FAQ

Q: Can I get some help?

Of course, but first please read through the setup guide. If you still have questions, please read the following FAQs. If you're still having problems, head to #help in the xemu Discord server.

Chat Badge

Q: I think I've found a bug, what do I do?

Join the Discord server and chat about what you're seeing in #general, maybe it's a known issue. We can work together to get it recorded and fixed.

Q: Are there system requirements?

See here.

Q: What BIOS do I need to use?

Your MCPX and BIOS dump should be for a 1.0 Xbox. It's suggested that your MCPX dump be 1.0 and that a compatible BIOS image be used (users have reported success with "COMPLEX 4627").

Q: Do I need to have an EEPROM file?

A default one will be created if you do not provide one.

Q: Why am I getting The guest has not initialized the display

This is likely due to a mismatch of MCPX and BIOS images, or a corrupt MCPX boot ROM.

Q: Why am I getting Please insert an Xbox disc...? I already loaded an ISO.

Try restarting xemu. If you continue to get the message, your ISO may not be dumped in a compatible way. Try using extract-xiso to pack your ISO.

Q: Is there a game compatibility list?

Yes, visit https://xemu.app

Q: Does game x work?

Possibly. Check the compatibility list first if you're curious, or try it out for yourself. You are invited to submit a compatibility report too.

Q: Does xemu run my game's default.xbe?

No, not directly. xemu emulates the hardware of the system, so you'll need to have a disc image of your game backup. You can use extract-xiso or qwix to create an image.

Q: Does xemu support "redump" style ISOs?

No, not yet. You can however convert a redump style ISO to a compatible ISO. More info here.

Q: Why am I getting an Assertion failed! message?

When a game exercises a piece of code in xemu that has not yet been implemented or verified, xemu will assert which forces execution to stop. The reason for this is that anything happening beyond that point may be unpredictable and significantly increase the debugging burden.

Q: How do I enable widescreen mode?

You can change the setting in your dashboard or use the EEPROM editor to enable widescreen. Then select 'Scale (Widescreen 16:9)' in xemu View scaling mode. Note: not all games support widescreen.

Q: How can I increase the resolution?

For all titles the rendering resolution can be easily scaled by navigating to View→Rendering Scale. For titles that natively support higher resolutions, you can enable the associated mode in your dashboard or by using the EEPROM editor.

Q: Are there any plans for a mobile port of xemu?

There are currently no plans for a mobile port of xemu on iOS or Android, the emulator hasn't reached the performance necessary to run well on iOS or Android at this time.

Q: Can xemu load an Xbox game disc from my computer's DVD drive?

Generally, no. You will need to create a backup of your game disc. Please see here for more information about creating and using disc images.

Q: Why does xemu crash when I enable Surround Sound in my EEPROM?

This is because Surround Sound isn't implemented in xemu yet, please disable this in your EEPROM if you have it enabled.
