Mojave Grand Prix

Fallout: New Vegas x Assetto Corsa Competizione

Gloria Vance has set up a pre-war racing terminal in her garage by the 188 Trading Post. She hands out race contracts in New Vegas. You drive them for real in Assetto Corsa Competizione. When you set a clean lap under her time, the quest updates in the Mojave and she pays you in caps.

| # | Contract | Track | Class | Beat | Pay | |---|---|---|---|---|---| | 1 | Warm-up | Monza | GT3 | 1:53.000 | 250 caps | | 2 | The Ardennes Run | Spa-Francorchamps | GT3 | 2:22.000 | 500 caps | | 3 | The Green Hell | Nurburgring | GT3 | 1:58.000 | 1000 caps |

Requirements

• Fallout: New Vegas (Steam/GOG, Windows)
• Assetto Corsa Competizione (Steam, Windows)
• xNVSE 6.3 or newer
• JIP LN NVSE (recent build with the script runner)

How it works

 Fallout: New Vegas                     MojaveGPBridge.exe                 ACC
 ------------------                     ------------------                 ---
 Gloria's dialogue  --contract.txt-->   reads contract     <--telemetry--  shared memory
 quest stages       <--result.txt---    judges each lap                    (track, car, laps,
 caps & objectives                      (track, class,                     lap validity)
                                         valid, < target)

• Data/MojaveGrandPrix.esp holds Gloria, the quest and her dialogue. It's generated by fnv/build_esp.py, so no GECK is needed.
• Data/NVSE/Plugins/scripts/gr_MojaveGP.txt hooks Gloria's dialogue. JIP's script runner runs it when the game starts.
• Data/NVSE/Plugins/scripts/ln_MojaveGP.txt runs on every new game or load. It places Gloria the first time, re-syncs the bridge, then checks results once a second.
• Data/MojaveGP/MojaveGPBridge.exe reads ACC's shared memory. It counts a lap only if ACC never marked it invalid, it was completed after you accepted the contract, it was on the right track and in the right class, and it was during a live session (not a replay).

Playing

1. Launch with Data\MojaveGP\MojaveGPBridge.exe --launch-acc --launch-fnv. It enables the plugin, starts both games and keeps running until Fallout closes.
2. In New Vegas, go to the 188 Trading Post and talk to Gloria Vance. Pick "Heard you're hiring drivers."
3. Alt-tab to ACC. Start a Single Player Practice or Hotlap session on the contract's track in a GT3 car.
4. Set a clean lap under the target. When you go back to New Vegas, you'll see a lap toast for each lap. On a pass, a message pops up and the objective changes to "Return to Gloria."
5. Talk to Gloria and pick "I beat your time." She pays you and offers the next contract.

Building (macOS/Linux)

./build.sh

Requires Go 1.22+ and Python 3. The output is dist/MojaveGrandPrix/ (the same layout as the Fallout folder) and dist/MojaveGrandPrix-<version>.zip.

To change tracks, targets or pay, edit contracts.json and rebuild. The bridge, quest text, dialogue and scripts all update from it.

Testing on Windows

1. Bridge alone: run MojaveGPBridge.exe --fnv-dir "<FNV folder>", then start an ACC session. Data\MojaveGP\bridge.log should show the state change when you write 12345 1 into contract.txt, and each lap with valid/invalid.
2. Fallout alone (no ACC): run MojaveGPBridge.exe --simulate --launch-fnv. Accept a contract from Gloria. Within about 5 seconds a simulated lap should pass it. Use this to check the whole quest loop.
3. Full run: use --launch-acc --launch-fnv and drive it.

When something goes wrong, check these first: the console output (~), jip_ln_nvse.log in the Fallout folder (script compile errors) and Data\MojaveGP\bridge.log.
