One run of profile_sync --all --rebase-refs --fresh. Every guard held: no ref to review, no prose left under an older pin, no file name or hash literal gained in a cited file since the pin, no built_by pin and no pin keyed by build mode. The site's record of cited source paths is rebuilt with them.

Emulator for Sunplus SPMP8000 NGame1.0 games written in Rust by
|
|
AloysHF. The libretro core and the spmp8000-emu standalone binary share
|
|
the spmp8000emu-core crate. A .bin game is read from its full path
|
|
(need_fullpath = true, crates/spmp8000emu-libretro/src/libretro/api.rs:96,
|
|
from_path_with_config, crates/spmp8000emu-core/src/emulator.rs:63-68),
|
|
its header parsed, the payload DES-decrypted and LZ77/RLE-decompressed
|
|
with keys and tables compiled into the core, then loaded at the code
|
|
address. The system API (emuIf, NativeGE, eCos) is implemented in Rust
|
|
(crates/spmp8000emu-core/src/api/).
|
|
|
|
Guest file calls (emuIfFsFileOpen, NativeGE_fsOpen, NativeGE_readRecord,
|
|
NativeGE_writeRecord) resolve the guest path under the directory of the
|
|
loaded .bin (crates/spmp8000emu-core/src/emulator.rs:129-131,
|
|
crates/spmp8000emu-core/src/api/mod.rs:125-127,
|
|
crates/spmp8000emu-core/src/api/emu_fs.rs:9-13). What a game reads or
|
|
writes there is its own data and saves.
|
|
RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY and GET_SAVE_DIRECTORY are
|
|
defined (crates/spmp8000emu-libretro/src/libretro/constants.rs:36,
|
|
crates/spmp8000emu-libretro/src/libretro/constants.rs:47) but nothing
|
|
calls them.
|
|
|
|
MIDI resources are rendered by a sample-based synthesiser whose tone
|
|
bank is the SPMP8000 firmware's own PCM tone library, compiled into the
|
|
core with include_bytes! (crates/spmp8000emu-core/src/tone_library.rs:8,
|
|
crates/spmp8000emu-core/src/audio_resource.rs:498-499). It is the only
|
|
embedded data and the only firmware-derived component, and nothing is read
|
|
from disk for it.

note: >-
|

Compiled into the core from crates/spmp8000emu-core/assets/tonelib.bin
|
|
and never opened at run time. 256-entry patch table (128 melodic,
|
|
128 percussion) followed by per-zone PCM samples, read by the
|
|
NativeGE MIDI path. Hashes are of the file in the emulator
|
|
repository, which states the SHA-256.
