-# Red Planet 4.12
+# Red Planet 4.12 — the Steamification
 
-**Red Planet** is the VWE pod-racing game built on the in-house **MUNGA** engine
+**Red Planet** is VWE's pod-racing game: eight-player VTV races on Mars,
-(Win32 / DirectX 9, `MUNGA_L4` platform layer). The **4.12** line is the
+originally played from inside VWE Tesla cockpit pods. This repo is the
-consumer port: a version of Red Planet that can be **sold on Steam** and played
+third life of that code:
-over **internet multiplayer**, without cockpit-pod hardware.
 
-Forked from [RP411](https://gitea.mysticmachines.com/VWE/RP411.git)
+| Generation | What it was |
-(the arcade/cockpit 4.11 line) with full history preserved.
+|------------|-------------|
+| **Red Planet 4.10** | The original game, running on the **Tesla 1** pod platform (DOS-era MUNGA engine, serial RIO cockpit hardware, operator console, batch-file relaunch between missions) |
+| **Red Planet 4.11** | The **Win32 port** of 4.10 ([RP411](https://gitea.mysticmachines.com/VWE/RP411.git)) — DirectX 9, WinSock TCP, TeslaConsole/TeslaLauncher session control; still runs in pods, still a LAN |
+| **Red Planet 4.12** | **This repo: the Steamification of 4.11** — the same engine, the same wire protocol, the same missions, made distributable on Steam and playable over the internet with no cockpit hardware |
 
-## Goals
+The architecture is deliberately conservative: the VWE's design survives
+intact, with each pod-era dependency replaced by a consumer equivalent
+behind the engine's existing seams.
 
-1. **Steam distribution** — Steamworks integration, SteamPipe builds, store-ready packaging.
+| Arcade (4.10/4.11) | 4.12 replacement |
-2. **Internet multiplayer** — take the engine's LAN-era WinSock networking online
+|--------------------|------------------|
-   (NAT traversal, matchmaking, latency tolerance).
+| RIO cockpit board (serial) | **PadRIO** — virtual RIO from XInput pad + keyboard, fully rebindable (`bindings.txt`, vRIO profile format) |
-3. **No cockpit required** — keyboard / mouse / gamepad input and on-screen
+| Seven physical displays | **Single-window cockpit** — all displays composed on a locked 1920×1080 canvas around the viewscreen, with the real button banks lamp-lit and clickable |
-   replacements for the pod's RIO panel and plasma display, drawing on
+| Pod button lamps | On-screen lamps, plus an **RGB keyboard mirror** (Windows Dynamic Lighting) |
-   [vRIO](https://gitea.mysticmachines.com/VWE/VRIO.git).
+| TeslaConsole operator | **In-game front end** — race setup menu builds the mission egg locally; an in-process console marshals every race (missions still only end on a console stop, exactly as designed in 1994) |
-4. **Self-hosted sessions** — in-game race setup/join replacing the operator-driven
+| TeslaLauncher relaunch-per-mission | **Single binary** — menu → race → results → menu in one process |
-   [TeslaConsole](https://gitea.mysticmachines.com/VWE/TeslaSuite.git) flow.
+| WinSock TCP LAN mesh | **NetTransport seam** — the deterministic pod mesh unchanged, running over plain TCP (LAN/dev) or **Steam Networking Sockets** (FakeIP + Steam Datagram Relay) |
+| Site network / fixed IPs | **Steam lobbies** — lobby owner is the console; members exchange FakeIPs and loadouts as lobby data |
 
-See [docs/RP412-ROADMAP.md](docs/RP412-ROADMAP.md) for the plan and the
+**Status: it works.** Release
-Steam-multiplayer logistics.
+[v4.12.2](https://gitea.mysticmachines.com/VWE/RP412/releases/tag/v4.12.2)
+carries the first verified end-to-end internet build: three machines, three
+Steam accounts, lobby → mesh → marshaled five-minute race → deaths and
+respawns → timed stop → results on every machine → rematch from the same
+lobby.
+
+## Playing
+
+Grab the release zip (or run `pack-dist.ps1` on a build). Single player:
+run `start-windowed.bat` — the game boots into the race setup menu. Steam
+multiplayer: see
+[docs/STEAM-3-MACHINE-TEST.md](docs/STEAM-3-MACHINE-TEST.md) (until RP412
+has its own AppID it runs under Spacewar, 480).
+
+The two config files beside the exe are self-documenting: **environ.ini**
+(every engine option, commented) and **bindings.txt** (every key, pad
+button, and axis; written with the full default layout on first run).
+Default controls: numpad flies (8/2/4/6 stick, 7/9 pedals, 0 trigger),
+Shift/Ctrl throttle, Alt reverse, arrows look, Space fires, letter rows
+are the MFD button banks as printed on the panel. **Alt+Q** aborts a
+mission.
 
 ## Building
 
-Unchanged from 4.11 for now — see [BUILD.md](BUILD.md)
+**VS 2022 (v143)** + DirectX SDK June 2010 + the vendored Steamworks SDK
-(VS 2005/2008 + DirectX SDK June 2010, `Release|Win32`, output `Release\rpl4opt.exe`).
+(`extern/steamworks_sdk_164`) — see [BUILD.md](BUILD.md). Solution
-Toolchain modernization is a roadmap item.
+`WinTesla.sln`, configuration `Release|Win32`, output
+`Release\rpl4opt.exe`.
