Technical notes

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. ref: app/build.gradle.kts:66-70, app/build.gradle.kts:97, app/src/main/AndroidManifest.xml:90-104, app/src/main/cpp/ARM_ANDROID/CMakeLists.txt:78-82, app/src/main/cpp/ARM_ANDROID/CMakeLists.txt:359-360

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. ref: app/src/main/cpp/ARM_ANDROID/CMakeLists.txt:259-272, app/src/main/cpp/ARM_ANDROID/CMakeLists.txt:59-60, app/src/main/cpp/pcsx2/pcsx2/CMakeLists.txt:706, app/src/main/cpp/pcsx2/pcsx2/CMakeLists.txt:723-734

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. ref: app/src/main/java/com/sbro/emucorex/core/NativeApp.kt:30, app/src/main/java/com/sbro/emucorex/core/NativeApp.kt:430-432, app/src/main/java/com/sbro/emucorex/core/NativeApp.kt:563-570, app/src/main/java/com/sbro/emucorex/core/NativeApp.kt:587-619, app/src/main/cpp/ARM_ANDROID/src/runtime/upstream_vm_bridge.cpp:261-265, app/src/main/java/com/sbro/emucorex/core/EmulatorBridge.kt:612-618

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. ref: app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:16-17, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:80-217, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:150-151 (COH-H region), app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:176-190 (serial description), app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:278-314, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:337-391, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:365-367 (ROM window cleared), app/src/main/cpp/pcsx2/pcsx2/VMManager.cpp:1898-1912

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/java/com/sbro/emucorex/core/BiosValidator.kt:177-185, 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. ref: app/src/main/java/com/sbro/emucorex/core/DocumentPathResolver.kt:26-28, app/src/main/java/com/sbro/emucorex/core/DocumentPathResolver.kt:104-157, app/src/main/java/com/sbro/emucorex/core/DocumentPathResolver.kt:430-452, app/src/main/java/com/sbro/emucorex/core/DocumentPathResolver.kt:497-502, app/src/main/java/com/sbro/emucorex/core/DocumentPathResolver.kt:556-563

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. ref: app/src/main/cpp/pcsx2/pcsx2/ImGui/ImGuiManager.cpp:131-146, app/src/main/cpp/pcsx2/pcsx2/ImGui/ImGuiManager.cpp:148-152, app/src/main/cpp/pcsx2/pcsx2/ImGui/ImGuiManager.cpp:163, app/src/main/cpp/pcsx2/pcsx2/ImGui/ImGuiManager.cpp:224-229, app/src/main/cpp/pcsx2/pcsx2/ImGui/ImGuiManager.cpp:296-316, app/src/main/cpp/pcsx2/pcsx2/ImGui/ImGuiManager.cpp:483-536, app/src/main/cpp/ARM_ANDROID/src/runtime/upstream_vm_bridge.cpp:384-412, app/src/main/cpp/ARM_ANDROID/src/runtime/upstream_vm_bridge.cpp:437

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. ref: app/src/main/cpp/pcsx2/bin/resources/sounds/achievements/README.txt:1-3, app/src/main/cpp/ARM_ANDROID/src/integration/pcsx2_achievements_android.cpp:81-83, app/src/main/cpp/pcsx2/pcsx2/Config.h:1371-1374, app/src/main/cpp/pcsx2/pcsx2/Pcsx2Config.cpp:1963-1966

ps2-0230a-20080220.bin required in repo
PS2 BIOS image

  • Path: bios/ps2-0230a-20080220.bin
  • System: sony-playstation-2
  • Size: min 2.0 MB, max 8.0 MB
  • Validation: size
  • Source: app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:16-17, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:80-217, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:278-314, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:337-391
  • Platforms: batocera, emudeck, lakka, recalbox, retroarch, retrobat, retrodeck, retropie, rocknix, romm
  • Any image whose romdir holds RESET and ROMVER is accepted, whatever its name. The 2 to 8 MB range gates the folder scan; an image named in the configuration skips that range. Read into the 4 MB ROM region, which is zero-filled first, and truncated to it. Shorter than 2465792 bytes disables the OSDSys parameter HLE.

r27v1602f.7d optional in repo
Namco System 246 COH-H BIOS chip dump

  • Path: bios/r27v1602f.7d
  • System: sony-playstation-2
  • Size: 2.0 MB
  • SHA1: f0a74bbcaf80...
  • MD5: 52cca0058626...
  • CRC32: 2b2e41a2

