Changes in 0.2.1 ---------------- - Created a new Makefile for Unix. The Amiga support is now in Makefile.amiga - Sorry, but I renamed the ATARI800 environment variable to ATARI_LIBRARY which points to /usr/local/lib/atari by default. - Control + Shift + Key combination for Linux SVGALIB implementation. - SVGALIB version can be restarted after entering the monitor. - HELP Key available in XL/XE mode - Optional XVIEW (V3) Interface for X Window version. Allows disk changes using a file selector, controller configuration and access to performance variables. - BREAK Key fixed - PC Joysticks can be used with Linux (svgalib, x11 and xview) through the /dev/js0 and /dev/js1 devices. Second button activates the space bar which is very useful in Defender :-) Build with "make " where is one of:- linux-x11-joystick, linux-xview-joystick or linux-svgalib-joystick - X11 Joystick emulation using keyboard re-implemented. Straight X11 can use either numeric keypad or cursor keys + space. XVIEW can only use cursor keys + space (Problem using keypad in xview!) - Disk selector for Amiga version + controller configuration menu - Started code to emulate SERIN and SEROUT registers. At the moment this is ongoing and does not work. New startup option -nopatch disables the SIO patch leaving the normal SIO routine in place. Changes in 0.2.0 ---------------- - Separated Playfield Scanlines from Player Missile Scanlines - Corrected playfield colour errors in Antic modes 8 & 10 - Horizontal Fine Scrolling - Playfield and Player/Missile Priorities - Allow Emulator to run either as an Amiga Screen or Window - Added Paddle support for Amiga Changes in 0.1.9 ---------------- - Corrected bug in IRQST and IRQEN - Corrected minor bug in player missile collision detection - Amiga version is now full screen + Menus - Faster disk I/O - Added ATARI800 environment variable. This allows the emulator to be run from different directories. If ATARI800 is unset it will still try to load the OS images from object/ below the current working directory. - colours.h replaces colours.dat - Added man page. - New way of handling Joysticks, Triggers, Paddles and Console Keys - Corrected handling of CHBASE which was causing K-RAZY ANTIKS to display garbage. - Corrected handling of VCOUNT which was causing screen handling errors in Star Raiders (galactic map) and Henri (game screen). - Added Sound API. A test sound implementation is available for the Linux SVGALIB version via /dev/sequencer - It's not very good and has only been used to test the API. It is enabled by starting the program with the -sound option. Listen to the title screens of Necromancer, K-Razy Antiks and Henri (these are the best I've heard). - argc and argv are passed to the platform specific initialisation code - Atari_Initialise(). This allows platform specific options like -sound on the Linux SVGALIB version. - Extra Amiga options -ocs -ecs and -aga. Currently the default is AGA. The -ocs and -ecs have been tested on an A1200 with the OCS and ECS emulation modes enabled. At the moment it is not guaranteed to work on real OCS or ECS equiped machines since it has only been tested under Workbench 3.0. Hopefully someone will provide some feedback. - Another two Amiga options -grey and -colour. The -grey option produces a grey scale display on OCS, ECS and AGA machines. The -colour option produces a full colour display on AGA machines and up to 32 simultaneous colours on OCS and ECS machines. - The DOUBLE_SIZE compilation flag for the X11 version has been replaced by a runtime options. The runtime options are -small, -large and -huge. Changes in 0.1.8 ---------------- - Allows direct use of GRAFP0, GRAFP1, GRAFP2, GRAFP3 and GRAFM without using DMA. - -rom16 option to load standard 16K ROMs. - -a option to load object/atariosa.rom - -b [default] option to load object/atariosb.rom - Simplified screen generation for host - Player missile graphics collision detection has been moved into 'atari_custom.c' - Corrected read from PORTB (XL/XE emulation) - GTIA support for *all* antic modes. i.e. GTIA can be enabled in graphics mode 0 (antic mode 2) just like a real 800. POKE 623 with 64, 128 or 192 to test. - Amiga version can be compiled using either DICE C or GNU C - see Makefile Changes in 0.1.7 ---------------- - Issue cpu cycles during screen update (corrects VCOUNT problem) As a result DLI are not occuring on the correct mode line. - Support for 256 bytes/sector ATR files - Handle Insert, Delete and Tab keys properly - Handle Shift + Control + A-Z properly (X11 only) - Cartridge support tidied up (Thanks to Dave Bennett) Changes in 0.1.6 ---------------- - Correct Colours (Thanks to Chris Lam) - Fetch correct number of screen bytes with horizontal scrolling enabled - Speed improvements for Antic Display Modes - Support for ATR files (128 bytes sectors only) - Support for XL/XE ROM (Reset etc. do not work???) - Corrected Bug in BCD SBC instruction. - Added X11 window Expose event (Thanks to Ivo van Poorten) - Control characters within CURSES (Thanks to Ivo van Poorten) - Improved Portability - Remove '-b' flag (Use -rom object/ataribas.rom instead) - Graphical Support for Amiga 1200 - Faster 6502 Emulation - X11 Joystick emulation now uses the mouse Changes in 0.1.5 ---------------- - CURSES text only mode (Support for various terminals) - Display list jump instruction corrected. - Fixed SIO module (It didn't update DSTATS) Changes in 0.1.4 ---------------- - Changed GetByte and PutByte to macros - Added SVGALIB support for Linux which is much quicker than X11. - Added support for OSS Super Cartridges (Thanks to Dave Bennett) - -rom option to specify alternative cartridges - -oss option to specify alternative OSS Super Cartridges Changes in 0.1.3 ---------------- - Compilation option for double size screen - Trigger now initialises to not pressed - Joystick now initialises to central - Fifth Player support added - Support for Paddle 0 - Preparation for changing GetByte and PutByte to macros. Changes in 0.1.2 ---------------- - Now include in atari_custom.h - Resets count to countdown as soon as it reaches zero. This was causing problems with the RESET Key - count went negative. - Removed XImage structure. I am now updating only the pixels that have changed within a Pixmap. XCopyArea is used to move the Pixmap onto the Window. XCopyArea is not called if no pixels are changed. As a result I am trying a higher refresh rate. - Correction for BASIC version - I left some X11 stuff in resulting in unresolved sybols. - Remove unused status variable from atari_h_device.c - Added some test Amiga Intuition Code - not usable (No Colour or Keyboard) It manages to get the 'READY' prompt up! Atari Basic Blue is one colour and everything else is the other. When keyboard support is added you will be able to use Atari Basic. - Registers are now allocated variables within atari_custom.c. They are nolonger stored in main memory area. Changes in 0.1.1 ---------------- - Outputs an error message when ROM images are not available. Version 0.1.0 ------------- - Initial Release
