Getting Started

Getting XQEMU

Download for Windows: The latest, pre-built release version of XQEMU for Windows can be downloaded here.

Linux and macOS users will need to build XQEMU from source see Building XQEMU from Source.

Required Files

XQEMU is a low-level, full-system emulator which emulates the actual hardware of the Xbox; this means that in order to actually run XQEMU, you must have a copy of the stuff that a real Xbox needs when it turns on:

  1. The MCPX Boot ROM image
  2. The flash ROM image (aka BIOS)
  3. A properly-formatted hard disk drive image
  4. Game disc image(s)

Unfortunately, distributing some of these items would violate copyright laws, so you'll need to acquire them on your own.


The XQEMU project does not endorse or promote piracy. We don't link to the copyrighted files, or discuss how to acquire them. The best way to acquire these files is to dump them from your real, physical Xbox. Please don't ask us how to get them.

MCPX Boot ROM Image

MD5 (mcpx_1.0.bin) = d49c52a4102f6df7bcf8d0617ac475ed

If your MCPX dump has an MD5 of 196a5f59a13382c185636e691d6c323d, you dumped it badly and it's a couple of bytes off. It should start with 0x33 0xC0 and end with 0x02 0xEE.

Flash ROM Image (aka BIOS)

Xbox 1.0 compatible bios (cromwell, 3944, 4034, 4036, ...). You can use a retail or debug image. Just like a real Xbox, running an unmodified retail bios will not allow booting unofficial software.

People have reported most success using the modified retail "COMPLEX 4627" BIOS.

Retail BIOS
1M dump: MD5 (3944.bin) = e8b39b98cf775496c1c76e4f7756e6ed

or sometimes

256k dump: MD5 (3944.bin) = 542c62cb976a4993c8c5027dff9638ce
Debug BIOS

People have reported success with the 'COMPLEX 4627' modified debug bios. It's convenient to note that this bios does not necessarily require a populated hard disk image to load an application from DVD (though an empty drive still needs to be attached), so you can skip the next step in some cases.

v1.0.2 1M dump: MD5 (Complex_4627Debug.bin) = 19b5c6d3d42a707bba620634fe6d4baf

or sometimes

1MB dump: MD5 (complex_4627debug.bin) = e8dd61cc6abdbd06aac185e371312dc1

Hard Disk Drive Image

You have options:

You can use a pre-built 8G Xbox HDD image, free of any copyrighted content, and only containing a dummy dashboard. You can download this image from here!


By design, this particular drive image does not contain the official Xbox dashboard, but instead contains only a dummy dashboard. Because of this, you may see an error message when starting XQEMU with an unmodified retail BIOS image due to the system failing to find a properly signed dashboard.

If you would like to change your dashboard (perhaps to the official retail dashboard, or any alternative dashboard), or copy additional files over to the Xbox HDD, you can start XQEMU, using a modified BIOS image, and a disc containing an alternative dashboard. Then you can either install that dashboard, or connect to XQEMU using FTP to transfer your desired dashboard files to the HDD.

Option 2: Image your real Xbox HDD

This is the most authentic way to do it. Unlock your drive, connect it to a computer, and dd the entire contents of the drive straight to a file. This file can be used as-is with XQEMU.

Option 3: Build a new HDD image from scratch

You can also create an Xbox hard-disk image using XboxHDM. Directions on how to do this can be found here.

Running XQEMU

XQEMU is launchable via the command-line interface (though a GUI launcher is in development!) You can launch with the following command:

./i386-softmmu/qemu-system-i386 \
    -cpu pentium3 \
    -machine xbox,bootrom=$MCPX \
    -m 64 \
    -bios $BIOS \
    -drive index=0,media=disk,file=$HDD,locked \
    -drive index=1,media=cdrom,file=$DISC \
    -usb -device usb-xbox-gamepad

Of course, on Windows the executable path will have a .exe extension. If launching a pre-built binary from AppVeyor, replace ./i386-softmmu/qemu-system-i386 with xqemu.exe.

Replace the variables $MCPX, $BIOS, $HDD, and $DISC with the appropriate file paths or define them as variables in your shell.

The Xbox boot animation sequence can be bypassed by adding the ,short-animation option to the -machine switch above.
