Upstream moved under 145 profiles: 679 refs shifted and 452 followed a renamed file, against 6,483 that still anchor where they were written. The recale rewrites the located ranges only, keeping the annotations and the sentences that carry them, and 106 pins advance in the same commit because refs and source_commit name one revision or the profile describes two at once. Nothing here was guessed. The 183 refs that are CHANGED, GONE or AMBIGUOUS are untouched, and the 57 profiles holding them keep their old pin until someone reads the diff: profile_sync refuses to recale a profile while any of its refs needs a re-read. trident kept its pin too, its annotated ref being one the writer will not rewrite.

Xemu is a free, open-source Xbox emulator based on QEMU.
|
|
Three firmware files are required for operation: MCPX boot ROM,
|
|
flash ROM (BIOS), and EEPROM image. A pre-built HDD image is
|
|
also needed. The EEPROM can be auto-generated by xemu if not
|
|
provided. Config stored in xemu.toml under sys.files section.

|
|
note: |
|
|
Overlaid on the last 512 bytes of the flash ROM region at boot.
|
|
Mapped to 0xFFFFFE00-0xFFFFFFFF. Disabled after early init
|
