PlayStation 2 emulator for Android, package com.sbro.emucorex, arm64-v8a only,
minSdk 29. A Kotlin and Compose front end drives a PCSX2 tree vendored under
app/src/main/cpp/pcsx2 and pinned to v2.8.0, reached through the ARM_ANDROID
adapter that owns the JNI entry points. Frontends start the exported activity
com.sbro.emucorex.MainActivity; ES-DE passes the disc as the intent data URI.

The whole upstream core is linked, with three files swapped out of the target:
Achievements.cpp, Host/SDLAudioStream.cpp and Input/SDLInputSource.cpp are
removed and replaced by the adapter's own achievements, AAudio and OpenSL, and
input sources. OpenGL and Vulkan are on, pcsx2-qt is never added, and the
DX11 and DX12 renderers sit in the Windows branch of the core CMakeLists.

Storage. The data root is the app files directory; the app creates cache,
resources, inis, sstates and memcards under it, then copies the whole resources
asset tree out of the package into resources. The core is handed AppRoot,
DataRoot, Resources, Settings and Cache from that root, and the launcher sets
Folders for Bios, Savestates, MemoryCards, Textures, Cheats, Patches and Logs
per run.

A BIOS image is required and boot stops without one: LoadBIOS returning false
makes VMManager report that a PlayStation 2 BIOS is needed. Only a GS dump
replay skips the load. Detection is by content: the folder scan keeps files
between 2 and 8 MB and accepts an image whose romdir carries a RESET entry
followed by a readable ROMVER, the fifth ROMVER character giving the zone among
Japan, USA, Europe, Asia, China, T10K, COH-H, Test and Free, with EXTINFO
supplying the serial. An image named in the configuration is opened at its own
path without the size filter. No hash is matched, and a console image is
matched under no name.
MIN_BIOS_SIZE was halved to 2 MB to admit the Namco System 246/256 chip dumps,
which are 2 MB where a console image is 4. Three other changes came with it:
a COH-H board is region 11 rather than 8, its description is built from the
EXTINFO serial because Sony left the version and date fields identical across
those BIOSes, and the ROM window is zero-filled before the read so the unused
upper half cannot retain the previous image.

An arcade launch starts from a manifest carrying an NM game id and a board
generation. It selects the board BIOS by name from the BIOS folder,
r27v1602f.8g for System 256 and Super 256 and r27v1602f.7d for System 246, and
keeps the configured BIOS with a warning when that file is absent. The dongle,
memory card, boot ELF, SRAM and media the manifest names are per-title content
resolved beside it.
ref: app/src/main/cpp/pcsx2/pcsx2/VMManager.cpp:1530-1598,
app/src/main/cpp/pcsx2/pcsx2/VMManager.cpp:1608-1733
The app runs its own gate before launching. A candidate is a .bin, .rom, .7d
or .8g between 512 KB and 8 MB. It passes when the core's IsBIOS accepts it,
reached through isBiosPath on the path or isBiosFd on /proc/self/fd, or when
its name carries scph, ps2, bios, rom or r27v1602f. The two extra extensions
are the board positions the Namco dumps carry instead of a conventional one.
ref: app/src/main/java/com/sbro/emucorex/core/BiosValidator.kt:13-21,
app/src/main/java/com/sbro/emucorex/core/BiosValidator.kt:112-146,

app/src/main/cpp/ARM_ANDROID/src/jni/native_app_jni.cpp:493-515
A BIOS folder picked through the storage access framework is copied flat into
imported-bios under the external files directory, and Folders/Bios points there.
The import filter takes any .bin, .rom, .7d or .8g, plus .mec, .nvm and .elf
whose name carries one of the hints. Neither rom1 nor rom2 is an accepted
extension, and LoadExtraRom looks for exactly {bios}.rom1 or {biosbase}.rom1,
so the two ROM modules only reach the core when Folders/Bios is a plain
filesystem path used as-is. A re-import preserves the .nvm and .mec sitting
beside the image.

