[[File:ACE.png|thumb|German GUI - Main window]]'''ACE''' is a high quality [[Amstrad]] CPC/CPC+ emulator written by Philippe "[[OffseT|OffseT]]" Rimauro. It is developed exclusively for [http://www.morphos.de/ MorphOS], but .<br />[[PulkoMandy]] is maintaining a port (still beta and based on older version) for [https://www.haiku-os.org/ Haiku].
ACE is not based on any existing emulator and was coded from scratch, using a real CPC as a reference in order to provide one of the best Amstrad CPC emulator ever. <br />Most of the games and demos for both CPC and CPC+ are working perfectly; the quality of the emulation is often superior to what the existing CPC emulators on PC/Windows can produce.
In addition to the high quality emulation, ACE features full screen and overlay display (including 50Hz display), editor and analyzer windows for all emulated CPU and chipsets, advanced breakpoints management, a very powerful set of AREXX commands for cross-development, a plugin interface... , and much more...
Moreover, ACE is fully translated in French, Spanish, German and English and is still under active development.
* Accurate emulation of the keyboard (including ghost keys when pressing more than three keys at once).
* Automatic keyboard remapping can be activated if your are using ACE with a keyboard layout unknown by the original CPC firmwares.
* Plugins interface to support virtually any external device (ACE comes with built-in plugins for joysticks, light guns, soundplayer, printer and mices). Additional plugin is available for [[Albireo|Albireo expansion card]] emulation.
== Graphical interface ==
ACE MUI graphical interface is designed to be versatile and very easy to use, and everything is always updated in real time to match the actual emulator state.
* Simple and modular configuration of the CPC profiles to emulate using tool types (from Ambient) or arguments (from CLI).
* Ability to change the CRTC type or the screen monitor model on-the-fly without having to reset the running program.
* SNA and DSK files management (all of them!) with automatic on-the-fly detection and fix of the corrupted DSK.
* CPR files management for CPC+ cartridges(including support of extended cartridges up to several hundreds on megabytes).
* Overlay support with real pixel aspect ratio.
* Full screen support with the ability to choose the graphic mode to use in order to get back the 50Hz smoothness if your screen monitor can do this.
* Screen monitor settings window (type, brightness, vertical hold).
* Sound volume control.
* Online help and MUI's bubbles help available everywhere to help the beginners* Localized in French, German and English (including the help).
== Programmable interface ==
ACE is designed to be expandable and controllable. You are not limited to the core emulation and can you easily integrate it in any cross-development tool chain.
* Handling of expansion plugins that allow anybody with some C language knowledges to add support for expansions connected to joystick, printer or expansion CPC port (except for memory management). By default are provided plugins to support:
** Both [[joystick]]s (up to three fire buttons) using real devices plugged on the host machine (using USB or whatever).
** [[Digiblaster]]|Digiblaster/Soundplayer]].
** [[Printer]] (redirected to a file).
** [[Kempston Mouse]].
** [[Trojan Light Phazer]].
** [[West Phaser]].
** [[Albireo]].
** CycleCounter (developer helper).
* Support of an AREXX interface which allows to fully control the emulator and to manipulate its memory, in order to automate things and more, or to use ACE as a powerful cross-development station.
