Arnold is a CPC Emulator original emulator written and maintained by [[Kevin Thacker]].

Arnold aims for maximum emulation accuracy across The newest version is 13/05/2017. This is the whole CPC "work in progress"/"wip" version which is already very advanced and CPC+ range, as well as the [[KC Compact]]is more accurate than most existing emulators. Different [[CRTC]] types can be selected as well as various other aspects of This is verifable using the emulated machine'acid test' test programs which are freely available for others to use to improve their emulators.

While early versions of Arnold where written using x86 assembly, more recent versions is being actively developed and there are written in portable Cupdates to the code almost daily. This resulted The work in ports progress version uses SDL for MacOSthe display, MacOS audio and input and wxWidgets for the GUI. It is built with cmake and now all versions (Mac OS X, Linux, /Unix and other platformsWindows) have identical functionality and interface. While every port of  Arnold aims for maximum emulation accuracy across the whole CPC and Plus range as well as the [[KC Compact]], Aleste 520Ex and the GX4000. The emulator has various devices that can be enabled and there is own native user interface, extensive configuration possible.  The following devices are emulated and useable:* [[AMRAM2]]* [[BrunWord | Brunword mk2 and mk4]]* [[Hackit]]* [[Hexam]]* [[MegaROM]]* [[MultiPlay]]* [[Rombo_Rombox]]* [[Vortex_Expansions_RAM_card]]* [[CPC4MB]] The following are partially emulated:* [[SYMBiFACE_II]] (RTC not emulated and data for IDE device data is transient)* [[UIDE_Universal_IDE_adapter_cards_for_Z-80_computers]] (IDE device data is transient)* [[X-Mass]] (IDE device data is transient) The following are in progress:* [[X-MEM]]* [[Dk'tronics_memory_expansion]] (256KB RAM and 256KB Silicon disk are in progress) The following are based on hacking the ROMs so need much more testing* [[Vortex_Winchester_Drive]]* [[Dobbertin_Harddisk]]  Previous versions shared the same emulation core remains , but each port was managed separately and had different user interfaces. The Windows port made by Kevin, Apple Macintosh port by [[Richard Bannister]] and Linux port by [[Nurgle|Andreas Micklei]]. There is also a Linux "nurgle" version which contains patches and improvements over the same accross original by Elmsoft and Nurgle. The initial version was written in C on Windows and used DirectX. Previously to this there was A-CPC, an Amstrad emulator for Amiga also by Kevin Thacker.  == Arnold WIP == * Source : [http://www.cpctech.org.uk/arnsrc.zip Arnold wip source] - May 13 2017* Windows: [http://www.cpctech.org.uk/setup.zip Installer for Windows ] - May 13 2017* MAC : [http://www.cpctech.org.uk/arnold.dmg Arnold for Mac] - August 2017* deb package for Debian/Ubuntu: [http://www.cpctech.org.uk/arnold_1.0.0-1_amd64.deb Arnold for Linux] - August 2017* rpm package for Fedora/SuSE: [http://www.cpctech.org.uk/arnold-1.0.0-1.x86_64.rpm Arnold for Linux] - August 2017 == "Acid tests" == Arnold comes with a collection of tests which are used to verify it's operation against real CPC, Plus and expansions.These tests aim to test every feature and bug of the hardware including rarely used ones.It also attempts to show the differences with the ICs used by the Amstrad which came from different versionsmanufacturers (8255, CRTC etc) * Acid tests: [[File:Acid Tests Suite.zip]] [http://www.cpctech.org.uk/test.zip Acid tests]
