Version ?.?.? (????/??/??)
This release contains changes in color handling. Users updating from
an earlier version should reset their color settings, or else the display
might be unreadable. To reset the color settings, do one of these:
* Select one of the presets available in the menu option "Display settings"->
"Color preset"; or
* Run atari800 with the -color-preset command-line option, e.g.:
atari800 -colors-preset standard; or
* Delete the emulator's config file (.atari800.cfg). Caution: you'll lose
all Atari800 settings!
New features:
-------------
* Support for loading of CAS images with "fsk" chunks - images of
copy-protected tapes can now be loaded, with SIO patch being disabled.
* Bit3 Full View 80 Column card emulation.
Changes:
--------
* The Sound Settings option "Fragment size" has been renamed to less cryptic
"Hardware buffer size".
Fixes:
------
* Fixed computation of gamma adjustment - now it is applied to each of the
three RGB channels separately.
* On systems that support synchronized sound: Fixed the emulator crashing
when Dual POKEY was enabled while High Fidelity POKEY was turned off.
* Improve screen update routines in the Dreamcast port. They don't use
DIRTYRECT anymore but are faster than the old routines when the whole
screen is dirty.
Version 3.1.0 (2014/04/12) - release cooked at Atariada.cz
Highlight of this release: Raspberry Pi port by Andrey Dj
Hidden easter egg: on-screen keyboard in SDL by Christian Groessler
All the following work has been done by Tomasz Krasuski:
General new features:
---------------------
* More accurate emulation of PAL colours (based on analysis of oscillograms
of real PAL GTIA output)
* Improved PAL blending, working on all grayscale pixels and is accurate now
(can be enabled/disabled in "TV effect" display settings)
* common sound layer implemented (SDL, JavaNVM, OSS, DOS) with synchro sound.
* synchronized sound is now supported by both POKEY sound engines.
* turbo mode (F12) is considerably faster
* Added cartridge mapping used by "Turbo Hit"/"Atari Blizzard Hit".
* Added MegaMax 2 MB cartridge mapping.
* Added read-only support for the 4 MB Flash MegaCart mapping.
* Added minimal support for The!Cart.
General Fixes:
--------------
* fixed possible unnecessary cartridge bank switching
* fixes and clean up in Java port
* fixed diagnostic cartridge cold start (doesn't send Start+Option)
* fixed two old bugs in DOS sound (pitch being wrong and sound missing)
* fixed keyboard not working for ncurses video and OSS sound
Version 3.0.0 (2013/03/03)
New features:
-------------
* Option to automatically save configuration on exit
* More settings saved in configuration:
- currently attached tape file
- cartridge settings, including currently attached cartridges
- state of R-Time 8
- system settings, including Mosaic/Axlon RAM size
* New Tape Management menu - can now create blank tape images, switch tape
to read/write in order to save additional data at the end of the current
tape image, rewind/fast forward the tape, and mark it as read-only. See
DOC/USAGE for details.
* Displaying tape position when "Show sector/block counter" is enabled.
* Reworked Cartridge Management menu - now displays filename of the
attached cartridge.
* Option to disable restarting of the machine after cartridge change.
* When attaching a cartridge from the command line, cartridge type can now
be specified using the new -cart-type and -cart2-type options.
* New cartridge types supported:
- OSS 8 KB cartridge
- OSS two chip 16 KB cartridge (043M)
- Blizzard 4 KB cartridge
- AST 32 KB cartridge
- Atrax SDX 64 KB cartridge
- Atrax SDX 128 KB cartridge

- Turbosoft 128 KB cartridge
- Ultracart 32 KB cartridge
- Low bank 8 KB cartridge
- SIC! 128 KB cartridge
- SIC! 256 KB cartridge
- SIC! 512 KB cartridge
- Standard 2 KB cartridge
- Standard 4 KB cartridge
- Right slot 4 KB cartridge
* The configure script can now auto-detect some of the available display and
sound interfaces before compiling.
* Option to enable XEP80 added to The Emulator Settings menu.
