Profiles, the wiki, comments, docstrings, command output and schema descriptions carried em-dashes, clause-joining semicolons, unicode arrows, box-drawing banners and check-mark glyphs. Each sentence was rewritten rather than having its character swapped. Hashes, paths, source_ref values and every cited file:line are unchanged, which a comparison of each parsed profile against the previous revision confirms. validate_pr comments now say PASS and FAIL in words, and source_ref values in a profile's structured blocks render as code. test_prose_style fails if any of these comes back, in tracked files or in the generated site.

|
Virtual Boy emulator for Android, published as com.simongellis.vvb
|
|
(app/build.gradle:62,65-66) and reached by ES-DE through its
|
|
VIRTUAL-VIRTUAL-BOY find rule, which hands the game over as an ACTION_VIEW
|
|
intent on a content URI (MainActivity.kt:126-131, MainActivity.kt:40-45). The
|
|
hardware sits in a Rust library packaged as libvvb.so and loaded when the
|
|
application starts (VvbApplication.kt:69, Cargo.toml [lib]), and the Kotlin side
|
|
owns the menus, the input mapping and every file access. Display goes through
|
|
mono, anaglyph, stereo, Google Cardboard and Leia CNSDK renderers, each
|
|
carrying its GLSL as string constants in the Rust sources
|
|
(src/video/renderers/mono.rs:10-26, src/video/renderers/stereo.rs:13-29).
|
|
|
|
The console has no boot ROM and the emulator loads none. The memory map
|
|
declares Vram, Audio, Hardware, Dram, Sram and Rom, and load_game_pak takes
|
|
the cartridge image and its SRAM, leaving the Rom region unpopulated until a
|
|
game arrives (src/emulator/memory.rs:8-14, src/emulator/memory.rs:115,
|
|
src/emulator/memory.rs:134-149).
|
|
|
|
Games are read from .vb, .vboy and .bin, or from the first member of a zip
|
|
answering the same test (GamePakLoader.kt:20-27, GamePakLoader.kt:97-98). The
|
|
image has to be a power of two and at most 0x01000000 bytes, either test
|
|
aborting the load (GamePakLoader.kt:39-45, GamePakLoader.kt:57), and the core
|
|
applies the same two limits again when the image reaches it
|
|
(src/emulator/memory.rs:136-141). The MD5 of the image names the directory
|
|
that holds the save data, where the app writes .srm and
|
|
save_states/<slot>.sav as it runs (GamePakLoader.kt:30-32,
|
|
GamePak.kt:8-9,30, src/emulator/state.rs:30-38). Cardboard lens parameters
|
|
come from scanning the viewer QR code and are kept by the SDK, the app asking
|
|
for them and starting a scan when none are saved
|
|
(src/video/renderers/cardboard.rs:29-34).
|
|
|
|
One tree ships two flavours: playStore, and leia, which appends .leia to the
|
|
application id and renders through the CNSDK (app/build.gradle:92-100). Both
|
|
carry the same nine homebrew titles, stored uncompressed so they can be opened
|
|
by descriptor (app/build.gradle:117).
|
|
|
|
files:
|
|
# -- Bundled homebrew, assets/games, listed by res/raw/bundledgames.json --
|
|
# Each title is served over content://com.simongellis.vvb.assets and then read
|
|
# through the same path as a user game, so the power of two and 0x01000000
|
|
# tests apply to it. The id an entry declares is the MD5 of the image.
|
|
# Common refs: BundledGameRepository.kt:9-13, AssetsProvider.kt:18-19,
|
|
# GamePakLoader.kt:35-49.
