In Xemu, go to System > Audio Settings . Reduce the sample rate from 48kHz to 44.1kHz or enable "Audio Latency: High". 3.4. Memory Address 0x4627 Corruption A specific memory address (0x4627) stores the thermal status of the MCPX. If a game or BIOS write operation accidentally modifies this address (a known issue in some homebrew Xbox titles), the value flips to "critical hot."
