Stephen Anthony c2302c2e71 Cart::getImage refactoring: use uInt32, since sizes are never negative. 2017-09-01 10:23:17 -02:30
Stephen Anthony 31907f4be1 More peek/poke refactoring, and improved comments in bankswitching schemes. 2017-08-31 13:01:45 -02:30
Stephen Anthony a5d9550f2f First pass at cleanup of the peek/poke API from Device class:
- remove peek and poke from classes where the addressing is set up such that they aren't needed
- where possible, move from using 'myCurrentBank << 12' everywhere, to precomputing the value (perhaps a small optimization, but still valid)

Stephen Anthony cd689941b6 Move to C++14, now that all the minimum required compilers support it.
Clang 3.8, gcc 5, Visual Studio 2017 and Xcode 8 are now the minimum
supported compilers, and they all support C++14, so we may as well use it.

 - Change all make_ptr to make_unique
 - Change iterator begin(), end(), etc to const versions where appropriate
 - Remove UniquePtr, since C++14 supports it natively

Stephen Anthony 9972af022a Fairly huge refactoring of the cart autodetection code.
This has been in patch form for about a year, and I'm finally
getting around to applying it.  Basically, we separate the Cart
class into 3 classes:
  - Cart: stuff specific to cartridge emulation
  - BSTypes: various bankswitch types, both as enum and strings
  - CartDetector: actual bankswitch auto-detection code

Also made more use of smart pointers, and added const in a few
more places.

I promise to get back to the phosphor stuff soon.  This is just
to clear my head a little.

stephena 883971985e Removed some redundant includes in various Cart classes.
Introduced Cartridge::initializeRAM() method, to eliminate duplicate
blocks of code in every bankswitch scheme that uses extra RAM.

stephena 1a09d37d1b Speed up accesses to System by using constants. It's fine to make
a class more generic, but when it's never used, all it does it slow
things down.

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types, and is obsolete now that the UI allows to change banks for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 ef183beab7 Slight cleanup of the System::PageAccess API. Since all c'tor calls will
*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.

stephena feac57253e Now that the Serializer class throws exceptions differently,
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!

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 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 b2ed949082 Some final changes for the 3.2 release, including documentation updates.
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.

2010-08-19 21:48:28 +00:00
stephena d007c3502f Several big improvements to the debugger:
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 :)

stephena 32aa9d3186 Fixed a *REALLY* annoying bug in Windows with the latest code. It seems that System::PAGE_xxx enumerations were already defined elsewhere in a Windows header file. This was very irritating to track down. As a result, they're now named System::PA_xxx (for 'PageAccess').
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.

2010-04-14 22:35:46 +00:00
stephena af8c5a5133 Added 'PageType' infrastructure to PageAccess, which basically
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

enough now (almost 10 years) to justify being specifically mentioned
above and beyond 'the Stella Team'.

as 'const', and return types are closer to the actual type of data
returned.

2010-04-02 22:09:31 +00:00
stephena 6fee79ddff Modified most of the cart classes to properly set the 'page dirty' flag
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.

2010-03-28 03:13:10 +00:00
stephena 2cc0d60940 First pass at adding 'hints' to each Cart class that its bank has changed.
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.

stephena 67fec652b0 Updated TIA code to emulate the 'widening' part of the Cosmic Ark
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 :)

2009-08-27 22:59:14 +00:00
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 5d29bc0e2d ROMs smaller than 2K in the Cart2K class are now mirrored correctly,
not by actually copying pieces of ROM, but by addressing different
parts of the ROM with an appropriate mask.  This fixes a patching
bug I just found, whereby patching one part of the ROM wasn't
propagating it to the rest of the image.

stephena 664d4e5d1a Fixed issue with incorrect reporting of OpenGL version number for Windows.
Because the version was always being returned as 0, the TV effects were
always disabled, even on hardware that could support them.

Creation of OpenGL video mode is now more robust.  If it fails for any
reason, fallback to software mode is now done (and a message stating
that it happened).  This still won't protect against the operating
system lying to Stella and saying OpenGL support is really available
when it isn't, though.

Added support for ROMs smaller than 2K.  These are still treated as
2K ROMs, but have their contents mirrored appropriately.

Bumped version number.

stephena 79e4e42ae7 OK, this is a BIG commit.
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.
