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: |
|
|
Accuracy-focused GB/GBC emulator. No BIOS required for normal operation;
|
|
built-in HLE boot sequence skips the Nintendo logo animation.
|
|
|
|
Core option gambatte_gb_bootloader (default: enabled) enables loading
|
|
official boot ROMs from the system directory for the real startup animation.
|
|
If missing, emulation works without them.
|
|
|
|
Boot ROM selection by hardware mode:
|
|
- DMG: gb_bios.bin (256 bytes)
|
|
- CGB or GBA: gbc_bios.bin (2304 bytes)
|
|
|
|
In GBA mode the core patches the CGB boot ROM at 0xF2 to fake GBA
|
|
detection (ld b,0x01), enabling GBA-enhanced features in compatible
|
|
GBC games.
|
|
|
|
The upstream standalone supports SGB boot ROM loading; the libretro
|
|
port does not implement this.
|
|
|
|
Custom palette files (palettes/*.pal) are user-created colorization
|
|
configs loaded when GB Colorization is set to "custom". These are
|
|
user-generated content, not distributable files.
