(Atari) atari++ v1.80 - 模擬器

2015.11.10

The Atari++ Emulator is a Unix based emulator of the Atari eight bit
computers, namely the Atari 400 and 800, the Atari 400XL, 800XL and 130XE,
and the Atari 5200 game console. The emulator is auto-configurable and will
compile on a variety of systems (Linux, Solaris, Irix).

Atari++ v1.80 Changelog:

a new release of Atari++, the portable atari emulator for Linux and windows
has been released here in the download section - as usual, you find there the
Linux sources and a compiled version for 32-bit Windows. Release 1.80 is a
new major release of the Atari emulator, not only fixing a series of nasty
bugs, but also including new features and major improvements. The major
improvement is the inclusion of a Basic interpreter, named Basic++, which
improves on Atari Basic in many ways.

Atari++ has now a built-in Basic interpreter, namely Basic++. It is a mildly
extended Atari Basic dialect, which is quite a bit faster, plus one
additional command, "DIR". See the Basic++ distribution for additional
modifications.

The Basic settings have been improved, the preferences allow now up to three
Basic images to be defined, typically corresponding to revisions A,B and C of
the language.

The CPU emulation fixed the cycle count for some rarely used instructions.
Added a profiler to the monitor. PROF.S starts the profiler. PROF.L lists the
profile counts collected so far, PROF.C lists the cumulative cycle counts of
subroutines.

Tape emulation has been largely extended and simplified. Entering a non-
existing tape will now create an error immediately. The tape emulation also
allows now WAV files, i.e. digitized real tapes, and will decode them on
demand. Output to .WAV files (audio-encoding) is now also possible. This
integrates the wav2cas and cas2wav programs of the same author into the
emulator.

SIO sound emulation has been extended. The SIO sound now also emulates the
tape sound on input, and improves on the authenticity of the disk drive sound.
The X11 front end improves the handling of mouse clicks. Mouse clicks that do
not go into the window but into an overlapping window are now ignored.

Audio outut can now be recorded into a SAP Record-Type R file for playback.
Disk drive emulation has been largely improved. Several drive types are now
emulated, including their serial transfer characteristics, such as disk drive
speed. Note that the original 1050 drive emulation no longer takes disks that
are double density or have more sectors than those of the original disk
formats. To play such extended disks, select one of the more advanced drive
types.

SIO emulation has been reworked to some degree to allow the extended drive
types, control the serial speed and allow for proper tape emulation.

Binary disk images now also create a valid disk structure containing the load
file as AUTORUN.SYS so it can be loaded from DOS, too.

The math pack patch has been revised and its precision has been inproved by
changing the rounding policy slighty. The floating point to ASCII conversion
now also follows the convention of the original math pack.

Detection of .BAS (Basic) files as disk images is now handled more carefully,
and the emulator will no longer confuse some xfd disk images with basic files.
The built-in monitor supports now symbolic labels. Such label information can
be read from a CA65 debug file output, i.e. use --dbgfile on the ca65 command
line. The debug file is then read with the new ENVI.S command of the monitor.
The math pack in the built-in Os ROM had a bug in the BCD to ASCII conversion
which could not print signed zeros and some denormalized numbers correctly.

This got fixed.

The math pack could not handle signed zeros in the BCD to integer conversion,
fixed.

The BCD to integer conversion was pretty slow. The new release replaces the
algorithm completely, making it a lot faster.
