Voici CPCEC et ZXSEC de CNGSOFT. J'ai aidé César pendant ces derniers mois à la conception de cet émulateur, ceci dans le cadre de son examen universitaire.

http://cngsoft.no-ip.org/cpcec.htm

Ses points forts :

* une légèreté et une rapidité incomparable. Fonctionne avec 4mo de RAM seulement sur un PC, et un processeur à 400mhz + une résolution minimale de 800x600.

* Compatible avec 100% des jeux cassettes sortis sur Amstrad, y compris les protections MBC, keytones et ainsi de suite.

* La partie sonore est la plus fidèle de tout les émulateurs existants.

* Accélération du chargement des cassettes, reconnaissance automatique du loader utilisé

* Fonction Drag'n'Drop : on glisse les fichiers sur la fenetre de l'émulateur et hop !

* Supporte les fichiers CDT, DSK, CSW, WAV. format CTRAW et IPF à venir

Point à améliorer :

* ajout d'un menu

* précision du FDC (un grand nombre de jeu déjà passent, seuls certains avec des protection particulières restent à supporter)

* précision du CRTC (note, tout les jeux commerciaux passent, seules les démos, et les derniers jeux comme Pinball Dreams qui utilisent le CRTC en profondeur ont un problème).

Citer :
20190526 -- minor patch fixing a bug in autorun mode: opening menus and switching windows cancelled the automatic keyboard.
20190524 -- tenth public release. Added support for CDT/TZX file blocks 0x24 and 0x25 (loop start and ending) (cfr. BATMAN.TZX), fixed bugs in the handling of weak sectors in DSK files (cfr. "Titus Classiques"), YM file recording is reentrant, fixed a bug in INI files with empty fields and added the option "autorewind <0|1>" to rewind (or remove) a tape when playback reaches the end.
20190430 -- ninth public release. Softer B/W Spectrum palette; fixed bug in FDC sector size calculation if GAP datas are stored (Loriciels' discs); added simple memory contention to ZXSEC ("Amaurote", "Black Lamp", "Puzznic", "Sly Spy", "Zub"...).
20190419 -- eighth public release. Added options for image and sound interpolation; tape automatically rewinds itself when it reaches the end (à la FUSE); fixed a bug in TZX files that store 0 instead of 8 in the "used bits" field, another bug in CUSTOM INFO blocks in TZX files, and another one when ZXSEC loads a 48K SNA file in Plus3 mode (users should manually switch to a safe model beforehand anyway). INI files now remember the names of the last used files.

20190731 -- eleventh public release. Added a new UI-based debugger (typing commands is no longer needed) and support for ZIP archive reading based on PUFF.C from the ZLIB project, upgraded GCC to 5.1.0 and removed all `inline` tags (they did more harm than good), and generally reworked all internals to make them OS-independent. Several details improved as well: the file selector fixes a bug in Win10, "browse tape" dialog shows the file name, Spectrum +3 automatically becomes +2A to load tapes, `auto rewind` shows up in Edit menu and fixes bugs in CSW files, and sound emulation has improved, for example "Terminus" on CPC plays sound and "Agent X II" on Spectrum is no longer noisy.

20190809 -- minor patch restoring the "silent" discarding (i.e. without error codes) of write operations in read-only discs and allowing the automatic booting of IBM-formatted discs.
20190817 -- minor patch fixing a crash when booting tapes right when the automatic frameskip kicks in.
20190831 -- minor patch fixing several bugs (booting two-sided discs with FLIP SIDE option on, recording snapshots or tapes after loading a snapshot or tape from a ZIP archive), improving several details (loading snapshots with memory compression, emulating up to 576 kB RAM) and redefining the menus (Edit is divided into Edit and Settings, Image and Sound become Video and Audio, new video filter functions...) and the command line: "-+" now limits the zoom to integer values; "-!" inherits the option of hiding the menu.

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.

