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.

Frozen snapshot of VBA-M circa 2011, optimized for libretro by Squarepusher.
|
|
|
|
Built-in HLE BIOS (myROM array, src/gba.c:8930) handles all standard SWI
|
|
calls. No external BIOS file needed for most games.
|
|
|
|
BIOS loading gated by HAVE_HLE_BIOS (build/Makefile.common:3) and core option
|
|
vbanext_bios (default: enabled). When enabled, retro_init resolves gba_bios.bin
|
|
in system_dir (libretro/libretro.c:213-218). CPUInit loads via utilLoad(),
|
|
validates size == 0x4000, sets useBios = true (src/gba.c:12943-12950). On
|
|
failure, myROM is memcpy'd as HLE fallback (src/gba.c:12954-12956).
|
|
|
|
With real BIOS, execution starts at 0x00000000 (BIOS entry point). Without,
|
|
jumps to 0x08000000 (ROM entry), skipping boot animation
|
|
(src/gba.c:13134-13151).
|
|
|
|
Upstream VBA-M CPUInit (src/core/gba/gba.cpp:5137-5165) is functionally
|
|
identical. No divergences in BIOS handling.
