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: |
|
|
Fork of higan v094 by Alcaro. Restores HLE for coprocessor chips removed
|
|
in v094, adds firmware_appended support and SuperFX overclocking.
|
|
Three profiles: accuracy, balanced, performance (PPU differs, not firmware).
|
|
Core option bsnes_chip_hle (default LLE, requires bsnes_violate_accuracy)
|
|
controls HLE/LLE at runtime. ref: target-libretro/libretro.cpp:428-442
|
|
|
|
Firmware loaded from system_dir via file::exists + mmapstream.
|
|
No hash or size validation on any firmware file.
|
|
ref: target-libretro/libretro.cpp:242-264
|
|
|
|
firmware_appended: firmware can be appended to end of ROM file.

ref: ananke/heuristics/super-famicom.hpp:83

Upstream higan v094 by byuu (2014, site defunct). Mercury preserves v094
