Profiles that read two repositories, a libretro port and its upstream, now prefix each citation with source or upstream, decided by which tree carries the cited value at its pin. The emulator pages use the word to tell libretro glue, emulator code as the port carries it, and the upstream emulator apart.

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.
