Standard Redump ISOs are not compatible and must be converted. | | Linux (Flatpak) won't load the HDD | Flatpak sandbox permissions block access. | Use Flatseal to grant xemu access to the folder containing your xbox_hdd.qcow2 file, or move the HDD image to the allowed directory: $HOME/.var/app/app.xemu.xemu/data/xemu/xemu/ . | | The EEPROM region mismatch | Wrong region for the loaded game. | Use the XboxEepromEditor tool to modify your eeprom.bin file to match the region of your game disc (NTSC, PAL, etc.). |
