Chipsnapper:

'''XEO3''', also known as '''Fission''', is Microsoft's Xbox / Xbox 360 emulator for Xbox One.

It was eventually discovered that Fission is actually just a repackaged [[Fusion]], running inside a 360 emulator.
360 Shaders are recompiled to D3D11 Durango format by '''BackgroundShaderCompiler.exe'''.

Some critical shaders are shipped alongside the executables.
A '''LaunchArguments.txt''' file next to '''Emu.exe''' provides unique run parameters for each game.

Chipsnapper: /* Steps to activate Soundtrack Easter Egg */

== Hidden features ==

=== Hotkey to switch to HD modes ===

Latest Xbox Dashboard (5960) force 480p display mode:

Press and hold Left trigger, right trigger, and both analog stick buttons.

The normally displayed 480i dashboard will switch to 480p output while using
the Xbox High Definition AV Pack or cable.

Repeat button combo to toggle between 480p and 480i.

=== Music visualization in fullscreen ===

Press {{input-y}}, {{input-x}} while playing audio CDs or soundtracks stored on the HDD to display full-screen geiss-like music visualization. Or, press "INFO" button on the DVD Playback Kit remote.

Only visible with DVD Playback Kit and Remote:

#Start playing a song using either the Xbox controller or playback kit remote.
#Press {{input-y}}, {{input-x}} on the controller or "INFO" on the remote to get the full screen visualization.
#Here's the part that requires the DVD Playback Kit remote. Press "STOP" or "PAUSE" (you cannot use the controller to stop the music to see it as doing so goes back to the Music Playback menu with the small visualization area). Once the music visualization pattern dies down, a full-screen swirling starfield pattern appears. After some time passes, the screen will be filled with a changing burst of solid color where you can make out the wireframe spinning globe seen encompassing the main dashboard background. The burst of color fades to black leaving the swirling starfield. The cycle repeats with a random changing solid color burst which fades to the swirling starfield{{FIXME|reason=replace lengthy explanation with a video of this}}.

Not quite true about needing the remote control, if playing a CD while full screen visualization is displayed, press the eject button on the front of the Xbox console.

=== Soundtrack name Easter-Egg 1 ("<<Eggsβox>>") ===

Stored in settings_adoc.xip (which is actually an XBE file)

==== Steps to activate Soundtrack Easter Egg ====
# Insert an audio CD and let it begin to play.
# Stop the disk and step back (press B) in order to "Copy" selected tracks of the CD to the hard drive.
# When the track list comes up, "Select All" and continue.
# Choose "New Soundtrack" as the destination for your selection.
# Enter the name of your soundtrack exactly as follows: <<Eggsβox>> including the less than, beta, and greater than symbols.
# After you have entered the title, select "Done". A "Thank You" message starts which is followed by a scrolling list of the Xbox Team members.
If you press a button on the controller or let the message play through to the end -- the Xbox reboots.

=== Soundtrack name Easter-Egg 2 ("Timmyyyyyyyyyyyyyyyyyyyyyyyyyy!") ===
==== Steps to activate Soundtrack Easter Egg ====
# Insert an audio CD and let it begin to play.
# Stop the disk and step back (press B) in order to "Copy" selected tracks of the CD to the hard drive.
# When the track list comes up, "Select All" and continue.
# Choose "New Soundtrack" as the destination for your selection.
# Enter the name of your soundtrack exactly as follows: Timmyyyyyyyyyyyyyyyyyyyyyyyyyy! with 26 'y' characters.
# Allow the CD to finish copying to the hard drive.
# Go to Settings -> System Information. The Xbox Dashboard credits will be displayed.

=== Parental Control Bypass ===

If Parental Control is enabled and the password set has been forgotten, all is not lost. Use the following sequence:
* {{input-x}} {{input-y}} {{input-lt}} {{input-x}}
SET PASS CODE, MOVIES and GAMES level can now be modified and the pass code removed if so desired.

With SET PASS CODE selected, press {{input-a}} or {{input-start}} to change the current pass code and once more to be prompted, "Do you wish to delete the current pass code?". Select Yes or No then {{input-a}}.

=== Format Admin Codes ===

Secret Xbox format codes to format all drives except C. The code is different for all versions of the Xbox. If you find your code, please post it here along with your xbox version (at least the last 2 digits of the serial number - the factory code where it was manufactured).

==== Different codes based on serial-number ====

MS support techs under certain conditions would ask for your serial number and verify registration of your Xbox before giving you a code to clear/format your fouled Xbox's HDD.{{FIXME|reason=What part(s) of the serial number they used to determine the correct code is unknown?}}

==== List of Xbox Format Admin Codes ====

All of these codes are entered at the MS Dashboard's "System Info" screen. (UNTESTED here, codes posted as given at original source site.)

* Xbox v1.0: {{input-y}} {{input-x}} {{input-ly+}} {{input-lx-}} {{input-a}}

Xbox 360 Backward Compatibility is Microsofts original Xbox emulator for the Xbox 360.

The emulator binary is called xefu.xex. The first resource is xb1krnl which is a modified version of [[Kernel|xboxkrnl.exe]].

=== Modifications to xboxkrnl.exe ===

The IDEXPRDT section has been dropped, additionally the extra data from the MS-DOS header is gone.
