Erik f466c337ce sky(phase-3c.1): feed AbsoluteYear (Year+ZeroYear) to retail LCG picker 
Live verification (2026-04-23, Phase 3c launch): acdream picked
DayGroup[17] "Rainy" for PY106 day46 while retail at the same server
tick showed clear blue sky with white clouds (Sunny-ish). Root cause:
our port passed the RELATIVE year (106, i.e. years since tick-0) into
the LCG seed, while retail's TimeOfDay+0x64 is ABSOLUTE Year =
floor(...) + ZeroYear (baseYear=10 for Dereth GameTime). The offset
seeds the LCG with `seed = 106×7620+46` vs retail's `seed =
116×7620+46` — `10 × SecondsPerDay = 76200` apart, guaranteed to
land on a different DayGroup index.

Fix:
- DerethDateTime.ZeroYear constant (= 10) + AbsoluteYear(ticks) helper.
- GameWindow.RefreshSkyForCurrentDay feeds AbsoluteYear into the picker.
- LoadedSkyDesc.ActiveDayGroup(ticks) same.
- Calendar display and generic Year(ticks) stay relative; only the
  LCG-seed path uses the offset. Matches retail FUN_005a7510:5300 which
  explicitly adds baseYear to the relative year before stashing in
  TimeOfDay+0x64.

Build + 717 tests green. Next visual check should show matching
weather with retail client side-by-side.

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 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.
