Import december-2020-12-18 from private repo (scrubbed 2026-05-27)

Targets Rec Room 2020.12.18 client.

Re-import after adding:
- DorkNet.ClientMod/dorknet-clientmod.json.template — config schema
  the launcher's manifest-driven patcher renders into UserData/.
- tools/build-patcher-zip.ps1 — produces the dorknet-clientpatch-{key}.zip
  Release asset the launcher fetches.
- .github/workflows/release.yml — auto-publishes both Release assets
  on v1-december-* tag push.

Scrubbed via maintainer-side scrub-for-public.ps1: same drop rules as
the prior import, plus build-patcher-zip.ps1 added to the tools/
allow-list so it survives the scrub.

+.SYNOPSIS
+  Disable Easy Anti-Cheat in a Rec Room 2020.12+ install so MelonLoader /
+  Harmony patches can attach.
+
+.DESCRIPTION
+  The 2020.12+ Steam builds ship EAC, but the integration is the standard
+  EAC-launcher-wrapper model — NOT in-process anti-cheat in the game
+  binary itself.
+
+  Files in a 2020.12 install:
+
+    RecRoom.exe          (~650 KB)  The actual Unity game binary.
+                                    No SteamStub, no EAC strings.
+    Recroom_Release.exe  (~1.2 MB)  The EAC launcher front-end. Steam
+                                    launches this; it reads
+                                    EasyAntiCheat/Launcher/Settings.json,
+                                    talks to the EAC service, then
+                                    spawns RecRoom.exe under EAC.
+    EasyAntiCheat/                  EAC service binaries + the launcher's
+                                    Settings.json.
+
+  EAC blocks foreign DLL injection (MelonLoader's version.dll proxy,
+  Harmony hooks, etc.), which makes a normal Steam launch unrunnable for
+  the modded client. The fix is simple: skip the EAC launcher entirely
+  and run RecRoom.exe directly. EAC is never loaded into the process,
+  no patching of any binary required.
+
+  This script just writes Launch-DorkNet.bat at the install root that
+  starts RecRoom.exe directly with any flags you pass through. The
+  EasyAntiCheat/ folder and Recroom_Release.exe are left in place —
+  they're harmless when nothing invokes them, and leaving them avoids
+  tripping unrelated existence checks.
+
+  Designed for use with a DorkNet private server only — EAC's whole
+  point is the official live game. On a self-hosted server where every
+  client talks to YOUR backend, EAC isn't doing anything useful.
+
+.PARAMETER RecRoomDir
+  The Rec Room install root (the folder containing RecRoom.exe,
+  EasyAntiCheat/, RecRoom_Data/).
+
+.PARAMETER Revert
+  Remove the Launch-DorkNet.bat shortcut. (There's nothing else to
+  undo — the script never touches the game files.)
+
+.PARAMETER WhatIf
+  Show what would be done without touching the filesystem.
+

+  # Set up direct launch on a 2020.12 install
+  .\tools\remove-eac.ps1 -RecRoomDir 'C:\Games\RecRoom'