* Emulation of the 1200XL, including console LEDs, no built-in BASIC, the
F1-F4 keys (mapped to arrow keys in the SDL version) and the on-board
J1 jumper.
* Emulation of the XE Game System, including the built-in game and
detachable keyboard.
* Revamped the Select System menu (now called System Settings). Can now
select many system settings, including RAM expansions, OS and BASIC
revision, and more.
* System ROM settings moved to a separate menu. Now it stores paths to all
known official revisions of the Atari OS, the 5200 BIOS, all BASIC
revisions, and the XEGS built-in game. The OS revision to use is chosen
automatically when selecting a machine type (for example, the 400/800 OS
PAL or NTSC version is chosen depending on the selected TV system).
* 400/800: Emulation of all RAM sizes achievable with different combinations
of the CX852 and CX853 modules - from 8 to 48 KB.
* Emulation of 32/48KB memory sizes in the XL/XE mode, compatible
with memory expansions for the 600XL manufactured by RC Systems.
* Emulation of the MapRAM hardware hack.
* Display settings: "Hue" renamed to "Tint". Tint now configurable also in
PAL mode.
New Android port features:
--------------------------
* Renamed Atari800 Android port to "Colleen"
* Implemented extended key remapping
* Implemented the B: device (8-bit games can reach the web now)
* Support for Xperia play keycodes added
* Remapped dpad enter to break
* Added paddle emulation
* Optimized file selector, allow roaming outside of ext. storage dir
* Added an exclusion border for paddle mode
* Implemented state saving
* Implemented Planetary Defense mode, a Koala Pad click-where-I-point mode
* Natively supported UI on post-Honeycomb devices
* Fixes for Jelly Bean (audio stuttering, keypad dialogs, soft keyboard)
* Added new dialog for cartridge type selection
* UI fine tuning
General Fixes:
--------------
* Bugfixes in cassette emulation - works reliably even for tape images with
long (> 4096 B) blocks.
* Fixes in save states - loading of save states works correctly even with an
attached bank-switched cartridge or with an Axlon/Mosaic RAM expansion.
Note 1: Format of the state files has changed. Old save states can still
be opened, but newly-created ones cannot be opened in older versions of
Atari800.
Note 2: Tape position is not restored on loading of save states. Do not
save state during tape loading/saving - it won't work as expected.
* "Disable BASIC when booting Atari" no longer emulates pressing of the
Option key when in the 400/800 mode.
* Fixed a bug with BASIC sometimes disabling itself when switching system
type to 400/800
* Minor bugfixes in file selector
* Fixed emulation of SpartaDOS X piggyback cartridge functionality
* "Save Screenshot" fixed - it saved an interlaced screenshot instead of a
normal one.
* SDL version: Swapped mapping of right and middle mouse buttons, to make it
identical to the X11 and Win32 ports.
* Monitor: fixed displaying/disassembling of memory area $D000-$D7FF - with
the new supported cartridge types, code may reside on page $D5, and now it
can be debugged.
* SDL version: fixed a blue border when in OpenGL BGRA32 mode.
* Minor fixes in parsing of command-line options.
* Rewritten XEP80 emulation - now more accurate and supports switching
between NTSC/PAL modes with correct aspect ratio. XEP80 emulation now
requires a charset ROM image, path to which should be set in the
XEP80_CHARSET line in the config file.
* Fixed operating system patches not working with all official revisions of
the OS.
* Fixed emulation of separate ANTIC/CPU access to XE RAM when Self-Test is
enabled.
* Fixed the emulator menu sometimes being displayed incorrectly (missing
font) when running without an OS ROM image.
* Improved accuracy of generated colours in PAL mode.
* Fixed emulation of the H: read operation - Turbo Basic's BLOAD now works
on H: devices.
