Changelog

  • 20191231 -- minor patch fixing a bug in the FDC (bit 6 of SENSE DRIVE STATUS must react when the user changes discs: "Fugitif") and a regression in CRTC0 (detect REG6<REG4 rather than REG6<=REG4: "5KB Megademo 3: Nayad"). Happy new year 2020!

CPCEM 2021/10/04

  • 20211004 -- minor patch fixing a bug in ZXSEC, the Z80 snapshot loader wasn't checking properly the integrity of 48K compressed blocks.
  • 20210930 -- minor patch fixing several bugs in the Z80 (ZXSEC now passes new Spectrum tests such as 48KNEC, EIHALT, IRCONT, BBG48 and BBG128, thanks to Azesmbog, Dunny, Woody and ZJoyKiLer), a glitch in the CRTC (the HSYNC filter required by "Onescreen Colonies" and "Scroll Factory" was harming "Paradise Megademo part 2" and others) and another one in the AY chip ("Stormbringer" for CPC needs more leeway than "Terminus"), improving the autorun logic and tape speedup of both CPCEC and ZXSEC, and adding the 64-colour ULAplus extension for Spectrum, as well as the ability to read SP and SZX snapshots.
  • 20210909 -- minor patch fixing bugs in the video render logic of ZXSEC, effectively ensuring that the multicolour effects seen in the tests ULA48, ULA128, FPGA48 and FPGA128 and the games made with the Nirvana engine ("Dreamwalker", "Multidude", "Stormfinch", "Sunbucket"...) show properly, and adding new audio extensions for CPCEC (Digiblaster audio) and ZXSEC (Covox $FB DAC) plus preliminary emulation of Pentagon 128 timings and (if the TRDOS.ROM file is available) the Beta128 disc drive and its TRD and SCL files.
  • 20210831 -- minor patch adding performance improvements to TZX/CDT playback and emulation of the Turbo Sound musical extension for ZXSEC, and removing the "Hard H-Hold" option from CPCEC, now useless thanks to further CRTC tweaks and the incipient emulation of the LA-7800 chip. The Windows version fixes a bug in joystick allocation, the SDL2 version understands UTF-8 filesystems and its user interface is a little more agile, and both versions can open GZIP archives and fix bugs in temporary file handling and YM file logging. CPCEC got a new icon.
  • 20210730 -- minor patch adding mouse support to the debugger and fixing bugs in the ASIC (modifying register 9 tests whether the new value is equal or lower than its counter, horizontal splitting doesn't draw garbage or retrigger IRQs: final scroller of "PhX") and the CRTC: reading the wrong port no longer returns the right value (secret part of "École Buissonière") and HSYNC events are filtered more carefully ("Chany Dream Demo 5", "Madness Demo", "Sub Hunter"...) unless the user prefers the old behavior ("Hard H-Hold" option). Several menu items have been relocated to set hardware traits and emulation options apart. CPCEC saves compressed memory blocks within snapshots unless "Strict SNA files" is enabled.
  • 20210626 -- minor patch fixing several format errors ("%i" in place of "%d" or "%u" and so on), a bug in the CRTC (3D cylinders part of "PhX" on CRTC3) and another one in the Spectrum Dandanator ("LD (DE),A" trap). Slightly safer snapshot block loading on both CPCEC and ZXSEC.
  • 20210624 -- minor patch adding Spectrum Dandanator support, and making both emulators able to load Dandanator cartridges from the command line and the key F3. Several heuristics ensure that the cartridges match the current system.
  • 20210609 -- minor patch adding lightgun emulation for CPC (Trojan, Gunstick and Westphaser on joystick port) and Spectrum (Gunstick on Sinclair 1 and Kempston ports), recreating a CRTC0 quirk (when R6==0 a single scanline is shown, rather than none as in other CRTC types) and improving the choice of the filler colour when half scanlines are on. The SDL2 version now handles mouse clicks when the button is up to improve consistency with other user interfaces. Tape acceleration options stick between sessions.
  • 20210526 -- minor patch aligning the X-Masking video effect to the right instead of the left. The debugger expressions accept three new operators: & (AND), | (OR) and ^ (XOR). XRF shows the output file's accurate byte length rather than just the megabytes, and running it without a target parameter prints the source video parameters and the expected size.

