Amstrad CPC emulator

Legacy Xcpc

cover

For your information, this page only exists just for historical reasons and is about the legacy version of Xcpc, before the v0.50.0.

Xcpc is a portable Amstrad CPC 464/664/6128 emulator written in C. It is designed to run on any POSIX compliant system having an X11 server, including Linux, BSD and Unix.

Note there is absolutely no support for Microsoft Windows operating systems and there never will be. Please do not ask me to add such functionality.

Xcpc is designed to emulate classic range of the Amstrad CPC systems:

The Amstrad CPC+ range and the GX4000 console are not currently emulated and likely will not be.

FEATURES

Here is a non-exhaustive list of supported features:

  • A simple X11 Intrinsic user interface.
  • A complete Athena user interface.
  • A complete Motif-2x user interface.
  • A complete Gtk+-3.x user interface.
  • Full X11 with XShm extension.
  • Adaptative frame-rate.
  • Full Floppy disk images support (.dsk).
  • Full snapshot support (.sna).
  • Drag and Drop support (.dsk, .sna).
  • Keyboard emulation (qwerty, azerty).
  • Joystick emulation with the numeric keypad when numlock is disabled.
  • Joystick emulation by pressing the « Home » or « End » key (then use arrows + left-ctrl + left-alt).
  • Joystick support under Linux (up to two hardware joysticks).
  • CPU: Z80 with full documented and undocumented instructions.
  • VGA: Video Gate Array 40007/40008/40010, complete support.
  • VDC: CRTC 6845, almost complete full support.
  • PPI: PPI 8255, almost complete full support.
  • PSG: AY-3-8912, partial support (actually no sound is produced).
  • FDC: FDC 765A, complete support.

The emulator lacks some features. Here is a list of the most wanted features:

  • Sound support.
  • Wayland support.
  • A Qt user interface.
  • A built-in assembler.
  • A built-in debugger.

REQUIREMENTS

Xcpc requires an X11 server and either the X Toolkit Intrinsics or the Gtk+ library.

The user interface is selected at compilation time and can be either Intrinsic, Athena, Motif-2.x or Gtk+-3.x.

Note: although Xcpc can use Gtk as frontend, the Wayland graphics server is not yet supported but is planned.