Version 2.2.1 (2011/04/28)
Quick update fixing some annoying bugs from the previous release
and adding some new host screen optimizations and improvements:
* X11 target can be compiled again
* SDL sound on *BSD should work
* older compilers (DOS/BeOS) should compile again
* many SDL/OpenGL workarounds for Microsoft Windows libSDL bugs
* IDE fix and CF emulation
* some small Android fixes and new arrow key derotation workaround
* UI sliders used for more settings (video area/shift options)
* several command line options renamed to be more intuitive (see the USAGE)
* automatic detection of host screen aspect ratio
* added option for disabling OpenGL Pixel Buffer Objects
* added option for enabling video synchronization with vertical retrace
* added option for selecting pixel format in OpenGL
* now saves the Show Speed/Disk Activity/Sector Counter in the settings
Version 2.2.0 (2011/04/02)
Another update after two long years. A lot of changes and major improvements:
New features:
-------------
* SDL features synchronized sound (GTIA+POKEY digisounds play properly now)
* SDL display enhancements (hardware accelerated using OpenGL)
* DirectX display enhancements (also hardware accelerated)
* Improved NTSC and PAL colours (presets: Standard/Deep Black/Vibrant)
* Austin Franklin 80 Column card
* Emulate the Alien Group Voice Box I and II
* Added support for F12 turbo mode.
* IDE emulation (compatible with MyIDE)
* New Android port by Kostas Nakos (available in the App Market already)
* Auto frame skip for slower devices (currently enabled for Android only)
Fixes:
------
* trak-ball (cx22) emulation fixed
* SDL: leftmost column missing in 16/32bpp fixed
* DirectX default for Win32 SDL
SDL Display enhancements:
-------------------------
1. Fullscreen resolution - this gives a list of all available resolutions from
which a user chooses one. The default resolution is the next-bigger-than
336x240.
2. Fullscreen: yes/no - obvious. Window size is independent from the chosen
fullscreen resolution and can be changed by resizing the window.
3. Rotate sideways: yes/no - rotates the screen by 90 deg. Works as earlier,
ie. only for "standard" display (no NTSC filter, no 80 column card).
4. Stretch - this option controls how display stretching (scaling) is
performed. We can select one of:
a) none - no stretching at all
b) integer multiples (default) - width and height will be resized by 1x, 2x,
3x etc.
c) full - stretching is unrestricted, display will cover the entire screen.
5. Keep aspect ratio - this option controls how the display's aspect ratio is
corrected. 3 options available:
a) disabled - no aspect ratio correction, display will fill entire
screen/window,
b) 1:1 (default) - width and height will be multipled by the same value
c) like real TV - display will be resized to reflect pixel aspect ratio of a
real Atari connected to a TV. Atari pixels are not square; pixel width-to-
height ratio is about 0.857 for NTSC and 1.039 for PAL. This option reflects
that.
6. Host display aspect ratio - here the user enters aspect ratio of his
monitor. This value is used to properly compute display aspect ratio when
"Keep aspect ratio" is set to "like real TV". Set it to 4:3 (default), 16:9,
1.78:1 etc.
7. Horizontal view area - this option sets the size of Atari screen area
visible horizontally. Choose one of:
a) narrow - 320 columns wide,
b) normal (default) - 336 columns wide,
c) full - 384 columns
d) custom - lets the user enter any value between 160 and 384.
8. Vertical view area - similar to above:
a) short - 200 lines high
b) normal (default) - this setting is TV-system-dependent. In PAL this makes
all 240 lines visible, while in NTSC top and bottom 8 lines are hidden, which
leaves 224 lines visible. I've made this as such because apparently on NTSC
TVs not all 240 lines are visible. The value of 224 was taken by taking full
NTSC height (480, divided by 2) and cutting top and bottom 3.5% (different
sources say 3.5% is the "action-safe" overscan area).
c) full - 240 lines high
d) custom - any value between 100 and 240.
9. Horizontal offset - when amount of columns displayed is less than 384, this
option "shifts" the visible screen area. Setting to higher than 0 shows more
of the right side, and lower than 0 shows more of the left side.
10. Vertical offset - similar to above.
Additionally, the Alt+Shift+X shortcut that switches beetween standard<->80
column display is now also available as "Display settings->80 column display
if available: yes/no".
The Alt+B switch however has been removed - since setting black/white colours
can be done in Display settings anyway.