CPCEM 2021/05/24

  • 20210524 -- minor patch fixing bugs in film recording: field size errors on 64-bit machines, improper AVI header sound sample size on 8-bit output (both reported by Cpcitor), and accumulated dirt between multiple recordings within the same session. XRF also shows the length of the output file.
  • 20210522 -- minor patch fixing bugs in the ASIC (modifying the SSCR has an immediate impact; SSSL is checked when HCC==R1 rather than when HCC==R0; reported by NoRecess), the PSG (register 15 is valid, even if the hardware doesn't use it: the Plus demo "Phat" plays its music properly now), the Z80 (EI always delays the next IRQ, no matter the previous state of the interrupt enable flag, and OUTI sends the OUT signal during its last microsecond rather than during the second-to-last; "KKB First" demo needed both fixes to run correctly; reported by Hicks) and the FDC (errors imply delays that must be emulated: the original protected disc of "Bad Cat" accidentally relies on this; reported by Dlfrsilver). The debugger accepts very simple expressions (additions and substractions) when entering 16-bit values (address of "Go To", length of "Output"...) and the integer zoom allows 50% steps rather than 100% because the default size is technically 200% rather than 100%.

CPCEM 2021/04/28

  • 20210428 -- minor patch fixing bugs in the firmware INI handler (spaces must be trimmed on both sides of each string) and in several tape fastloaders, and adding inverse video 8-bit characters to the debugger's memory dump.

CPCEM 2021/04/18

  • 20210418 -- twentieth public release. Pixel and scanline filters are now saturation-based (colour aberration, desaturation) rather than luminosity-based (horizontal blur, shading). Fixed bug in XRF-to-AVI recording: VFW32 operations always assumed 16-bit stereo. The film recording options "High resolution" and "High framerate" now stick between sessions, and the first one also applies to BMP screenshots. Added support for block types 0x19 and 0x4B in CDT/TZX tape files, as well as the new disc option "Read-only as default" so the user can choose whether discs are by default read-only or read-write, and this option stacks together with the already extant "Strict disc writes". Added new option "Flip joystick buttons" to CPCEC so users can swap the value of the two CPC joystick buttons, as suggested by SB1903. PSG emulation now catches overflows, regardless of whether they're programming errors (music distortion in "Thing on a Spring") or done on purpose (pipe sound effect in "Thing Bounces Back"). Fixed bug in ZXSEC's Plus3 memory contention ("Firefly" disc release) and improved the beeper (oversampling: Utz's "Quattropic"). ZXSEC snapshot handling is now more strict or flexible (changing models as often or as seldom as possible) depending on the option "Strict SNA files".
  • 20210219 -- minor patch adding a new option, "Video: Blend scanlines" that handles Gigascreen effects (Spectrum demos "Mescaline Synesthesia" and "Tiratok", CPC demos "Batman Forever" and "Mad Leprechaun") and changing the sound synchronisation in SDL2. The AY chip noise generator is now a LFSR. SNA files saved from Spectrum Plus3 set bit 4 of byte 0x0C01E to state that the snapshot requires a Plus3 (Easter egg "Hello There I'm a +3"). The CPC debugger adds an information panel (key 'X') for Dandanator status, and its graphics viewer can show MODE 2 images.
  • 20210129 -- minor patch fixing a bug in the CPC PIO ("Super Cars" had stopped working in version 20210115) and improving CRTC1 compatibility (first part of "Ecstasy Demo").
  • 20210127 -- minor patch fixing bugs in the Spectrum timing ("LD (IX+n1),n2" and Z80_PRAE_SEND: thanks to Azesmbog for the FPGA test report) and the CPC tape analysis (conflict between Mikrogen and Hi-Tec).
  • 20210115 -- minor patch fixing a bug in the CPC PIO: "Inertie" sends a value to port A, then reads the same value back instead of receiving a PSG register or keyboard bits.
  • 20210114 -- minor patch improving Playcity stereo autodetection ("Alcon 2020" uses the left chip only), adding ROM simulation to Dandanator cartridges ("CPC Soccer") and fixing a bug in Z80 instruction CPI introduced in version 20210105 (RAXOFT tests) and another one in the CRTC1 VSYNC length ("Pheelone").
  • 20210107 -- minor patch fixing a bug in the ASIC's screen split trigger (SSSL must be checked when HSYNC rises, rather than when HDISP rises) and a glitch in the Win32 joystick support, and making the Playcity CTC more responsive.
  • 20210105 -- minor patch fixing a bug in video recording (it turned 44KHz stereo into 88KHz mono) and tape playback (16 and 24 bit WAVE files were improperly supported), extending the joystick support to handle directional controls (thanks to Pelrun for the Win32 and SDL2 code) and letting the Dandanator emulation modify the cartridge (configuration, savestates...) if the user allows it.

