(Atari 2600) Stella 3.1 - 模擬器

2010.04.22

Stella release 3.1 for Linux, MacOS X and Windows is now available.

- Fixed a major bug with text drawing in software rendering mode.
Switching between windowed and fullscreen mode while text was
being shown could result in garbled text or even a program crash.

- Fixed issues when using 'sleep' timing, whereby a lockup could
occur when changing video modes, and/or Stella would consume
more CPU time than was necessary.

- Integrated Distella disassembler, completely replacing the previous
disassembler. The entire infrastructure has not been completely
ported yet.

- As a result, labels defined by the user or from a DASM symbol file
aren't actually used in the disassembly, and almost all distella
config options are disabled. These will be addressed in a future
release.

- Completely reworked the debugger cartridge interface, so that the
disassembly is dynamic (ie, the debugger tracks when cart address
space has changed, and automatically performs a re-disassembly).

- All carts with extended RAM that differentiate between read and
write ports now behave correctly when a read from the write port
occurs.

- Added more complete support for the more esoteric bankswitch schemes
in the debugger. These schemes now support accurate disassembly and
ROM patch functionality. Related to this, fixed a bug in disassembler
view when a failure to patch a ROM still showed the (incorrect)
patched results.

- Added ability to disable TIA object collisions, independent of
enabling/disabling the objects. Previously, one had to completely
disable an object to avoid collisions, but now an object can be
enabled (and seen) but still have its collisions disabled. These
actions are tied to the same keys as the enable ones, except the
'Shift' key is also used.

- Added preliminary support for 'DPC+' bankswitching scheme, thanks
to Darrell Spice Jr and Fred Quimby.

- Added '16in1' bankswitching scheme, which works with various ROMs
labeled '128-in-1 ...' (the database has been updated for these).
Related to this, switching between multicart ROMs for 2in1, 4in1,
8in1, 16in1 and 32in1 now shows a UI message indicating which ROM
is active.

- Reverted some of the TIA improvements with respect to 'starfield
effect' as seen in "Cosmic Ark" and "Stay Frosty". The emulation
is now more accurate as compared to the majority of consoles in use.

- Added debugger pseudo-register '_rwport', which traps on a read from
the write port. This differentiates from reads that are normally
part of a write cycle (ie, it traps only on inadvertent reads).

- Added 'resolvedata' commandline argument and associated UI item,
used to set the "resolve data sections" config option in Distella
(vs. treating all address space as code).

- Added 'runtopc' debugger command, used to step until encountering
the given program counter. This is also available in the ROM
disassembly UI from the right-click context menu.

- Added 'listfunctions' and 'delfunction' debugger commands to
access/remove user-defined functions. Related to this, fixed a bug
in 'function' command that could cause a program crash.

- Added 'cls' debugger command, used to erase the text and history
from the debugger prompt.

- Removed the 'listwatches' and 'poke' debugger commands, as they
were redundant.

- Removed the 'loadlst' debugger command and the ability to use a
DASM .lst file. This code was incomplete, and no longer fits with
the recent disassembler improvements. Support for this may return
in a future release. Modified 'disasm' debugger command to accept
a second argument indicating the number of lines to disassemble.

- Improved tab-completion in the debugger prompt; it now completes
on functions and pseudo-registers.

- Added emulation of the "Sega Genesis" controller, with two buttons
that are directly supported on a real system.

- The ZLib library is now included in the core code, so Windows
developers no longer have to track down the ZLIBWAPI archive.

- Many changes to the MacOS X port, bringing it more in line with
other systems:

* The application is now known as 'Stella' (instead of StellaOSX).

* Two versions are available: the first is a 32-bit Universal Binary
for OSX 10.4 - 10.6, and the second is 32/64-bit Intel-only for
OSX 10.6 (aka Snow Leopard). The Intel version is compiled with
the very latest compiler (LLVM/Clang), resulting in better
performance.

* The keyboard handling is changed to match other systems in terms
of where the keys actually are on the keyboard (ie, the OSX
Command key corresponds to Alt, and the OSX Control key
corresponds to Control).

* The application menu has been cleaned up and simplified, and it
now shows the correct shortcuts for menu items.

* The settings file is now (according to Apple standards)
'~/Library/Preferences/net.sourceforge.Stella.plist'.

* The base directory (where all other Stella stuff is located) is
now '~/Library/Application Support/Stella'.

* Because of these changes, all your settings will have to be
entered again.

- Added 'ctrlcombo' commandline argument, which toggles the use of the
control key as a modifier key. This is useful if you want to press
'Control' and 'R' in a two player game, and not have the combination
treated as 'Control-R' (which will issue a ROM reload).

- Added 'usemouse' commandline argument and associated UI item. This
toggles the use of the mouse as a controller of any type.

- Added 'uimessages' commandline argument and associated UI item.
This toggles showing of UI messages overlaid on the screen. Critical
messages are still shown, though.

- Added ability to take multiple snapshots in a given interval every
x seconds.

- This is currently tied to the 'Alt-s' key and is not remappable
(for now).

- The interval can be set with the 'ssinterval' commandline argument
and within the UI, and defaults to 2.

- Many changes to the FrameBuffer and UI code for 'smaller' systems.
Stella will now scale correctly to small screens, down to 320x240
(which is the absolute lower limit supported). Related to this,
added 'maxres' commandline argument, which is useful for developers
testing on such systems.

- The About dialog now shows the version of SDL in use, and the type
of CPU the application is running on (i386, x86_64, etc).

- Improved 'listrominfo' commandline argument to list all information
from Stella's internal ROM database, including a heading. This
output can be imported into a spreadsheet or database program.

- Renamed 'tiafloat' commandline argument to 'tiadriven'. The
emulation of the behaviour of floating TIA pins is also much
more accurate.

- Reworked state files so that they're associated with the cartridge
type used, not the MD5sum of the ROM. This is useful for developers,
since the same state file can now be loaded from different ROMs, as
long as the cart type stays the same. This also fixes a bug where
loading from a non-existent state file could cause Stella to crash.
Because of these changes, old state files will no longer work.

- Fixed bug in certain editable text fields, where pressing
Return/Enter would disable any further input.

Have Fun!
