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

Root cause of the still-purple-haze symptom AND the ACE-side
"Network Timeout" drop after ~60s. acdream was never sending
acknowledgement packets back to the server, so the server's
reliability layer saw a one-way stream and eventually dropped the
session. During the 60s window the player rendered to other clients
as the stationary purple loading haze (AC's "this client is in
portal-space transition" indicator).
Pattern ported from
references/holtburger/crates/holtburger-session/src/session/
{send.rs::send_ack, receive.rs::finalize_ordered_server_packet}.
The proper holtburger pattern is per-packet acks, NOT a periodic
heartbeat: every received server packet with sequence > 0 and no
ACK_SEQUENCE flag of its own gets a bare control packet sent back
with:
PacketHeader {
Flags = ACK_SEQUENCE (0x4000),
Sequence = current_client_sequence (= last issued, no increment),
Id = session client id,
}
Body = u32 little-endian server sequence being acked
Acks are cleartext control packets (no EncryptedChecksum) and
re-use the most recently issued client sequence rather than
consuming a new one — they aren't part of the reliable stream the
server tracks for retransmits.
Wired into ProcessDatagram so both Tick (post-InWorld) and PumpOnce
(during Connect/EnterWorld) trigger acks on every received non-ack
server packet.
Also (per user request) upgrades the CLAUDE.md description of the
holtburger reference repo from "Rust AC client crate" to "almost-
complete Rust TUI AC client — the most authoritative reference for
client-side behavior in the project, look here FIRST for anything
WorldSession or message-builder related." This was the third time
in two days I would have saved hours by checking holtburger first
instead of guessing at the protocol from ACE alone.
220 tests green.

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.
