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.

Nintendo 64 emulator written in Rust by Logan McNaughton, with parallel-rdp
|
|
driving the RDP and rcheevos providing RetroAchievements. Portions of the
|
|
emulation are adapted from mupen64plus and ares. ES-DE and RetroBat both run
|
|
the release binary, RetroBat in portable mode.
|
|
|
|
The boot chain reads no file. Both PIF ROMs are compiled in as 1984 byte
|
|
arrays, the size of the PIF ROM window (src/device/pif/rom.rs:1,90 and
|
|
src/device/pif.rs:7). reset_pif installs the PAL image when the cartridge
|
|
country code is one of DFIPSUXY and the NTSC image otherwise
|
|
(src/device/pif.rs:252-257, src/device/cart/rom.rs:137-143), and the VR4300
|
|
runs IPL1 and IPL2 out of that array: reads below the PIF RAM offset are
|
|
served from it and writes there panic (src/device/pif.rs:31-58). The CIC needs
|
|
no file either. set_cic hashes the cartridge IPL3 region with SHA-256 and maps
|
|
the six known digests to a seed byte, with the 6102 seed as the fallback
|
|
(src/device/cart/rom.rs:147-175).
|
|
|
|
64DD is not emulated, so no IPL image is involved.
|
|
|
|
A Transfer Pak port reads two files whose paths come from the configuration,
|
|
gb_rom_path and gb_ram_path, and attaches them when both are set
|
|
(src/lib.rs:194-200). The pair is a Game Boy cartridge and its save, supplied
|
|
by the player: the loader takes the ROM as is and only inspects the tail of
|
|
the RAM for MBC3 clock state (src/device/controller/gbcart.rs:37-75), then
|
|
writes the RAM back on shutdown (src/lib.rs:276-288). The code fixes no name,
|
|
size or hash for either, so neither carries a file entry here.
|
|
|
|
The SC64 SD card image is created rather than obtained: an empty save is
|
|
resized to 64 MB and FAT formatted on first access
|
|
(src/device/cart/sc64.rs:4,34-38). Cartridges come from argv, plain or as the
|
|
first matching entry of a zip or 7z archive (src/device.rs:188-256).
|
|
|
|
Everything else under the configuration, data and cache directories is written
|
|
by the emulator: config.json and cheats.json (src/ui/config.rs:99-111,134-146),
|
|
retroachievements.json (src/lib.rs:209, src/retroachievements.rs:37,61),
|
|
ice_config.json from the netplay server response (src/ui/netplay.rs:715-718,
|
|
src/netplay.rs:419), the eeprom, sram, flash, mempak, sdcard and romsave saves
|
|
and the savestates (src/ui/storage.rs:213-233, src/savestates.rs:201,260). For
|
|
a netplay launch the GUI serialises the cheats to the cache directory, passes
|
|
them to a re-exec of itself through the hidden --cheats flag and deletes the
|
|
file afterwards (src/ui/gui.rs:590-600,607-622,637, src/lib.rs:141-147).
|
|
portable.txt is tested for existence only, to move those three directories
|
|
beside the executable (src/ui.rs:216-230).
|
|
|
|
Compiled-in data: the cheat database (src/cheats.rs:31), the No-Intro
|
|
Nintendo 64 export that names entries in the ROM browser
|
|
(src/ui/gui.rs:695-697), the RobotoMono face handed to SDL_ttf from memory
|
|
(src/ui/video.rs:132, src/ui/input_profile.rs:99), the parallel-rdp SPIR-V
|
|
modules (parallel-rdp/spirv.hpp and parallel-rdp/spirv_crt.hpp, used at
|
|
parallel-rdp/interface.cpp:4-5,638) and the Slint translations bundled at
|
|
build time (build.rs:11).
