Modern open-source C# .NET 10 Asheron's Call client. Faithful port of retail client behaviour to Silk.NET with a plugin API.

Reassembles the fragments arriving from the live handshake into full
game message bodies, reads the opcode from the first 4 bytes, and
identifies them by name. On the live wire we now see exactly the
sequence ACE sends right after HandleConnectResponse:
GameMessage assembled: opcode=0xF7E5 (DDDInterrogation), body=28 bytes
GameMessage assembled: opcode=0xF658 (CharacterList), body=80 bytes
GameMessage assembled: opcode=0xF7E1 (ServerName), body=20 bytes
summary: 5 packets received, 5 decoded OK, 0 checksum failures,
3 GameMessages assembled
Every layer of the net stack is now proven live:
* NetClient send/receive on both ports 9000 and 9001
* PacketCodec.Encode building LoginRequest + ConnectResponse with
correct unencrypted CRC
* IsaacRandom byte-compatible with ACE's ISAAC (3 EncryptedChecksum
packets decoded, zero mismatches)
* PacketHeaderOptional parsing ConnectRequest, TimeSync, AckSequence
* MessageFragment.TryParse walking a body tail of back-to-back
fragments (the 152-byte packet had TWO messages: CharacterList
and ServerName packed into one datagram)
* FragmentAssembler reassembling by index
The CharacterList body has our test character +Acdream inside it but
we're not decoding its fields yet — that's Phase 4.7 where we actually
pick a character and send CharacterLogin to enter the game world.

acdream
Experimental modern open-source Asheron's Call client in C# / .NET 10.
Status: pre-alpha, not playable. Phase 0 only — dat file asset inventory.
Stack: .NET 10, Chorizite.DatReaderWriter for dat parsing. Silk.NET + Avalonia planned for rendering/UI (not yet wired up).
Requires: A retail Asheron's Call install (Turbine/Microsoft property — supply your own). Set ACDREAM_DAT_DIR environment variable to the directory containing client_portal.dat, client_cell_1.dat, client_highres.dat, and client_local_English.dat, or pass it as the first CLI argument.
Layout
src/AcDream.Cli/— console app that dumps asset counts from a dat directoryreferences/— local read-only reference material (ACE, ACViewer, WorldBuilder, DatReaderWriter, holtburger, retail AC install). Gitignored.
Run
dotnet run --project src/AcDream.Cli -- "C:\path\to\Asheron's Call"
Or set ACDREAM_DAT_DIR and run without args.
