Finally decided to stop fighting C++, and just use size_t everywhere an
array is used.
Even though this is a 64-bit value, it seems that C++/STL expects it
when dealing with arrays, so I guess we will too.
Converted many C-style arrays to C++ std::array. In the process, cleaned up a lot of magic constants.
Replaced most C-style memset/memcpy operations with C++ equivalents: std::fill/std::copy.
std::copy in particular fixes a few potential bugs, since it operates on the datatype size,
and not just on raw bytes.
- Removed System::PAGE_SHIFT from all classes (except where it's needed inside System); it is an implementation detail of that class that shouldn't be used outside the class, and was making the various calls to setPageAccess very messy
- Changed uInt32 to uInt16, and loop variable to 'addr' for all calls to setPageAccess; this is for consistency, and allows the reader to see how all the code is similar in different classes
- Updated comments in various places (mostly TIA and RIOT) to more clearly show how page accessing works.
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.
Introduced Cartridge::initializeRAM() method, to eliminate duplicate
blocks of code in every bankswitch scheme that uses extra RAM.

std:: functions into BSPF namespace at all. So I removed them, and have the
calls map directly to the std:: versions.

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

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types, and is obsolete now that the UI allows to change banks for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.

*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).

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.

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.

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.

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.
