CPCEC / ZXSEC (2019/10/04) is released. CPCEC is an emulator of the family of home microcomputers Amstrad CPC (models 464, 664 and 6128) whose goal is to be loyal to the original hardware and efficient in standard modern systems. Thus it brings a faithful emulation of the Z80 microprocessor and it replicates the behavior of the CRTC 6845 and Gate Array video chips, the PSG AY-3-8912 sound chip, the remaining circuits found in the original hardware, and the tape deck and floppy disc drive that made possible loading and running software. ZXSEC is an emulator of the Sinclair Spectrum family (48k, 128k, +2/Plus2 and +3/Plus3) based on the components it shared with the Amstrad CPC family: the Z80 microprocessor, the PSG AY-3-8192 sound chip, the tape system and the NEC765 disc drive controller.
CPCEC / ZXSEC (2019/10/04) changelog:
20191003 -- twelfth public release. Precise (albeit not perfect yet) memory contention and ULA noise ("snow") on Spectrum: "48K Timing Tests" passes all tests but 36 and 37, and "128K Timing Tests" fails on just six tests. "Mask 3: Venom Strikes Back" draws the attribute and border effects on their precise locations on all platforms (48K, 128K/Plus2, Plus3) and Software Creations' "Black Lamp", "LED Storm" and "Sly Spy" behave well on 128K machines. Improvements in the debugger: fixed disassembly panel invalid cursor locations, added optional tall characters, avoided debug+pause clashing, new key M toggles memory dump ROM+RAM and RAM-only modes. Improved ZIP handling (ZIP archives are no longer locked, files within archives are filtered by extension), user interface fixes.
20191004 -- minor patch making the debugger options set with V and M stick between sessions.