All new options are also available from command line and are saveable in
configuration.
New Android port features:
-------------------------

Thanks to Perry McFarlane and other developers for their contributions
to this release. Enjoy Atari800!
Version 2.0.3 (2007/07/11)
This is probably the last release that is based on the source code
written by David Firth back in previous century.
A completely new Atari800, written from scratch, with even better
portability and maintainability is being planned so stay tuned!
Changes:
--------
* new style of artifacting

Version 2.0.2 (2006/04/08)
There is a new NTSC emulator available thanks to Blargg (Shay Green)
(http://www.slack.net/~ant) and NewRisingSun who made the original algorithm.
You can access it with -ntscemu in the SDL port only.
Only 640x480x16 is supported and will be invoked automatically.
You will need a fast processor (~700 MHz or so).
This code should be considered experimental but I hope you
will try it and report any problems. Please experiment with the
many settings and compare them with a real NTSC Atari if you have one.
If you come up with better settings than the current defaults please provide
feedback. Try -ntsc_burst 0.70 in Drol, Choplifter and Ultima.
Please read DOC/USAGE and check -help.
Changes:
--------
* Blargg's NTSC composite video emulator, based on NewRisingSun's Algorithm.
* small fixes in ANTIC/GTIA emulation
* fixed DCM image handling (broken in 2.0.0)
* added emulation of Atari XL/XE with 192 KB RAM
* integrated SEGA Dreamcast port
* Atari Inverse key mapped also to "`" (backquote) in SDL port (MS Win users)
* some minor improvements
* much more DOC/TODO
Version 2.0.1 (2006/01/02)
Just a quick UI bugfixes release.
Version 2.0.0 (2005/12/31) - celebrating decade of Atari800 development!
This release brings major source code clean up, numerous bug fixes and
many great new features and important improvements. 98% of changes since
last release have been made by Piotr Fusik - admire his dedication
to Atari800 project while you will be browsing through the impressive list
of changes below.
Run-time configuration (via the .atari800.cfg file) has been improved.
All configuration options are now available in the User Interface.
Remember to use "Save configuration file" when necessary.
If you are new to Atari800, press F1 and select "Emulator Configuration"
to configure the ROM images. This can be easily done with
"Find ROM images in a directory".
DISK_DIR, ROM_DIR, EXE_DIR and STATE_DIR configuration options are no longer
supported in this version. You need to re-select your directories
using "Emulator Configuration" -> "Configure directories".
Changes:
--------
* auto-starting any file supported by the emulator
via the command line, User Interface or Alt+R

file was found; now a default configuration is written and you can
modify it using User Interface; the easiest way to configure ROMs is
"Find ROM images in a directory" which looks for common names of ROM images
* DISK_DIR, ROM_DIR, EXE_DIR and STATE_DIR configuration options replaced
with ATARI_FILES_DIR and SAVED_FILES_DIR
* sound recording now works (was completely broken)
* new in User Interface: "Emulator Configuration", "Controller
Configuration", "Save Interlaced Screenshot", "Uncompress Disk Image"

config file parameters that expect values from SDL keySyms.
Version 1.3.2 (2003/12/20)
Highlights since previous release:
----------------------------------
* R: can now be hooked to a real serial port (no runtime config yet)
* various ANTIC and POKEY fixes for perfect software compatibility
* disk and cartridge info saved in the state files
* casette handling greatly improved
* even more cartridges supported (40 now!)
