Nothing that\nthe standalone distribution carries next to the executable (resources/,\ngameProfiles/default/) comes with the core. The community graphic packs,\nwhich standalone downloads, are compiled into it.\nref: CMakeLists.txt:4-7, src/CMakeLists.txt:75-90,\n .gitlab-ci.yml:123, 129, 152, 414, 435, 440, 448, 478, 564, 583\n\nPath model. Cemu resolves every file through four roots: the user data\npath (keys.txt, otp.bin, seeprom.bin, cafeLibs/, graphicPacks/,\nshareddata.bin, resources/miiverse/, the default mlc01), the config path\n(settings.xml, network_services.xml, controllerProfiles/, per-title\ngameProfiles/), the data path (resources/sharedFonts/, gameProfiles/default/)\nand the MLC. The libretro core points user data, config, cache and data at\n/Cemu, and always puts the MLC at /Cemu/mlc01: it\ndoes not read settings.xml. The Cemu\nsubdirectory is not doubled when the frontend already hands over a\ndirectory of that name (saves sorted per core). Standalone Cemu uses the\nportable directory next to the executable when it exists, otherwise the\nuser data directory given per system in data_root, and the MLC defaults to\n/mlc01. path: entries below are\nthe libretro destination under the system directory, or under the save\ndirectory for the MLC (load_from), and standalone_path: is relative to the\nCemu user data directory, which holds the MLC by default (load_from\ndata_dir). The core reports library_name \"Cemu\"\n(src/libretro/CemuLibretro.cpp:4173).\nref: src/libretro/CemuLibretro.cpp:2110-2170,\n src/libretro/CemuLibretro.cpp:4083-4091,\n src/gui/wxgui/CemuApp.cpp:90-123, src/gui/wxgui/CemuApp.cpp:127-171,\n src/config/ActiveSettings.cpp:295-321\n\nkeys.txt is read once from the user data path. A missing file is created\nwith a comment header and an example key. Each line is stripped of\ncomments, spaces, dashes and underscores and must then be 32 hex\ncharacters, otherwise an error is raised for that line. FindDiscKey tries\nevery key in order against the encrypted partition header of a .wud/.wux\nand falls back to a 16-byte .key next to the image. The libretro\ncore asks that question before setting up any renderer and refuses the\nload with a message naming keys.txt when no key matches, so an encrypted\ndisc image does not start without it. .wua archives, .rpx and NUS\ndirectories are not encrypted with a disc key and load without the file.\nref: src/Cafe/Filesystem/FST/KeyCache.cpp:65-137,\n src/Cafe/Filesystem/FST/FST.cpp:192-246,\n src/libretro/CemuLibretro.cpp:6094-6142\n\nShared fonts. LoadSharedData runs at every title start and looks for the\nfour fonts of title 0005001b-10042400 in the MLC first, then under\nresources/sharedFonts/ of the data path. All four must be found in one\nplace or the other, otherwise none is loaded and the code tries\nshareddata.bin, a 32 MiB dump of the shared data region, read from the\nuser data path straight into 0xF8000000. With nothing loaded a title that\ncalls OSGetSharedData receives the placeholder font compiled into the\nbinary, decompressed from a zlib array, so games run but with one Latin\nface standing in for the CJK sets. The four files in resources/sharedFonts/\nof the source tree are Noto Sans CJK Medium faces under the console names,\nnot dumps: the standalone distribution ships them, the libretro core does\nnot and looks under /Cemu/resources/sharedFonts/.