CydandClaude Fable 5 22421fb418 NetTransport seam: the wire moves behind an interface
The Steam-multiplayer prerequisite from the design doc: L4NET keeps
hosts, message queues, and the deterministic mesh ordering, while
connect/listen/accept/close, send/receive, startup/cleanup, the local
interface list, and ip[:port] parsing move behind NetTransport
(L4NETTRANSPORT.h). WinsockNetTransport carries the existing TCP
behavior over verbatim - including the connect retry-while-refused
loop the egg-ACK ordering relies on - and is the process default;
NetTransport_Set installs a replacement before the network manager
comes up.

L4STEAMTRANSPORT.h documents the ISteamNetworkingSockets mapping
per method (FakeIP keeps [pilots] entries as IPv4 strings) behind
RP412_STEAM until the Steamworks SDK lands.

Also fixed in passing: the ExclusiveBroadcast path sent
sizeof(network_packet) - four bytes of pointer - instead of the
message size, which would have sheared the stream framing had it
ever fired.

Verified: single-player race cycle (menu, race, results, menu, race)
green; -net 8000 boots, listens for a console through the transport,
and idles stable.

Red Planet 4.12

Red Planet is the VWE pod-racing game built on the in-house MUNGA engine (Win32 / DirectX 9, MUNGA_L4 platform layer). The 4.12 line is the consumer port: a version of Red Planet that can be sold on Steam and played over internet multiplayer, without cockpit-pod hardware.

Forked from RP411 (the arcade/cockpit 4.11 line) with full history preserved.

Goals

  1. Steam distribution — Steamworks integration, SteamPipe builds, store-ready packaging.
  2. Internet multiplayer — take the engine's LAN-era WinSock networking online (NAT traversal, matchmaking, latency tolerance).
  3. No cockpit required — keyboard / mouse / gamepad input and on-screen replacements for the pod's RIO panel and plasma display, drawing on vRIO.
  4. Self-hosted sessions — in-game race setup/join replacing the operator-driven TeslaConsole flow.

See docs/RP412-ROADMAP.md for the plan and the Steam-multiplayer logistics.

Building

Unchanged from 4.11 for now — see BUILD.md (VS 2005/2008 + DirectX SDK June 2010, Release|Win32, output Release\rpl4opt.exe). Toolchain modernization is a roadmap item.

Repo Role
RP411 Upstream arcade source (this repo's base)
VRIO Virtual RIO panel + vPLASMA display — input bindings and display emulation to fold in
TeslaSuite TeslaConsole / Launcher / vPOD — the arcade session-control stack 4.12 replaces (and a reference for the Munga control protocol, TCP 1501)
