The file must start with WADF0100 and declare at offset 20 a size within its own length. Each record is a u32 name length, the name, one byte, a u32 data length and the data, and a zero name length ends the table. Names are lowercased, backslashes turned to slashes and a leading drive letter dropped, so Z:\\SYSTEM\\nls\\c_936.nls and system/nls/c_936.nls reach the same entry. The archive is the last source consulted when a game opens a file the save directory, the content directory, the package's resources and its appended zip payload do not hold. Without it such an open fails and the runtime goes on. The image itself is never hashed, and the hashes here name the last firmware Gemei published, and the V1.10 image of 2011-01-25 indexes the same way.",

The CCDL package's load\naddress selects the runtime: a .app loaded in the 0x8xxxxxxx range runs on\nthe MIPS32 interpreter as an A320, a .cc, .c2s or .c3s loaded at\n0x10100000 (retail SDK) or 0x13800000 (homebrew SDK) runs on the\nARM32/Thumb interpreter as an A330\n(crates/dingooemu-core/src/content.rs:66-74, 104-121,\ncrates/dingooemu-core/src/emulator.rs:44-55).

A name none of\nthem answers fails the open. fsys_findfirst enumerates the content's\ndirectory and refuses to leave it\n(crates/dingooemu-core/src/a330/runtime/sdk_hle/files.rs:381-395).\n\nFiles the game creates land in the frontend save directory\n(crates/dingooemu-libretro/src/api.rs:150-155,\ncrates/dingooemu-core/src/emulator.rs:173-179) or, when the frontend\ngives none and in the standalone, beside the content\n(crates/dingooemu-core/src/a320/runtime.rs:372,\ncrates/dingooemu-core/src/a330/runtime.rs:415-417).