  • Platforms: retrobat
  • 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.

r27v1602f.8g optional in repo
Namco System 256 COH-H BIOS chip dump

  • Path: bios/r27v1602f.8g
  • System: sony-playstation-2
  • Size: 2.0 MB
  • SHA1: bc4fb4e1e53a...
  • MD5: a58676c6bd79...
  • CRC32: b2a8eeb6
  • Source: app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:16-17, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:150-151, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:176-190, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:365-367, app/src/main/cpp/pcsx2/pcsx2/VMManager.cpp:1590-1598, app/src/main/java/com/sbro/emucorex/core/BiosValidator.kt:13-21
  • Platforms: retrobat
  • The System 256 counterpart, taken by the same path and the same widened size gate. A System 256 or Super 256 arcade manifest selects this name from the BIOS folder. Byte-identical to the r27v1602f.8g member of the MAME sys256 set.

ps2-0230a-20080220.rom1 optional in repo
DVD player ROM

  • Path: bios/ps2-0230a-20080220.rom1
  • System: sony-playstation-2
  • Size: max 4.0 MB
  • Source: app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:234-261, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:388, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:393-403, app/src/main/java/com/sbro/emucorex/core/DocumentPathResolver.kt:26-28, app/src/main/java/com/sbro/emucorex/core/DocumentPathResolver.kt:497-502
  • Tried as {bios}.rom1 then {biosbase}.rom1, with a case-insensitive retry on the open. Copied to the ROM1 region and truncated to 4 MB. Logged and skipped when absent. The storage access framework import does not carry this extension, so it is reachable only from a plain BIOS folder path.

ps2-0230a-20080220.rom2 optional in repo
Chinese ROM extension

  • Path: bios/ps2-0230a-20080220.rom2
  • System: sony-playstation-2
  • Size: max 4.0 MB
  • Aliases: SCPH-90006_BIOS_VX_HK _230.ROM2
  • Source: app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:234-261, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:389, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:393-403
  • Same two-step naming as rom1, copied to the ROM2 region. Present on Chinese region consoles. Carried by the same import restriction as rom1.

ps2-0230a-20080220.nvm optional in repo HLE fallback
Console NVRAM

  • Path: bios/ps2-0230a-20080220.nvm
  • System: sony-playstation-2
  • Size: 1.0 KB
  • Source: app/src/main/cpp/pcsx2/pcsx2/CDVD/CDVD.cpp:47-48, app/src/main/cpp/pcsx2/pcsx2/CDVD/CDVD.cpp:139-162, app/src/main/cpp/pcsx2/pcsx2/CDVD/CDVD.cpp:164-167, app/src/main/cpp/pcsx2/pcsx2/CDVD/CDVD.cpp:169-193
  • Read at the BIOS path with the extension replaced by nvm, case-insensitively. Carries the console id, the iLink id, the model number and the OSD configuration. A 1024 byte image is built in memory when the file is absent, short, or carries a blank config block, filled with a fixed iLink id and the language and region defaults of the detected BIOS region. Under a COH-H BIOS the blank-block test is skipped and the built image is 0xFF-filled with the iLink id alone.

ps2-0230a-20080220.mec optional in repo HLE fallback
Mechacon version

  • Path: bios/ps2-0230a-20080220.mec
  • System: sony-playstation-2
  • Size: 4 B
  • Source: app/src/main/cpp/pcsx2/pcsx2/CDVD/CDVD.cpp:50-51, app/src/main/cpp/pcsx2/pcsx2/CDVD/CDVD.cpp:195-208
  • Read at the BIOS path with the extension replaced by mec. Defaults to 0x00020603, or 0x0104020a under a COH-H BIOS, and is written back at that path when it cannot be read.

eeprom.dat optional in repo HLE fallback
DEV9 EEPROM

  • System: sony-playstation-2
  • Size: 64 B
  • Source: app/src/main/cpp/pcsx2/pcsx2/DEV9/DEV9.cpp:104-167
  • Opened from the working directory when the network adapter starts and mapped over 64 bytes. A compiled-in image stands in when the file is missing or cannot be mapped.

flash.dat optional missing HLE fallback
DEV9 SmartMedia flash image

  • System: sony-playstation-2
  • Size: max 8.2 MB
  • Source: app/src/main/cpp/pcsx2/pcsx2/DEV9/flash.cpp:9-16, app/src/main/cpp/pcsx2/pcsx2/DEV9/flash.cpp:62-86
  • Opened from the working directory at network adapter init and read as 1024 blocks of 16 pages of 512 bytes plus 16 ECC bytes. The card is filled with 0xFF when the file is absent.

