Erik 8356fe65a0 feat(app): load landblock from dats and upload mesh to GPU 
GameWindow now owns a DatCollection + TerrainRenderer. On load it
opens the dat directory passed as argv[0] (or ACDREAM_DAT_DIR), finds
Holtburg (landblock 0xA9B4FFFF) by default with a fallback to the
first landblock in the cell b-tree, builds the CPU mesh from
LandblockMesh.Build, and uploads VBO+EBO+VAO with a 3f/3f/2f attribute
layout. No draw call yet — shader and matrix uniforms land in Task 9.

Enabled AllowUnsafeBlocks on the App csproj so the fixed-buffer upload
in TerrainRenderer compiles. Uses dats.Get<LandBlock>(id) instead of
TryGet(..., out T) to sidestep the [MaybeNullWhen(false)] analysis that
TreatWarningsAsErrors was flagging.

Smoke verified against the real retail dats: prints
"loaded landblock 0xA9B4FFFF" and the window stays alive with no GL
errors or exceptions.

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 directory
  • references/ — 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.