* some rare buffer overflows fixed
Version 1.3.1 (2003/09/04)
Highlights since last 1.3.0 release:
------------------------------------
* rewritten and much improved configure script
* new cartridge types supported (38 types now!) - see DOC/cart.txt
* Disk Sets - loading and saving of D1-D8 set is possible in the UI
* R: as the Atari850 serial port emulation added - see DOC/r_device.txt
* updated and improved m68k assembler emulation of the CPU
* XF551 HighSpeed transfer emulation added
Version 1.3.0 (2003/02/10)
Highlights since last 1.2.5 release:
------------------------------------
* new HiFi sound (you may en/disable it in the UI)
* new cycle-exact Antic emulation
* "H:" emulation complete (including subfolders)
* Paged memory implementation (fast XE bank-switching)
* new configuration file name and location ($HOME/.atari800.cfg)
Detailed list of changes follows:
* configuration file ("atari800.cfg") related changes:
1) configuration file is renamed to ".atari800.cfg" by default (note
the leading dot in the name, similarly to most other configuration
files of programs on Unix platforms). On DOS/TOS (FS 8+3 limitation)
the old "atari800.cfg" will be supported.
2) RT-Config (the module in Atari800) tries to search the configuration
file in user's home folder first (environment variable HOME should
point there). If it's found then it's used. If it's not there then
RT-Config tries to open system wide configuration file (by default
it's "/etc/atari800.cfg"). Please note that the system wide file is
not updated by Save function of RT-Config because it's expected
that this file is read-only for regular user.
3) RT-Config can also be told where your configuration file is by
using the "-config <filepath>" command line parameter. If the file
is not there yet it's created. So it's quite easy to let Atari800
create a test config file and compare it with your current config
or to have several config files for various game/demo/application
uses of the Atari800 emulator.
4) Some config file options were renamed or otherwise changed some
time ago already but they were still recognized. This is no longer
true so better create a new config file from scratch.
5) There are two new important switches - "ENABLE_NEW_POKEY" and
"STEREO_POKEY" so better create new config file so you get these
options configured properly.
* new Sound:
The new MZ POKEY emulation is now enabled by default on all ports.
Also the STEREO sound (Dual POKEY) is compiled in by default
but is not enabled (so there's a single POKEY by default but you
can enable the second one very easily in the User Interface (press F1).
Both can be en/disabled in the configuration file (call atari800 with
the "-configure" parameter to reconfigure these and other options).
Win32 and SDL ports also recognize a new cmdline switch "-audio16"
that switches to 16-bit sound.
Unreleased version 1.2.10 (2003/02/09)
* autoconf 2.5x required for building the source fetched from CVS.
However, released source code comes with prebuilt configure script
so you shouldn't even notice this change.
* SDL version contains the same keyboard IRQ fix that was recently
done in the general input core. In human language: Super Pacman 5200
will not crash after SHIFT and * keypress.
* On-the-fly change of POKEY emulation core (old Ron Fries' or new
Michael Borisov's). Compare the new HiFi sound with the previous one.
Unreleased version 1.2.9 (2003/01/27)
* New cycle-exact ANTIC/GTIA emulation. Enabled by default, disable by
./configure --disable-cycleexact
Unreleased version 1.2.8 (2003/01/27)
* Paged memory implementation finished. Disabled by default, enable by
./configure --enable-paged
Unreleased version 1.2.7 (2003/01/27)
* Harddisk emulation now complete including support for subdirectories.
Unreleased version 1.2.6 (2003/01/27)
* New sound core and 16 bit sound support -- high sound quality but slower.
Use -audio16 option to enable 16 bit sound and -quality <level> to set sound
quality (level > 0 enables new sound core) on the win32 port.
Consult port specific doc for command line details.
Version 1.2.5 (2002/12/02)
* UI - the SpaceBar in disk management switches between the RW and RO flags
(this didn't work for a long time, now fixed). Please note that this RW/RO
switch is just temporary and does not change the writeprotect flag of ATR
images. Besides, it cannot override this flag so you actually can't mount
a writeprotected ATR image read/write using this Space Bar toggle.
* Atari800 compilable under OS/2
* MultiJoy4 interface and Amiga/AtariST right mouse button supported
* 13 new cartridge types supported
* ANTIC mode E + GTIA mode 9 added (used in "Unconventional 2k", "Ass Kisiel")
Version 1.2.4 (2002/08/07)
* 576 and 1088 kB RAM supported (selection available in the UI)
* separate Antic access to extended memory for 130 XE and 320 Compy Shop
* 256K and 512K XEGS carts
* SDL version now
- cleans up after unsuccessful initialization
- supports "-nosound" and "-dsprate"
- continues to run even if sound initialization failed
* command line options "-help" and "-v" ("-version") now work better
in most supported ports.