Changelog

  • 20201215 -- minor patch fixing snapshot loading on Spectrum Plus3 and extending the ULA's "snow" behavior ("Vectron") and scope ("Narco Police", "Robocop 3"). The SDL2 UI appends an ellipsis to filenames that are too long to fit within the dialogs.
  • 20201212 -- nineteenth public release. The Windows version can use DirectDraw instead of GDI, and the SDL2 version uses Textures instead of Surfaces: performance rises when hardware acceleration is available. Just in case, however, command line parameter `-!` and the menu option "Video: Software render" can be used to disable the hardware acceleration in systems where it's missing or performs worse than pure software. CPC bugfix: PSG handles register 14 separately, as expected by "Gremlins (v1)". Spectrum bugfix: 128K ghost ports are properly emulated, the demo "Tiratok" plays music at last. XRF lists the available codecs on Windows when launched without parameters.
    The software render is enabled by default, as the hardware mode is less likely to work on all machines, and in some cases (such as my desktop computer) it's actually less efficient than pure software. Disabling the software mode, then restarting the emulator, will show whether the video hardware provides 2D acceleration or not. You can always restore the software mode from the menu, or with the command line parameter "-!" if CPCEC becomes unlaunchable in the worst case.
  • 20201130 -- minor patch further extending ROM profile loading with four new fields: "type", "bank", "crtc" and "fddc".
  • 20201122 -- minor patch fixing a crash when using the SDL2 interface to save a file in the root path, and enabling automatic SDL2 detection on compile time.
  • 20201111 -- minor patch adding mouse tracking to the SDL2 interface and making XRF file recording less memory-consuming.
Abu Simbel Profanation (Dinamic Software, 1985)
  • 20201028 -- minor patch improving Issue-2 emulation on Spectrum 48K: "Abu Simbel Profanation" and "Rasputin 48K" work on 48K Issue 2 and fail on the other models, as expected
  • 20201024 -- minor patch solving a problem with the SDL_WINDOWEVENT_EXPOSED event and inverting the black/white bits in ZXSEC's graphics viewer.
International Karate + (System 3 Software Ltd., 1987). I zielony Neptun 156;)
  • 20201022 -- minor patch adding mouse wheel support to the SDL2 user interface and an option to set whether disc write conflicts in CPCEC and ZXSEC are strict (they raise errors) or relaxed (they do nothing).
  • 20201020 -- minor patch fixing a bug in the Dandanator support (the "LD (IY+n),A/B/C" operations must work with any "n" value, instead of just 0: thanks to Spirax for the report) and another one in the CRTC (counter HCC is 8 bits long: "Camembert Meeting 4 Demo" stops showing a line of garbage between the top and the middle panels), adding SDL2_DOUBLE_QUEUE as an optional SDL2 compilation flag (some systems need an audio buffer longer than the default 8 frames) and using a different pixel pattern when both X-Masking and Y-Masking are enabled.

