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 Previous changes (pre 1.2.0) are in the CHANGES file.
