Eine neue Version des Amstrad CPC Emulators CPCEC ist erschienen.

A new version of the Amstrad CPC emulator CPCEC has been released.

  • 20220412 -- twenty-third public release. CSFEC is a new Commodore 64 emulator: it passes several tests from the PC64 suite (CPUTIMING, CPUPORT and the entire MOS 6510 opcode set) but fails others (IRQ, NMI and all CIA tests); it supports up to two extra SID chips (either $D420 and $D440 or $DE00 and $DF00) but the VIC-II emulation is incomplete (no badline handling, no sprite contention); it can load PRG files and play T64 and TAP tape images, but it doesn't emulate the C1541 disc drive yet and thus cannot handle D64 disc images at all. New virtual joystick interface: the user can redefine the keys that simulate the virtual joystick instead of sticking to the keys Z and X and the cursors. Tape analysis can detect musical loaders: tape acceleration will be temporarily disabled to ensure that songs play normally. Fixed a bug in the Z80 (the internal timings of OUT (n),A were wrong) and the LA-7800's horizontal synchronisation (both reported by Hicks): the CPC demo "Onescreen Colonies #2" behaves properly.
  • 20220307 -- minor patch fixing a bug in the "half scanlines" mode and several omissions in the debuggers.
  • 20220303 -- twenty-second public release. Major internal changes in the debugger: most of it is now part of the general library, only the Z80-specific features stay in the Z80 module. Toggling the debugger's illegal opcode behavior is now done with the key "," (comma); its old key "Q" now runs until the next interruption. The debugger styles (keys "V" and "Shift+V") now include a translucent mode where the emulated screen is visible through the debugger text. Minor optimisations in the video renderer (merge vertical position and frameskip tests), the AY chip (fewer calculations) and the Z80 emulation (reduced banking in operations that read and write the same address). Small tweaks in CPCEC ("Octopus Pocus" for CRTC0 works well at last), ZXSEC (SZX snapshots are now the default choice, SNA format is now secondary), the FDC ("READ ID" must fail when using the wrong density: noticed by Roudoudou), the audio extensions (now Playcity and Digiblaster can be enabled at once, as well as Turbosound and Covox $FB) and the video filters (weakening image contrast rather than saturation).
