gopher2600 and gearsystem cited a blank line one past the fingerprint comparison and the SG-1000 bootrom guard. fuse cited a glob, which resolves against nothing: the two machines it means are named now. gsplus, gopher64 and geolith carried refs from a newer tree than their pin.

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;
|
|
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:212-232; src/savestates.rs:179,236). 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:583-593,600-615,630; src/lib.rs:141-147).
|
|
portable.txt is tested for existence only, to move those three directories
|
|
beside the executable (src/ui.rs:186-200).
|
|
|
|
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:688-690), the RobotoMono face handed to SDL_ttf from memory
|
|
(src/ui/video.rs:109, 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:4-5,619) and the Slint translations bundled at
|
|
build time (build.rs:11).