Version 1.2.3 (2002/07/08)
* 16 kB RAM machines (Atari 400/600XL) emulated
* LPTjoy support added to the SDL port
* SDL port is generally much improved. To get list of SDL specific options
start the SDL version of Atari800 with -help.
* casette image loading accessible from UI
* -palette option (for loading an alternate ACT color palette file) fixed.
* channel 1 in stereo mode fixed
* antic: NMIST bit 5 fixed (is always zero)
* input: second button in 5200 joystick generates "Break key" IRQ
(you can now jump in "Moon Patrol" - use Shift)
* monitor: "DLIST" now accepts address as an argument
* antic: Dirty update scheme that allows slower machines to run Atari800
at full speed now! See DOC/HOWTO-DIRTYRECT for more information.
* pokey: allow high-speed disk i/o (Alpha-Load works, thanks to Paul Irvine)
Version 1.2.2 (2001/12/31)
* Falcon .s files had to be renamed to .asm, otherwise the vga
port could not be built.
Version 1.2.1 (2001/12/31)
* serious memory overflow bug fixed (caused crashing of X11 port
and probably also other unexpected bugs or problems)
* joysticks in SDL port fixed and improved.
* RPM's .spec file fixed.
Version 1.2.1pre0 (2001/12/17)
* Falcon port configurable and buildable again
* SDL support for 32-bit display, screen width switching (LALT+g)
* documentation updated (still can be much improved :)
* util/ folder contains new sethdr and act2html utilities
* configure process is non-interactive (doesn't ask any questions)
* RPM .spec file for easy building of Atari800 from source .tar.gz
Version 1.2.0 (2001/11/29)
* completely new SDL port (use ./configure --target=sdl) that should run
on most/all platforms/OSes SDL supports (http://www.libsdl.org/)
* completely new WinCE port
*** New features:
* support for Express, Diamond, SpartaDOS X, XEGS, Action!, BASIC XL
and other cartridge types (see cart.txt for complete list).
The "-cart" option runs CART files and all types of raw images.
"-rtime 0" disables emulation of R-Time 8.
Thanks to:
- Jindroush, who described most of the cartridge types
- Nir Dary, for information on 8*8 KB D50x and OSS 'M091' cartridges
* mouse can emulate following devices
(in parentheses the option that enables emulation):
- paddles (-mouse pad)
- Atari Touch Tablet (-mouse touch)
- Koala Pad (-mouse koala)
- Light Pen (-mouse pen)
- Light Gun (-mouse gun)
- Amiga mouse (-mouse amiga)
- Atari ST mouse (-mouse st)
- Atari Trak-Ball (-mouse trak)
- joystick (-mouse joy)
For Atari 5200 you can use "-mouse pad" (good for Gorf and Kaboom)
or "-mouse joy" (good for Missile Command and Super Breakout).
Use "-mouseport <1-4>" to select the Atari port.
Use "-mousespeed <1-9>" to select speed (default is 3).
* cassette recorder emulation! (experimental)
Currently only reading works and only with SIO patch.
Supported are:
- CAS files - the digital cassette image format by Ernest Schreurs.
The format handles different lengths of blocks, gaps, non-standard blocks,
baud rates and more. See http://home.planet.nl/~ernest/home.html
for the excellent WAV2CAS converter, which includes detailed description
of the format. Atari800 supports the format only partially at the moment.
- raw files - any file can be attached, as if it has been written
to the C: device (standard Atari OS format).
No UI available yet. Attach a file with "-tape filename"
or "-boottape filename" (emulator presses Start and Space to boot the tape).
* SIO, H: and P: patches are now independent and can be toggled at run-time
* the H: device no longer replaces C:.
The H: device is now added to HATABS in RAM, and the escape codes
are put in 0xd100-0xd1ff, so H: doesn't modify Atari OS at all.
