NTE History Exporter # NTE History Exporter Prototype CLI exporter for **Neverness to Everness** pull history — decodes your own game traffic into sanitized JSON ready for tracker import. ![Python](https://img.shields.io/badge/python-3.10+-blue) ![Platform](https://img.shields.io/badge/platform-Windows%20%7C%20Linux%20%7C%20macOS-0078D6) ![Status](https://img.shields.io/badge/status-prototype-orange)
## Supported Banners | System | Banner | Banner ID | Pity pool | | -------- | ----------------------- | -------------------------- | ---------- | | Monopoly | Standard Board | `Lottery_Permanent` | Per-banner | | Monopoly | Limited Character Board | `Lottery_LimitedCharacter` | Shared | | Gashapon | Arc Miracle Box | `Arc_MiracleBox` | Shared | ## What It Does The exporter decodes Permanent Board, Limited Character Board, and Arc Miracle Box history pages from captured UDP data, applies conservative timestamp-boundary handling, and writes sanitized JSON suitable for tracker import. > [!NOTE] > The import JSON contains decoded history rows only. It does **not** export tokens, account IDs, role IDs, device IDs, server IPs, raw packets, cookies, session data, or any other capture metadata. ## Requirements - Python 3.10 or newer. - Packet-capture permission: Administrator on Windows, or root/capture capabilities on Linux and macOS. - **Windows:** [Npcap](https://npcap.com/) is recommended. Install it normally; WinPcap API-compatible mode is not required. If Npcap is unavailable or cannot be initialized, `auto` falls back to the Windows built-in raw-socket backend. - **Linux:** install the system **libpcap** runtime if it is not already present. Package names commonly include `libpcap0.8` on Debian/Ubuntu and `libpcap` on Fedora, Arch, and similar distributions. - **macOS:** the system normally includes **libpcap**, so no separate Npcap installation is needed. Npcap is Windows-only and is not bundled with this project. Linux and macOS use libpcap, the cross-platform capture library on which Npcap is based. ## Usage ### Live capture The default `auto` capture backend uses: - **Windows:** Npcap when installed, with automatic fallback to the built-in Windows raw-socket backend. - **Linux/macOS:** the system libpcap library. Use `--capture-backend libpcap` to require Npcap/libpcap without fallback, or `--capture-backend raw` to require the Windows raw-socket backend. #### Windows (requires Administrator) ```powershell .\run-exporter.ps1 --live ``` Or simply double-click **`run-exporter.cmd`** — it asks for confirmation before requesting Administrator privileges, and does nothing until you agree. > [!IMPORTANT] > Launch the tool **before pressing Start on the game's main menu** so the game's UDP connection can be captured. If you are already in game, log out to the main menu and enter again. Once running, open any supported history board in game. The tool keeps listening until you press any key. Exports are written under `exports\` as: - `Permanent_.json` - `Limited_.json` - `Arc_.json` If only one banner is captured, the export JSON is copied to your clipboard. If multiple banners are captured in the same run, clipboard copy is skipped so one banner does not overwrite another. If a page response is missed, the exporter reports the missing page number while capture is still running. Leave the exporter open, close and reopen that history board, then scroll down again. Scrolling backward within the existing view does not request the cached pages again. The replacement capture is accepted and the tool confirms when the gap has been recovered. If reopening the board still produces no page messages, return to the main menu and re-enter the game to start a fresh connection. #### Linux/macOS Install the project and ensure the system libpcap runtime is available: ```bash python3 -m venv .venv source .venv/bin/activate python -m pip install -e . sudo .venv/bin/nte-history-exporter --live ``` macOS normally includes libpcap. On Linux, install the distribution's libpcap runtime package if it is not already present. Capture can also be granted through platform-specific capabilities instead of running the whole exporter with `sudo`. ### File replay ```powershell .\run-exporter.ps1 capture.flows ``` Decodes a `mitmproxy .flows` capture instead of listening live — used for research and testing. ### Options | Flag | Effect | | --------- | --------------------------------------------------- | | `--live` | Capture live UDP traffic instead of reading a file. | | `--debug` | Also write the full research CSV next to each JSON. | Advanced live-capture selection: ```text --capture-backend auto Prefer Npcap/libpcap; fall back to raw sockets on Windows --capture-backend libpcap Require Npcap on Windows or libpcap on Linux/macOS --capture-backend raw Require the Windows raw-socket backend ``` The `--debug` CSV holds any extra information that might be needed for fixing bugs. It contains no dangerous personal account data — only the raw bytes of the captured history page. > [!TIP] > For reliable deduplication, start from page 1 and scroll through the pages. If you only want pages 1–5, scroll through to page 6 as well just to be on the safe side. ## Privacy > [!CAUTION] > Do not commit packet captures, generated exports, research briefs, or personal account data. The repository keeps `exports/` as an empty output folder but ignores everything generated inside it. ## Boundary Policy NTE history records do not appear to contain a unique server-side roll ID. UIDs are generated from decoded record fields and the record's order within all rows sharing the same raw timestamp. History always loads page 1 first and is scrolled downward, so the exporter anchors to the continuous run of pages starting at page 1 and ignores anything after the first gap (with a warning). This keeps the newest pages even if a later page is lost, and guarantees the newest timestamp group's ordinal 0 is captured. Within a timestamp group, ordinal 0 is the newest record and unseen rows can only append after the captured ones, so **every exported UID is stable** — including a partially captured oldest 10-pull. All decoded rows are therefore exported. Re-scanning later simply adds any rows that were not yet captured, with the same UIDs for the rows already seen. For Monopoly, Points Gift and Chase Reward rows stay in the timestamp group for UID ordinal generation, but only `result_type = dice` rows count toward pull-set sizing. Arc pulls are always 10-pulls. In both systems every captured group is exported, including the oldest one even if it is a partially captured pull set, because its captured prefix is ordinal-stable. ## Adapters **Current** - Live Npcap/libpcap capture on Windows, Linux, and macOS - Live Windows raw-socket fallback - `mitmproxy .flows` research decoder **Planned** - Optional pktmon diagnostics for capture-drop investigation - UI wrapper around the CLI ## Example Run