20191117 -- thirteenth public release. More precise emulation of type 1 CRTC (by default instead of 0) in CPCEC ("From Scratch", "Pinball Dreams"...) and 48K memory contention in ZXSEC ("Starion", "Black Lamp"...). CPCEC also allows choosing the length of the V-hold signal (for example "Thunder Blade" needs a short signal) and whether horizontal sync must be flexible ("Batman Returns", "Pinball Dreams"...) or not ("CPC 30th Anniversary Megademo", "PhX"). Unfortunately, some demos that worked well in past versions now suffer problems that cannot be solved by selecting another CRTC. Removed third joystick button in CPCEC, no real joystick ever included it. The ZXSEC joystick is Sinclair 2 by default.
20191130 -- minor patch fixing a bug when running CPCEC and ZXSEC on a screen shorter than 600 px, another one when recording a WAV file, and another one in the port logic of CPCEC ("Knight Rider", OUT &0088,&88 must not reach the Gate Array, but "Hero Quest", OUT &00C0,&C0 must reach it). The CRTC types 0 and 2 have improved ("Face Hugger Ultimate Megademo": "Tantrum", "5KB Megademo 3", "Power System Megademo": "Glooms"...) but cannot handle "Pinball Dreams" yet, unlike CRTC 3 and 4, that together with CRTC 1 support this game now.
20191227 -- fourteenth public release. Visual improvements: the green screen palette is closer to the original, the vertical filters ("Y-Masking") are compatible with the interlaced modes, mixing X-Masking and Y-Masking together shows a checkered pattern. Internal improvements: the new traits of the CRTC registers 3 and 9 and the delays between the Gate Array, the Z80 and the CRTC finally can emulate "Pinball Dreams" as a whole for all the CRTC types and solve the problems in several demos ("Scroll Factory", "Still Rising", parts of "The Demo"...) and games ("Action Fighter", "Storm Warrior", "Usagi Yojimbo"), although some titles still need particular CRTCs ("PhX" CRTC0, "Onescreen Colonies" CRTC1, etc.) to work correctly.
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!
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").

20200229 -- 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.

20200314 -- first anniversary! minor patch fixing issues in the demos "CRTC3" and "Eerie Forest" for Amstrad Plus.
20200307 -- 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.

Además CPCEC continúa evolucionando. Ya he resuelto casi todos los problemas de temporización de "Prehistorik 2", "1st Plus Demo", "CRTC3" (¡todas las partes!), "Eerie Forest" y "Synergy 4".

coucou, on discute pas mal sur le discord pour faire avancer les choses donc un grosse mise à jour est à venir
surtout les dernières modifications qui étaient en fait des patchs pour faire fonctionner telle ou telle démo -> poubelle
le système de déclenchement des interruptions programmables a été revu pour coller plus avec le comportement décrit dans les specs de Kevin T.
en travaillant sur les délais des split-rasters selon l'instruction qui fait l'écriture, on a aussi relevé que les lectures/écritures 16 bits n'étaient pas atomiques
voilà donc ça bosse :wink:

Lors de la publication du package CHIPNSFX, j'ai publié (enfin) la seizième version publique de CPCEC et ZXSEC , avec la prise en charge tant attendue de SDL2 qui a permis de compiler et d'exécuter des émulateurs sur GNU / Linux (dans ce cas LinuxMint 18.3), MacOS et même Raspberry Pi.
Enfin, j'ai publié aujourd'hui un patch mineur de CPCEC et ZXSEC dont les deux bénéficient, mais qui est plus facile à voir en action dans le second: le package de test RAXOFT 2012, qui limite l'émulation du Z80, atteint enfin 100 % Succès: les derniers plantages restants, qui étaient concentrés sur le jeu d'instructions d'entrée et de sortie de bloc (INI, IND, INIR, INDR, OUTI, OUTD, OTIR et OTDR) ont définitivement disparu.


Citer :
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.
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.