<module>.irx optional unsourceable
IOP module injected at boot

  • System: sony-playstation-2
  • Source: app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:263-276, app/src/main/cpp/pcsx2/pcsx2/ps2/BiosTools.cpp:406-407, app/src/main/cpp/pcsx2/pcsx2/R3000AInterpreter.cpp:220, app/src/main/cpp/pcsx2/pcsx2/arm64/iop/iR3000A-arm64.cpp:1695, app/src/main/cpp/pcsx2/pcsx2/VMManager.cpp:1846, app/src/main/cpp/ARM_ANDROID/src/runtime/upstream_vm_bridge.cpp:462-467
  • Config key: EmuCore/CurrentIRX
  • Read into the ROM region at 0x3C0000 when the IOP program counter reaches 0x1630 and the setting is longer than three characters. The launcher fills it from the boot parameters when the picked file is an IRX. Empty otherwise.

GameIndex.yaml optional in repo game_data bundled
per-title compatibility and fix database

  • Path: resources/GameIndex.yaml
  • System: sony-playstation-2
  • Size: 2.6 MB
  • SHA1: 2d9878fdd709...
  • Source: app/src/main/cpp/pcsx2/pcsx2/GameDatabase.cpp:39, app/src/main/cpp/pcsx2/pcsx2/GameDatabase.cpp:1036-1037, app/src/main/java/com/sbro/emucorex/ui/gamedb/GameDbCatalogRepository.kt:97, app/src/main/java/com/sbro/emucorex/ui/gamedb/GameDbCatalogRepository.kt:202
  • Opened from the resources directory and parsed into the game database that drives per-title rounding modes, clamp modes, GS hacks and memory card filters. The Kotlin catalog reads the same file straight out of the package for the compatibility badges it draws.

RedumpDatabase.yaml optional in repo game_data bundled
disc hash database

  • Path: resources/RedumpDatabase.yaml
  • System: sony-playstation-2
  • Size: 1.8 MB
  • SHA1: dceb4536fba7...
  • Source: app/src/main/cpp/pcsx2/pcsx2/GameDatabase.cpp:1141, app/src/main/cpp/pcsx2/pcsx2/GameDatabase.cpp:1198-1199
  • Opened from the resources directory and parsed into the hash database used to name a disc from its dump.

patches.zip optional in repo game_data bundled
built-in game patch archive

  • Path: resources/patches.zip
  • System: sony-playstation-2
  • Size: 2.0 MB
  • SHA1: a3d939af27fe...
  • Source: app/src/main/cpp/pcsx2/pcsx2/Patch.cpp:118, app/src/main/cpp/pcsx2/pcsx2/Patch.cpp:290-317, app/src/main/java/com/sbro/emucorex/core/NativeApp.kt:432-433, app/src/main/java/com/sbro/emucorex/core/NativeApp.kt:621-635
  • Opened read only from the resources directory as a zip source and searched for the pnach matching the running serial and CRC. A failure to open is reported once and the built-in patches are dropped for the session. The app logs an error at startup when the copied archive is missing or holds no pnach.

Roboto-Regular.ttf optional in repo bundled
core text font

  • Path: resources/fonts/Roboto-Regular.ttf
  • System: sony-playstation-2
  • Source: app/src/main/cpp/ARM_ANDROID/src/runtime/upstream_vm_bridge.cpp:384-392, app/src/main/cpp/ARM_ANDROID/src/runtime/upstream_vm_bridge.cpp:402-411, app/src/main/cpp/ARM_ANDROID/src/runtime/upstream_vm_bridge.cpp:437
  • Read by the adapter's own font setup before the VM starts and handed to the core as the standard font. An empty font list is logged as a setup failure.

