Kevin Thacker released a new work in progress version of his Amstrad CPC emulator called Arnold. For this release he did a huge amount of testing, especially for the FDC routines, and wrote a lot of tests to ensure that the emulator behaves just like the real machine.

You can get a precompiled version here: http://www.cpctech.org.uk/setup.zip

And for the Linux and Mac users (and Windows users :-)) – you can get the source code here: http://www.cpctech.org.uk/arnoldsrc.zip

Here is the changelog for this version (be prepared… it is huuuuuuge):

SAMdisk is a tool to convert floppy disks into various disk images which can be used in emulators. It works with almost all PC floppy controllers and supports also some copy-protected formats. It requires that you have fdrawcmd.sys, a low-level floppy disk driver, installed on your system.

You can download the latest version from the SAMdisk website.

Version 3.8.10 (2017-05-14)

  • added read and write support .qdos (QL) disk images
  • added –irregular option for blind output image if first track isn’t regular
  • added –fill to set filler byte for regular formats
  • fixed setting perpendicular mode for 1Mbps data rate
  • fixed reading directly to single-sided formats from a:/b:
  • fixed short data indicator showing on no-data sectors
  • fixed raw output not using source format fill byte for missing sectors
  • changed raw output to allow blank head 1 to mirror head 0 format

OffseT released a new version of his emulator for the MorphOS operating system. It emulates the Amstrad CPC old generation and the Amstrad Plus, too. The emulator was written from scratch, so it isn’t just a port of an existing open source Amstrad CPC emulator. Due to its very precise audio and video renderings, ACE should be your first choice to watch demos – if you have a MorphOS system around.
If you are a MorphOS user and want to use your Amstrad CPC software under MorphOS, don’t hesitate and download it from the ACE homepage.

Changes:

  • Reworked layout of several windows.
  • Updated german catalog (Stefan ‘polluks’ Haubenthal).
  • Added new icons for GUI, drawers, plugins and filetypes (Mathieu ‘Hwikaa’ Delaruelle).
  • Re-optimized emulation speed that had deteriorated in version 1.13 (ACE is now 5% faster).
  • Greatly improved CRTC 0 emulation.
  • Fixed some minor issues in emulation of CRTC 1, 3 and 4.
  • Improved internals to ease portability on AmigaOS and AROS.
  • Added support for breakpoints on Maxam and WinAPE BRK opcodes.
  • Improved some AREXX commands.
  • Updated the cross-development examples to use vasmz80_oldstyle assembler instead of pasmo.

A new version of the HxC floppy emulator software for Windows was released in version 2.1.6.0. Besides some non Amstrad CPC releated features, it contains the possibility to add DSK files to the batch converter export list now.
The HxC floppy emulator is a device, which emulates a floppy disk systems by using disk images, which are contained on a SD card. It is the defacto standard for Amstrad CPC users to replace the internal or add a new 3″ drive. Thanks to Norecess’ great HxC floppy configuration software, it is nicely integrated into the system of the Amstrad CPC and very easy to use.

You can download the latest version from the HxC floppy emulator homepage.

Changelog for v2.1.6.0

  • XML format definitions: Korg DSS1 DD disks added.
  • XML format definitions: Emax II disks added.
  • Command line tool: USB loader -> Raw loader added.
  • Amstrad DSK file added to the batch converter export list.

A new version of Sugarbox, a Amstrad CPC emulator for Windows, was released. The main features of the new version are emulation optimizations, command line switches, sound emulation improvements and various other improvements.
Be sure to test the new version of the emulator and download the latest version from http://sugarbox.free.fr.

Changelog:

  • [Emulation]: Add some optimizations. MAX speed should be faster (about 100% gain from v0.26).
  • [Emulation]: Remove memory leaks in IPF writing process.
  • [Config files]: Fix the ‘-’ and ‘_’ for french keyboard: « From scratch » now autorun properly.
  • [Display]: Screenshots are fixed: No more unwanted black line at the top.
  • [Dump support]: Fix the code used to compute multi revolution dump, to be more reliable (when a revolution is wrecked, dont use it).
  • [FDC]: Lots of fix in the FDC: The ‘acid tests’ of arnoldEmu are almost all corrects now.
  • [FDC]: Fix some bugs when reconstructing the tracks (fix some dump of « Le Necreomancien », and various CTRaw files also).
  • [FDC]: The ‘Flip’ fonction (used to flip double sided dumps) is now working correctly. Double faces IPF are now working.
  • [FDC]: ’10′ bits used for bit synchronisation can be in a smaller number: 40 bits are enough to consider the PLL as correctly fixed between clock/data bits.
  • [General]: Fix a deadlock that occurs when a command is used during a dump disk is read.
  • [General]: Fix the autotype feature : the feature is more relevant. Also, the « | » character is correctly rtanslated to ‘ù’ on french keyboard.
  • [General]: Add a function to recording every frame into a screenshot.
  • [General]: Autorun feature is a bit more reliable (more rules added).
  • [General]: Added some command line switches: -sn xx (load xx as a Snapshot file), -drivea xx to set xx into drive A, -driveb (same for drive B), fullscreen to start in full screen mode, -config xx to load xx as config file, -command xx to run xx as basic command at start.
  • [GUI]: Fix the incorrect update of « Save as.. » menu when inserting a disk.
  • [Multiface II]: Add preliminary support for Multiface II (no config yet).
  • [PPI]: Rewrite most of the 8255 implementation. Now run the ‘acid test’ properly (when it have meanings).
  • [PSG]: Correct lots of bugs (sound is now a LOT better, and digitized sound works correctly). Fix Dick tracy, Antiriad, Crazy cars 2, and probably a lot more!
  • [PSG]: Also run the ‘acid test’ of PSG correctly.
  • [Z80]: Support for NMI added.
