Эмулятор Amstrad CPC для Windows.

Emulation -.Improved palette change emulation. - Z80 MEMPTR emulation. - Correct Z80 Flags emulation. - Fixed Z80 DAA instruction. - Re-mapped AY output volumes (again!). - Changed volume percentage of B channel to 75%. - Doubled the period for noise register. - Digiblaster and AmDrum emulation. - Allow read of AY register 15. - Fixed small residual volume on tape input when read bit was zero. - Fixed full residual volume on tape input when motor is turned off (and last bit read was high), previously caused disable of AY channel A. - Allowed for up to 32 Upper ROMs. - Allowed disc images to use up to 162 tracks (81 cylinders). - Fixed a keyboard bug with certain keyboard drivers returning key 0 as pressed (which was used for the (None) value). This caused multiple keys to be always pressed at the same time in the emulation. - Forced at least one tape read per frame to ensure tape progresses while playing even if the PPI is not read. - Reduced Tape Stall period when Tape Motor is turned off. - Changed CDT/TZX T-State conversion to 3470000 rather than 3500000 to allow some (badly created?) CDTs to work. - Fixed CDT/TZX Direct Recording block support. - Fixed CDT/TZX bit state transition (stays high for 1ms if that was the last state). - Changed CDT/TZX Standard block timing to match specification. - Fixed error on load of empty tape image. - Emulation of Dobbertin SmartWatch (Read Only), not currently available with SNR recording. Configuration -.Split Display configuration for Windowed and Full Screen separate values for various options. - Added Digiblaster option to Printer port configuration. - Added the ability to select (None) for any unmapped key. - Added FIRE 3 to keyboard/joystick configuration. - Forced ROM remapping after configuration changes so the ROMs are changed immediately. Tape Monitor - Added hints for details on various blocks. - Improved display of tape motor status. Debugger - New Memory Read/Write and Input/Output Breakpoints. - Disassembler display now shows in colours similar to assembler. - Added Pass Count to all Breakpoints to allow the number of passes before breaking to be defined. - Added the ability to Load and Save breakpoints from the Breakpoints window. - Fixed Follow PC and Break Instructions checkboxes. - Improved position checking for windows, allowing for multiple displays. - Improved row and column highlight and removal especially in full screen mode. - Breakpoint Window Condition editor resized with window. - Breakpoint Condition form now validates the condition when Ok is clicked. - GoTo no longer requires full 4 digit hex number to be entered. (eg. 38 can be entered rather than 0038). - Added Timers and associated window. These are controlled using breakpoint condition functions timer_start and timer_stop. - Added a number of variables to breakpoint conditions (eg. MODE, palette_select). - Ensured all breakpoints evaluate even on single-step and/or if another breakpoint triggered first. - Improved breakpoint condition function parameter count checks. - Add a hint to the Soft-Scroll register showing X and Y scrolls and blanking value. - Added the ability to load NOI symbol files using the Assembler Symbols window. Assembler - Editor support for Undo and Redo. - Display and move to correct column when TAB characters are used. - Display a * in the tab to indicate when a file has been modified but not saved. - Added a Save All menu item in the File menu. - Added SLL undocumented Z80 instruction. - Fixed OTDR instruction to output ED BB. - Fixed INCBIN access violation with empty include path when file not found. - Added an extra parameter (offset_high) to INCBIN to allow 32 bit offsets within the file. - Added an optional word parameter for RST instructions (eg. RST #18,label). - Added MEMORY function to read emulator memory during assembly. - Added CHECKSUM function and directive to produce a checksum or CRC for a region of memory or assembler output. - Added SAVE directive to save emulator memory to a file or direct to disc image. - Option to conditionally push PC to stack on run. - Option to automatically hide the output window on successful assemble. Snapshots - Added VerticalHold (Offset #99) and MemEnable (Offset #9A). (See CPCWiki Version 3 SNA document for details). AVI Writing - Forced writing of AVI frames on every frame refresh. - Forced emulator to full size if full size AVI is required. User Interface - Stopped F8 key from entering debug mode while currently stepping over an instruction. - Patched VCL to fix ALT key causing controls to disappear. - Improved ALT, ESC and F10 key handling (You can now press CTRL-SHIFT-ESC without launching Windows Task Manager). - Added Normal Speed (100%) (SHIFT-F3) and High Speed (1000%) (SHIFT-F4) options. - Fixed a lot of form and font scaling issues. - Fixed Rename menu in disc editor. - Fixed Overwrite prompts and default extensions on file dialogs. Other - Support for HTML Help in newer versions of Windows. - Added /SHUTDOWN and /SHUTDOWN:FORCE command line parameters to shut down Windows when emulator is closed. - Added /SN:filename command line parameter to load a snapshot or recorded session. - Fixed a bug with SNR time calculation. - Force Vertical Hold to zero for session recording. - Added PCW and VORTEX formats. - Fixed a bug retrieving and writing blocks to/from CP/M format discs (ROMDOS formats with incorrect DPB extent mask entries D80/D40 etc). - Improved detection of double-stepped disc images. - Allow IMG files to be used as IDE drives. - Support for LBA-48 read and write commands (#24, #34) supporting up to 2TB (32-bit sector address). - Improved IDE status handling and handling of IDNF errors. - IDE CHS translation. - Some support for Get Drive Parameters command (#EC). Known Issues - The ASIC does not allow a number of registers to be read. This does not affect any current CPC software, and needs to be analysed fully before being emulated.
