Common Error Messages

"The guest has not initialized the display"

Back to the Top

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

---

"Please insert an Xbox disc"

Back to the Top

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.
