up the rework, properly integrate DiStella, and
fix labels and defines (which seem to be completely broken).

stephena e234139a3c Updated Stella headers in all files:
The license file is actually named 'License.txt', not 'license'
  The 'Stella Team' has a capital T, not lowercase.

stephena 33130a78f0 Updated 'Fixed Debug Colors' for PAL mode to more closely match the ones
in NTSC.

First pass at disassembly of ZP RAM in the debugger UI.  For now, the
entire range is disassembled, with no regard for alignment (so the PC
won't necessarily always line up with the disassembly).  Also, changes
to RAM don't yet trigger a re-disassembly.

don't add one when the console is first created.

stephena ddc77bd7e7 Added button for rewind to the debugger, next to the buttons which it
applies to.

Bumped version # to alpha3.

stephena 3c5cc40e08 OK, this looks like a huge update, but it's only because of some Serializer
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.

stephena 5e4b690d8d Well, it's finally here. First pass at the new TIA code, which improves
emulation when performing 'illegal' HMOVEs (aka, when modifying the HMxx
registers within 24 CPU cycles of HMOVE).

All tweaks for illegal HMOVEs have been removed; and all ROMs that
previously needed those tweaks are now working correctly.  Several other
ROMs are fixed as well, including Bumper Bash and Pole Position.

As this is WIP, there is also some breakage:

1)  Cosmic Ark 'TIA confusion mode' effects aren't complete; the
movement is correct, but the missile widths aren't corrected yet.

2)  Performing a write to NUSIZx while a player is still drawing
isn't complete.  This breaks several ROMs that worked before, such
as Galaxian and Space Instigators.

3)  Writes to RESPx aren't complete yet, especially if they're
combined with an immediate write to NUSIZx.

Most of the ideas (and some code) for these changes comes from
contributions to MESS and EMU7800.  Where applicable, permission
was obtained from the original author to use the code/ideas.

stephena 3280901be9 Added support for accessing/modifying extended RAM (aka SuperChip) from
the debugger RAM UI.  A scrollbar is now present, which can scroll
through each 128 byte 'bank'.  Labels indicate the current readport,
so you can distinguish between different areas of RAM.  For now,
F4SC, F6SC, F8SC, and FASC have been converted, but I'm looking into the
other schemes now.

The RAM UI takes care of all read/write port issues.  From the POV of
the UI, the RAM can be treated as zero-page; translation is done
behind the scene.  Searching/comparing and change-tracking are also
supported.

The 'ram' command in the debugger prompt now reflects all RAM, and
readport/writeport addresses are shown, making it easier to use the
command withot having to look up the offsets.

Debugger width has been bumped to 1050 pixels wide to accomodate the
new functionality.  We'll see how much trouble this causes ...
