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.

notes:
|
|
altirra_note: >
|
|
The Altirra OS/BASIC replacements are open-source alternatives compiled
|
|
directly into the core binary (roms/ directory in source). They provide
|
|
good compatibility for most software but real ROMs give better accuracy.
|
|
cfg_note: >
|
|
On first boot the core creates .atari800.cfg in the frontend home directory.
|
|
It scans the system directory for ROM files by CRC32 first, then by filename.
|
|
The core option atari800_opt1 controls whether this legacy config is loaded.
|
|
machine_selection: >
|
|
Core option atari800_system selects the emulated machine. Each machine type
|
|
has its own preferred OS ROM auto-select order defined in sysrom.c.