Much of the bundled resource tree is compiled out on this platform and never
read. ImGuiManager::Initialize returns false before creating the ImGui context,
so LoadFontData and the three fonts it reads are unreachable, and SetFonts and
ReloadFonts both guard on that context. InitializeFullscreenUI returns false
unconditionally, so FullscreenUI::Initialize never runs and nothing under
fullscreenui or icons is loaded. The adapter reads two fonts of its own instead
and hands them over through SetFonts.

The three achievement sounds are the one resource the code reads that the tree
does not carry. Their directory holds only the README naming their origin,
while upstream v2.8.0 ships message.wav at 15696 bytes, lbsubmit.wav at 82096
and unlock.wav at 202702. All four sound settings default on, so a signed-in
session asks for them at every notification.

description: "Namco System 246 COH-H BIOS chip dump"
note: >-
Admitted since MIN_BIOS_SIZE fell to 2 MB. The board position is the
extension, so the picker takes .7d alongside .bin and .rom, and the name
hint r27v1602f carries it past the name test. Read into the 4 MB ROM
window, whose upper half is cleared first. ROMVER marks it T with a fifth
character Z, which is what makes it COH-H and region 11; its description
comes from the EXTINFO serial. A System 246 arcade manifest selects this
name from the BIOS folder. Byte-identical to the r27v1602f.7d member of the
MAME sys246 set.

pipelines unconditionally and returns on a failure, so a missing file stops

The cheats folder is searched for the running serial and CRC, then for files

CRC is kept. An arcade title, whose serial starts with NM and whose CRC is
zero, is matched on the serial alone. The patches folder is searched the
same way for patches rather than cheats. The app's cheat manager keeps a
picked pnach document in its own store and writes the enabled blocks into
the cheats folder as <SERIAL>_<CRC>.pnach, or <CRC>.pnach without a serial.

Listed by a catalog fetched from the EmuCoreV-Drivers repository, or picked

catalog states is discarded. The archive is unpacked into a directory named
after it under driver in internal storage, entries carrying a parent path
segment being refused, and the Vulkan library it holds is recorded in a
driver_name.txt written beside it. The install is removed when that library
does not start with the ELF magic or when its GPU vendor, taken from the
catalog or from markers in the library, does not match the device. The
renderer then resolves the driver through adrenotools from that pair. The
system loader is used when no driver is configured.

exclusion_note: >
Left out are the parts of the bundled resource tree that this platform compiles
out. ImGuiManager::Initialize returns false before the ImGui context exists, so
LoadFontData never runs and fonts/RobotoMono-Medium.ttf, fonts/fa-solid-900.ttf
and fonts/promptfont.otf are never read; InitializeFullscreenUI returns false
unconditionally, so FullscreenUI::Initialize never runs and nothing under
fullscreenui or icons is loaded, cover-placeholder.png included. The DX11 and
DX12 renderers sit in the Windows branch of the core CMakeLists, so
shaders/dx11 is dead here. game_controller_db.txt has one consumer,
Input/SDLInputSource.cpp, which the adapter removes from the target and replaces
with a source that never opens it. The user resource override folder is only
ever consulted by those same font and controller database reads, so it is dead
with them. Left out with these are the app's other package assets, which are
read through the asset manager and never reach the filesystem:
catalog/rom_identity_index.json, catalog/rom_identity_overrides.json and
catalog/pcsx2_compat_index.json. Left out too is what the emulator writes and
reads back, which is state rather than system files: the inis, the per-game
settings and input profiles, the memory cards, the save states, the snapshots,
the shader and texture caches, the logs, the dumped textures, and the
system-ca-bundle.pem the app exports from the Android trust store, and the
per-title arcade content a manifest names. The covers folder is inert: its
only readers are the FullscreenUI game list and GameList::DownloadCovers,
which only FullscreenUI calls, and the app runs its own cover cache.
