iam567/rich4-renew-app

A nostalgic fan project: if you want to replay 大富翁4 with sharper art and extra modes, this builds a playable app, but it depends on separately downloaded assets and on-device packing.

The problem

A player who wants an updated version of 大富翁4 normally has to emulate the original or wait for a commercial re-release. Here the author reconstructs the game rules from the original through reverse engineering and rebuilds the board, property, stock, card, item and event systems as a TypeScript game, then wraps it with Capacitor as an iOS app (Android project also present). The result is a playable remake with high-resolution art and additional content rather than a straightforward port.

What's different

The rule layer is the centerpiece: the README says rules were restored from the original disassembly, and documents them under docs/rules/. Beyond the base game, the project adds a 大富豪模式 with 12-player national battles across Tokyo, Osaka, Sapporo, Kyushu and Okinawa, plus a new Kabukicho map with its own event system and building style. That gives returning players something other than the same board.

The trade-off is packaging. The repository contains code, not the full art set: original extracted assets, redrawn high-resolution art, maps, terrain and sound effects live in a Releases tarball, and the game will not run meaningfully until you download that file, check its checksum and extract it into game/public. The map-authoring and image-generation tools are explicitly not part of this repository.

Who should try it

Good fit: a developer or tinkerer who already knows 大富翁4, is comfortable with Node and Capacitor, and wants to read or extend the rule engine and event systems, or side-load a build onto their own phone. The documented path packs an Android APK and an unsigned iOS IPA, and there is a script to install directly to a connected iPhone.

Poor fit: someone expecting a store-ready app or a one-click download. You need to fetch assets from Releases, and the iOS route involves signing and a connected device. Anyone who only wants to play casually without touching code will find the setup heavier than launching an emulator.

Requirements and limitations

You need Node/npm and a Capacitor-capable environment; installing to a physical iPhone requires a connected device and working iOS tooling, and the packaged IPA is unsigned. This is not a ready-to-ship product.

Licensing is split. The source is GPL-3.0-or-later, with rule research referencing mytbk/rich4, but the original 大富翁4 assets and their redraws in Releases are outside that license and the README states they are for private use only. Treat distribution of builds containing those assets accordingly. The project is an actively evolving hobby remake; the README describes more content as something the author will add over time, so expect incompleteness rather than a finished product.

HotRepo's take

HotRepo has tracked this repository only since 2026-10-24; at 8 days old it recorded 301 total stars at #25 on the NEW-REPOSITORY board (新项目榜, TypeScript) on 2026-10-25, not a daily overall Trending rank. That is a snapshot of new-project attention, not growth, and the evidence is insufficient to judge persistence. Before investing time, check whether the Releases asset tarball matches the current code and whether the rule docs cover the modes you care about.