Swords Of Ianna (2020, Retroworks). Jak zwykle Retroworks zrobiło tytuł, który koniecznie trzeba zobaczyć. CPCEM z włączonymi filtrami GFX

Changelog

  • 20201010 -- eighteenth public release. Fully rewritten CRTC logic, with an internal event system that extends demo compatibility (for example "Chapelle Sixteen", "Madness Demo" and "S&KOH" for CRTC1) and a fully multiplexed Plus sprite renderer. More disc protections (ERE, UBI) are supported, WRITE DELETED DATA updates the corresponding flag in the sector table. New Dandanator support, read-only ("Sword of Ianna"). Preliminary Playcity support, limited to the two extra PSG and the NMI trigger. New video recording based on an intermediary format XRF, and including a tool allowing to convert it into AVI files. Improvements in the SDL interface, with a bigger font (12px rather than 8px) and vertical alignment in menu keyboard shortcuts. Added new debugging functions (looking at graphics in memory with key "W", trapping the opcode $EDFF as a breakpoint, etc.) and moved breakpoints from "T" to ".". Removed CPCEC.ELF and ZXSEC.ELF as they're bound to a single OS (Linux Mint 18 32bit) and the user must compile the binaries anyway. Moved the configuration files in non-Windows systems from CPCEC.INI and ZXSEC.INI to .cpcecrc and .zxsecrc as customary on Unix.
→ NOWSZY [Z80] CPCEC/ZXSEC XV 20/06/2020

Changelog

  • 20200622 -- minor patch reducing memory footprint (extra ROM memory is only allocated if the user loads a "profile"), rendering SYNC signals as black rather than as the current border, and fixing the 3D cylinders part of "PhX" on CRTC1; the "ball worms" and the final scroller stay bad on CRTC3 and CRTC4, though.
  • 20200616 -- minor patch adding several tape analyses and removing the patch that shortened the initial delays (it caused problems). Several changes in SDL2 (fewer warnings, disc drive cache in Win32) and in the Z80 debugger (more content: 256 bytes of memory dump and 32 bytes of stack).
  • 20200606 -- minor patch with surround sound: the user can set the channel separation to 0% (mono), 50% (surround) or 100% (stereo).
  • 20200603 -- seventeenth public release. Added stereo sound. Fixed a bug in the CPC PIO (the read-only mode of port A allowed writing), another bug in the tape analysis (CPCEC: the algorithm for TITUS caused trouble in "The Blues Brothers"; ZXSEC: Speedlock5 didn't recognize the heading noise; both systems add patches to shorten the initial delays), another one in the loading of CPC snapshots (a snapshot saved on PLUS hardware without the "CPC+" block showed a completely black palette), another one in the Z80 debugger (the command 'P0 could generate an infinite disassembly), another one on tape handling (reading a WAV file must use >128 as reference instead of >=128) and some problems in Win32 (the screen stopped updating after pausing, switching windows in and out) and SDL2 (boot message errors weren't shown; the filename sorting algorithm was slow).
  • 20200509 -- minor patch improving the synchrony between Z80 and video on ZXSEC: the ULA48 test already worked before, but ULA128 had problems; now both work well. Added the option -W (use the full screen rather than a window) and improved the SDL2 handling of bigger windows.
  • 20200504 -- minor patch focused on the SDL2 toolkit: fixed a bug when confirming overwriting files, and improved file browsing across directories by pointing by default to the previous directory.
  • 20200503 -- 20200503 -- minor patch improving the behavior of the Z80 operations INI, IND, INIR, INDR, OUTI, OUTD, OTIR and OTIR: the 2012 RAXOFT tests (Z80CCF, Z80FULL and Z80MEMPTR) score zero errors. Slightly more precise automatic frameskip.
  • 20200430 -- sixteenth public release. Now you can compile CPCEC and ZXSEC with SDL2 (featuring its own graphical user interface) for multiple operating systems thru the option -DSDL_MAIN_HANDLED; the precompiled files CPCEC.ELF and ZXSEC.ELF for 32bit GNU/Linux are included, too. New support for extended ROM profiles through INI files enumerating up to 257 16K ROM blocks. Further Z80 tweaks: the new error rates of ZXSEC in the 2012 RAXOFT tests are 8/152 Z80FULL, 5/152 Z80CCF and 0/152 Z80MEMPTR.
  • 20200420 -- minor patch fixing the HSYNC signals' black stripes from "Chany Dream End Megademo" on CRTC 1, "Onescreen Colonies" on CRTC 0, etc., as well as the value of MEMPTR in JR cc,$RR and DJNZ $RR and the logic of BIT n,r,(IX+$XX): the error rates of ZXSEC in the 2012 RAXOFT tests are Z80FULL 10/152, Z80CCF 70/152 and Z80MEMPTR 4/152.

