Writes the title's internal 'live user' flag byte (0x83028851, derived from
sub_8263E788's lis -32003 / lbz -30639 = recompiler value -2097348608 ->
0x83030000 - 0x77AF) to 1 so the frontend stops refusing Xbox Live features
before it ever calls a rexglue API. Logs the first force.
- Deadlock: SetRelay held the transport mutex while join()ing the receive
thread, which needs the mutex to observe running_ and exit. With the 200ms
recv timeout the thread woke and hit the lock -> a room/server change froze
the game (every room keystroke reconnects the transport). StopThread now
detaches the thread under the lock and joins WITHOUT it.
- XamUserCheckPrivilege denied everything, which is the gate the game's
'create a party' flow checks (multiplayer sessions); grant requested
privileges so the P2P session flow opens, and log the mask.
- #pragma pack(push,1) on the wire structs (the relay's proto is packed; the
transport's were not, which would inflate sizes and corrupt every datagram)
plus static_asserts pinning sizes to 7/31/1410/25/801.
- Heartbeat re-JOIN every 4s so the relay never times the transport out.
- REXLOG info for connect/join/session-reply so the flow is observable.
Route the game's own RakNet UDP through the ghost relay so real internet
peers can play, with the server as a pure relay/NAT stabilizer:
- XNetTransport: a rexglue relay client (joins the same relay + room as the
ghost client), a receive thread, and:
- SendGame(): wraps a datagram addressed to a virtual 10.80.0.x peer in a
relay Game payload and sends it OUTBOUND to the relay (no inbound
reachability / port forwarding needed).
- QuerySessions()/Sessions(): discovery - the room members that
XNetQosLookup reports to the game's session search.
- Receive injection: relayed Game payloads are pushed into the game's
registered sockets via XSocket::QueuePacket.
- XSocket: SendTo() to a virtual address routes through the transport;
RecvFrom() drains queued relayed packets first; sockets register with the
transport on Initialize.
- XNetQosLookup: queries the relay and returns the room's members as
discovered sessions (with their virtual addresses), signaling completion.
- XNetGetTitleXnAddr identity now shares one source of truth with the
transport (same 10.80.0.x).
Wire structs are minimal copies of the game's ghost protocol (kept
dependency-free); the relay's version check refuses mismatches.