* "-basic" and "-nobasic" work for Atari 800 (Atari BASIC is attached
as a cartridge in Atari 800)
* devices: added open mode 9 (append) for H: device
* input: the illegal joystick positions (e.g. left+right) are not passed
to the emulated Atari (good for "Mario Bros.")
* monitor:
- "C 600 ABCD" does the same as "C 600 CD AB"
- 1 KB boundary is respected by "DLIST"
- "POKEY" command
- "S" without parameters repeats last search
* ui: added Atari Settings (enable/disable BASIC, R-Time 8, SIO patch, H:, P:)
*** Compatibility improvements:
* antic,gtia: the background color can be changed inside a scanline.
Currently implemented only for blank lines without PMG.
Try the "Partyland" part of the "Bitter Reality" demo.
* antic: corrected timing of DLISTL/H ("Spelunker" works)
* binload: 0x31 stored at 0x300 ("Studio Dream" loads now)
* cpu: Read-Modify-Write (RMW) instructions (ASL, INC, etc.) store
the unmodified value of $D01A before they store the modified value.
Now you can see the white dots made with INC $D01A.
* cpu: on reset, the I flag is set (now reset works if stuck in interrupts)
* devices: replaced "dGetByte(0x2e)" with "regX" in H: handler routines
(fixes problems with Atari BASIC's GET/PUT/INPUT/PRINT)
* pia: & 0x3f on read PACTL and PBCTL
* pokey: potentiometers emulation improved: POTGO and ALLPOT registers
and bit 2 of SKCTLS implemented, "Tree Surgeon" no longer hangs
* pokey: true RANDOM emulation (both 9- and 17-bit poly) !
Not using rand() anymore. Try the "Bank Bang!" game.
* pokey: fixed STIMER (speech in "Mirax Force" is better, but still
not perfect)
* pokey: a few fixes for stereo detection routines (helps "Sheol",
"Total Daze", "Crockett's Theme"...)
* pokey: fixed SERIN ("Timeless Announcement" loads now)
* pokeysnd: added exact poly9_lookup and poly17_lookup, removed bit17
(which was initialised with rand()) saving ca. 100 KB of memory.
Do you hear any difference?
* sio: made double density ATR images compatible with SIO2PC
*** Bug fixes:
* cpu: fixed wrong extern
* devices: fixed Device_isvalid (problems with trailing 0x9b)
* rtime: added "byte &= 0x0f" to prevent out of bounds accesses
to regset[]
* sio: corrected and added checks if drive number is in range 1-8
* sio: Format Disk rewritten. Now it can resize both ATR and XFD images.
The ATR header is being updated. Double density format works.
*** Optimizations:
* antic: optimized ANTIC_Load and character modes
* atari_vga: no unnecessary Atari_DisplayScreen() calls if "-refresh" is used
* cpu: slight optimization of ROL and ROR
* gtia: optimized players in new_pm_scanline
*** Clean-ups in sources (for programmers):
* created cartridge.[ch] and rtime.[ch], removed supercart.[ch]
* created input.[ch] to handle keyboard, joysticks and mouse
* removed enable_rom_patches, added enable_h_patch and enable_p_patch.
Original OS is saved in atari_os. Removed SetSIOEsc() and RestoreSIO().
After changing enable_*_patch call Atari800_UpdatePatches().
* replaced following variables: machine, mach_xlxe, Ram256, os,
default_system and enable_c000_ram with only two: machine_type and ram_size
(ram_size is in kilobytes, and there're #define's for 320 Rambo/Compy).
There are no more Initialise_Atari... routines. Instead, set machine_type
and ram_size and call Atari800_InitialiseMachine().
* moved main() to platform-dependent code,
created Atari800_Initialise and Atari800_Frame
* removed i386 asm tricks
* diskled: rewritten to be cleaner and more flexible
* pokey: SKSTAT variable renamed to SKCTLS to avoid confusions
(it's the write-only, not the read-only Pokey register)
* pokeysnd: removed duplicates of Pokey constant definitions
and AUDC/AUDF/AUDCTL variables, included pokey.h