Changelog

  • 20200406 -- minor patch adding partially multiplexed PLUS sprite rendering: "Synergy 4" recovers its top left sprites.
  • 20200404 -- minor patch fixing the DMA handler (all commands but LOAD can be combined together) and removing several "kludges" for PLUS but the one for "Black Sabbath": thanks to Norecess464 for locating the bug. Also, -C now becomes -C0..4.
  • 20200331 -- minor patch providing further fixes for Plus demos "CRTC3" and "Synergy 4" (top left sprites disappear after few seconds, though) and adding the command Shift+Space (skip scanline) to the debugger.

Intro Eerie Forest (Logo System, 2017) - tryb emulacji Amstrad Plus

Changelog

  • 2020/03/14 -- first anniversary! minor patch fixing issues in the demos "CRTC3" and "Eerie Forest" for Amstrad Plus.
  • 2020/03/07 -- minor patch avoiding a hang in globbing(), improving snapshot compatibility (WinAPE and ACE employ slightly different CPC+ blocks) and removing several useless details. The optional firmware packages now include the corresponding cartridges.
  • 2020/02/29 -- fifteenth public release. Added support for Amstrad Plus hardware: extended colours, soft scrolling, hardware sprites, programmable raster interruptions, DMA channels, ROM cartridges, etc. Added fifty more tape schemes to speed up the reading of bytes and even whole blocks. Improvements in the disc drive emulation: new discs (by default the DATA format shared by CPC and Spectrum +3) can be created on the fly, emulation of protected games from Design Design ("2112 AD"), The Edge ("Palitron"), Titus ("Prehistorik" and "Moktar/Titus the Fox"), bugfixes (READ ID: "5KB Demo 3", "Daley Thompson's Olympic Challenge" and "Turbo Copy III"; FORMAT TRACK converts old-style MV - CPC discs into new-style EXTENDED ones, and cleans up useless data at the end of the disc). CPCEC honours the RAM size (up to 576k) and CRTC type stated by a snapshot ("Postscript" demo) and so does ZXSEC, that can read Z80 snapshots now and allows 48K SNA files to be either strict (the original format) or relaxed: 128K headers on 48K data. Control-F2 avoids accidental recording of snapshots after a reset. Fixed a bug that happened when combining Y-Masking and Half Scanlines. Extended ZIP archive support to handle pipeline-generated (i.e. the final headers are the right ones) archives. Sources are distributed together with the binaries instead of being delivered upon demand.
→ NOWSZY [Z80] CPCEC/ZXSEC XIV 01/01/2020

Changelog

  • 20200101 - minor patch fixing a regression in CRTC0 caused by the previous patch ("Scroll Factory", intro of "Pinball Dreams", "Overflow Preview: Part 1") and improving its heuristics ("Overflow Preview: Part 3").
