 # libaaruformat
 
-C implementation of [Aaru](https://www.github.com/aaru-dps/Aaru) file format.
+C implementation of the [AaruFormat](https://github.com/aaru-dps/Aaru) disk image format for the
+[Aaru Data Preservation Suite](https://github.com/aaru-dps/Aaru).
 
-The target is to be able to compile it with a normal C (C89 compliant) compiler.
+Written in C (C99 standard) with no external runtime dependencies. All third-party code is statically
+linked from the `3rdparty/` directory.
 
-There are no external dependencies.
+## Features
 
-cmake is not a hard dependency, it's merely for the ease of using IDEs (specifically CLion).
-
-Currently supported features:
+### Core
 - AaruFormat V1 images reading (writing will never be implemented)
 - AaruFormat V2 images reading and writing
-- LZMA compression
-- Claunia Subchannel Transform
+- Image identification and verification
+- LRU block cache for read performance
+- Large file (>2 GiB) I/O support
+- Feature parity with the C# implementation
+
+### Compression
+- LZMA
+- Zstandard (Zstd)
+- FLAC (for CD audio tracks)
+- Claunia Subchannel Transform (for CD subchannel data)
+
+### Checksums & Hashing
+- Hashing while writing: MD5, SHA1, SHA256, SpamSum, BLAKE3
+- CRC64 with SIMD acceleration (CLMUL on x86, VMULL on ARM)
+- ECC CD checksums
+
+### Erasure Coding & Data Recovery
+- Reed-Solomon error correction with configurable K,M parameters
+- GF(2^8) arithmetic with 4-path SIMD dispatch (AVX2, SSSE3, ARM NEON, scalar fallback)
+- Five protection groups: data blocks, DDT-primary, DDT-secondary, metadata, index
+- Transparent recovery on read
+- Recovery footer at EOF with backup header
+
+### Console Disc Encryption/Decryption
+- **PS3**: Per-sector AES-128-CBC encryption/decryption, encryption map support, IRD file parsing
+- **Wii U**: Two-tier encryption (disc key + per-title keys), WUD/WUX format support
+- **NGC/Wii**: Wii partition encryption, GameCube/Wii LFG PRNG junk detection and generation
+
+### Media & Metadata
 - Optical disc tracks
+- Tape files and partitions
+- Raw flux transition captures (Kryoflux, Pauline, Applesauce)
+- Apple Lisa tag handling
+- Dump hardware lists
+- CHS geometry retrieval and setting
 - XML metadata retrieval (writing will never be implemented)
 - JSON metadata retrieval and writing
-- Hashing while writing (MD5, SHA1, SHA256, SpamSum and BLAKE3)
-- Deduplication
-- Tape file and partitions
-- Dump hardware lists
-- Currently on sync (as of October 2025) with Aaru's media type list
-- CHS geometry retrieval and setting
-- Metadata
-- Unit testing
-- Automatic generation of API documentation
-- It is to all effects feature parity with C#
+- Deduplication (xxHash-based with hash maps)
+- Media type list in sync with Aaru
 
-Things still to be implemented that are already in the C# version:
+### CLI Tool (`aaruformattool`)
+
+Optional command-line tool built with `-DBUILD_TOOL=ON`. Commands include:
+- `identify` — Identify AaruFormat version
+- `info` — Display detailed image information
+- `read` / `read_long` — Read sectors
+- `verify` / `verify_sectors` — Verify image and sector integrity
+- `compare` — Compare images
+- `convert` — Convert between image formats
+- `convert-ps3` — Convert PS3 disc images
+- `convert-wiiu` — Convert Wii U disc images (WUD/WUX)
+- `convert-ngcw` — Convert GameCube/Wii disc images
+- `inject-media-tag` — Add media tags to images
+
+### Platform Support
+- macOS (x86_64, arm64)
+- Linux (x86_64, aarch64, armv7, mips, riscv64)
+- Windows (MSVC, MinGW — x86, x64, ARM, ARM64)
+
+### Developer
+- Unit testing (Google Test)
+- Automatic API documentation generation (Doxygen)
+- Format specification in AsciiDoc (`docs/spec/`)
+
+## Things still to be implemented
 
 - Automatic media type generation from C# enumeration
-- Nuget package for linking with Aaru
-
-Things to be implemented not in the C# version (maybe):
-
-- Compile for Dreamcast (KallistiOS preferibly)
-- Compile for PlayStation Portable
-- Compile for Wii
-- Compile for Wii U
-- Compile for PlayStation 2
-- Compile for PlayStation 3
+- NuGet package for linking with Aaru
 - Snapshots
 - Parent images
 - Data positioning measurements