Twemoji.Mozilla.ttf optional in repo bundled
core emoji font

  • Path: resources/fonts/Twemoji.Mozilla.ttf
  • System: sony-playstation-2
  • Source: app/src/main/cpp/ARM_ANDROID/src/runtime/upstream_vm_bridge.cpp:393-400, app/src/main/cpp/ARM_ANDROID/src/runtime/upstream_vm_bridge.cpp:402-411
  • Read by the same font setup and appended as the emoji face. Skipped when the file cannot be read.

tfx.glsl required in repo bundled
Vulkan texture and framebuffer shader

  • Read from the resources directory when the Vulkan device is created. A read failure is reported and device creation fails.

convert.glsl required in repo bundled
Vulkan format conversion shader

  • Path: resources/shaders/vulkan/convert.glsl
  • System: sony-playstation-2
  • Source: app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Vulkan/GSDeviceVK.cpp:4901-4905, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Vulkan/GSDeviceVK.cpp:5247-5251
  • Read when the conversion pipelines are compiled and again as the vertex stage of the FXAA pipeline.

  • System: sony-playstation-2
  • Source: app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/OpenGL/GSDeviceOGL.cpp:767-768, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/OpenGL/GSDeviceOGL.cpp:2868-2872

cas.glsl optional in repo bundled
OpenGL contrast adaptive sharpening shader

  • Path: resources/shaders/opengl/cas.glsl
  • System: sony-playstation-2
  • Source: app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/OpenGL/GSDeviceOGL.cpp:771, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/OpenGL/GSDeviceOGL.cpp:3068-3088, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Common/GSDevice.cpp:1194-1205
  • Read as a compute program with the two include lines substituted, and tried only on an ES 3.2 context or on GL 4.2 with compute shaders. A failure turns CAS sharpening off.

imgui.glsl required in repo bundled
OpenGL overlay shader

  • Path: resources/shaders/opengl/imgui.glsl
  • System: sony-playstation-2
  • Source: app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/OpenGL/GSDeviceOGL.cpp:3152-3156

fxaa.fx required in repo bundled
antialiasing shader shared by both renderers

  • Path: resources/shaders/common/fxaa.fx
  • System: sony-playstation-2
  • Source: app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Vulkan/GSDeviceVK.cpp:2556-2561, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Vulkan/GSDeviceVK.cpp:5254-5258, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/OpenGL/GSDeviceOGL.cpp:767-768, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/OpenGL/GSDeviceOGL.cpp:2611-2619
  • Read as the fragment stage of the FXAA pipeline on Vulkan, inside the post-processing pipelines the device creation chain requires, so a missing file stops device creation there. On OpenGL the program is compiled beside the shadeboost one in the device creation chain, which returns on a read failure.

ffx_a.h required in repo bundled
CAS support header

  • Path: resources/shaders/common/ffx_a.h
  • System: sony-playstation-2
  • Source: app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Common/GSDevice.cpp:1194-1205, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Vulkan/GSDeviceVK.cpp:2569-2570, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/OpenGL/GSDeviceOGL.cpp:771
  • Read from the resources directory and pasted over the matching include line of the CAS shader, the compilers having no include support. It shares the fate of the CAS shader it is pasted into: fatal to device creation on Vulkan, and only the sharpening feature on OpenGL.

ffx_cas.h required in repo bundled
CAS kernel header

  • Path: resources/shaders/common/ffx_cas.h
  • System: sony-playstation-2
  • Source: app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Common/GSDevice.cpp:1194-1205, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Vulkan/GSDeviceVK.cpp:2569-2570, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/OpenGL/GSDeviceOGL.cpp:771
  • Read and substituted the same way as the other CAS header, with the same consequence per renderer when it is missing.

message.wav optional in repo
achievement notification sound

  • Path: resources/sounds/achievements/message.wav
  • System: sony-playstation-2
  • Source: app/src/main/cpp/ARM_ANDROID/src/integration/pcsx2_achievements_android.cpp:81, app/src/main/cpp/ARM_ANDROID/src/integration/pcsx2_achievements_android.cpp:1245-1250, app/src/main/cpp/pcsx2/pcsx2/Pcsx2Config.cpp:1963-1966, app/src/main/java/com/sbro/emucorex/core/NativeApp.kt:461-467
  • Played from the resources directory whenever an achievement notification is raised and no custom sound is configured. Sound effects and the notification sound both default on. The vendored tree carries only the README for this directory, so the file has to be supplied; the Android sound callback returns without playing when the path is not a file. Upstream v2.8.0 ships it at 15696 bytes.