\nref: src/Cafe/CafeSystem.cpp:286-365, src/Cafe/CafeSystem.cpp:907-911,\n src/Cafe/OS/libs/coreinit/coreinit.cpp:137-184,\n src/resource/CafeDefaultFont.cpp:2562-2569\n\nOnline files. iosuCrypto_init reads otp.bin and seeprom.bin from the user\ndata path and rejects any size other than 1024 and 512 bytes. Without a\nvalid OTP no certificate is loaded and online mode is off. The certificate\ntable names 8 client certificates with their AES-encrypted RSA keys and 39\nCA certificates, all under sys/title/0005001b/10054000/content/ of the\nMLC, and olive and wood appear twice under distinct ids, so 7 distinct client\npairs and 39 CA files are read. A key file must be a non-empty multiple of\n16 bytes and is decrypted with the key at OTP offset 0x120. Online mode is\nonly enabled when every file of the table is present. For the libretro\ncore these live in the save directory, not the system directory.\nref: src/Cafe/IOSU/legacy/iosu_crypto.cpp:303-330,\n src/Cafe/IOSU/legacy/iosu_crypto.cpp:463-606,\n src/Cafe/IOSU/legacy/iosu_crypto.cpp:608-655,\n src/config/ActiveSettings.cpp:50-55, src/Cafe/Account/Account.cpp:422-458\n\ncafeLibs. When a title depends on a module, the loader first looks for\n.rpl in cafeLibs/ under the user data path and loads it in place\nof Cemu's own implementation, as long as the game profile does not set\nloadSharedLibraries to false (the default is true). Any Cafe OS module can\nbe placed there. The code names snd_user.rpl and snduser2.rpl as the ones\nto dump when a title uses an unsupported audio effect, and gates\nswkbd.rpl and erreula.rpl on the presence of their data packs in the MLC\n(swkbd.pack of title 0005001b-1004f000, erreula.pack of 0005001b-10051000),\nfalling back to the built-in applets when the pack is absent.\nref: src/Cafe/OS/RPL/rpl.cpp:1929-1939, src/Cafe/OS/RPL/rpl.cpp:1971-1991,\n src/Cafe/OS/RPL/rpl.cpp:2142-2154, src/config/ActiveSettings.cpp:57-60,\n src/Cafe/OS/libs/snd_user/snd_user.cpp:1220-1227\n\nData directories. A title's game profile is read from gameProfiles/.ini under the config path, then from gameProfiles/default/.ini under the data path. Upstream ships 236 of them in\nbin/gameProfiles/default and the libretro data path is /Cemu.\nStandalone loads as a graphic pack every directory holding a rules.txt\nunder graphicPacks/ of the user data path, and its downloader extracts the\ncemu_graphic_packs release into graphicPacks/downloadedGraphicPacks/. The\nlibretro core carries its own copy of that set, zipped into the binary at\nbuild time from the dependencies/cemu_graphic_packs submodule. On each\ncontent load it compares the first line of graphicPacks/version.txt with\nthe set it carries and, when they differ, deletes everything under\n/Cemu/graphicPacks and unpacks its set there. A user's own\npacks go in /Cemu/customGraphicPacks, where a folder replaces\nthe bundled pack at the same relative path. The core enables the packs\nflagged default and those switched on through its core options. Miiverse\nposts for The Wind Waker HD are served from resources/miiverse/OfflineDB.zar\nunder the user data path when the Nintendo network service is selected.\nref: src/Cafe/GameProfile/GameProfile.cpp:181-195,\n src/Cafe/GraphicPack/GraphicPack2.cpp:96-111,\n src/gui/wxgui/DownloadGraphicPacksWindow.cpp:133,\n src/gui/wxgui/DownloadGraphicPacksWindow.cpp:234-238,\n src/libretro/embed_graphic_packs.cmake:8-54,\n src/libretro/LibretroGraphicPacks.cpp:30-103,\n src/libretro/CemuLibretro.cpp:6355,\n src/libretro/CemuLibretro.cpp:3541-3582,\n src/libretro/CemuLibretro.cpp:3895-3905,\n src/Cafe/OS/libs/nn_olv/nn_olv_OfflineDB.cpp:21-31,\n src/Cafe/OS/libs/nn_olv/nn_olv_OfflineDB.cpp:124-125,\n src/Cafe/OS/libs/nn_olv/nn_olv_InitializeTypes.cpp:242-248\n\nGenerated, not collected: settings.xml (standalone only), network_services.xml\n(custom service URLs, read when present), controllerProfiles/,\ntitle_list_cache.xml (standalone only, the core keeps no cache), the shader\ncaches, log.txt, sdcard/, dump/, and the language.txt and country.txt that\nthe wx frontend and the libretro core both write into title\n0005001b-1005c000 of the MLC when absent.
