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