unlock.wav optional in repo
achievement unlock sound

  • Path: resources/sounds/achievements/unlock.wav
  • System: sony-playstation-2
  • Size: 198.0 KB
  • SHA1: da328a0a3074...
  • Source: app/src/main/cpp/ARM_ANDROID/src/integration/pcsx2_achievements_android.cpp:82, app/src/main/cpp/ARM_ANDROID/src/integration/pcsx2_achievements_android.cpp:1313-1318
  • Played on an unlock under the same two settings, both on by default. Absent from the vendored tree. Upstream v2.8.0 ships it at 202702 bytes.

lbsubmit.wav optional in repo
leaderboard submission sound

  • Path: resources/sounds/achievements/lbsubmit.wav
  • System: sony-playstation-2
  • Source: app/src/main/cpp/ARM_ANDROID/src/integration/pcsx2_achievements_android.cpp:83, app/src/main/cpp/ARM_ANDROID/src/integration/pcsx2_achievements_android.cpp:1458-1463
  • Played on a leaderboard submission under the same two settings, both on by default. Absent from the vendored tree. Upstream v2.8.0 ships it at 82096 bytes.

games.db optional in repo game_data bundled
bundled catalog of PS2 titles

  • System: sony-playstation-2
  • Source: app/src/main/java/com/sbro/emucorex/data/ps2/Ps2CatalogRepository.kt:17-18, app/src/main/java/com/sbro/emucorex/data/ps2/Ps2CatalogRepository.kt:27, app/src/main/java/com/sbro/emucorex/data/ps2/Ps2CatalogRepository.kt:39-56
  • SQLite catalog carried in the package assets and copied into internal storage the first time the catalog is queried, then read from there. A copy already present is kept.

<SERIAL>_<CRC>.pnach optional unsourceable game_data
per-title cheat file

  • Path: cheats/<SERIAL>_<CRC>.pnach
  • System: sony-playstation-2
  • Source: app/src/main/cpp/pcsx2/pcsx2/Patch.cpp:332-345, app/src/main/cpp/pcsx2/pcsx2/Patch.cpp:347-369, app/src/main/java/com/sbro/emucorex/ui/cheats/CheatManagerScreen.kt:291-309, app/src/main/java/com/sbro/emucorex/data/CheatRepository.kt:186-220, app/src/main/java/com/sbro/emucorex/data/CheatRepository.kt:304-311
  • The cheats folder is searched for the running serial and CRC, then for files carrying the CRC alone, both with a trailing wildcard so a suffix after the 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.

<hash>.png optional unsourceable game_data
replacement texture

  • Path: textures/<SERIAL>/replacements/<hash>.png
  • System: sony-playstation-2
  • Source: app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/HW/GSTextureReplacements.cpp:36-42, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/HW/GSTextureReplacements.cpp:328-331, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/HW/GSTextureReplacements.cpp:442-500
  • Read when texture replacement is on. The replacements folder under the running serial is walked recursively and a file counts only when its name parses as the TEX0 hash, optional CLUT hash, optional region size and format that the texture cache looks it up by. A directory whose case does not match is reported.

<driver>.zip optional unsourceable
replacement Vulkan driver package

  • System: sony-playstation-2
  • Source: app/src/main/java/com/sbro/emucorex/core/GpuDriverCatalogRepository.kt:143-147, app/src/main/java/com/sbro/emucorex/core/GpuDriverCatalogRepository.kt:76-87, app/src/main/java/com/sbro/emucorex/core/GpuDriverManager.kt:98-170, app/src/main/java/com/sbro/emucorex/core/GpuDriverManager.kt:172-181, app/src/main/java/com/sbro/emucorex/core/GpuDriverManager.kt:214-228, app/src/main/cpp/ARM_ANDROID/src/runtime/android_runtime.cpp:138-152, app/src/main/cpp/ARM_ANDROID/src/runtime/android_runtime.cpp:401-402, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Vulkan/VKLoader.cpp:136, app/src/main/cpp/pcsx2/pcsx2/GS/Renderers/Vulkan/VKLoader.cpp:200-206
  • Listed by a catalog fetched from the EmuCoreV-Drivers repository, or picked from the device. A catalog download whose length differs from the size the 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.
