Rival Engine — The Next-Gen Modding Tool (2025) v2025.7.0

Rival Engine v2025.7.0 — Cross-Platform + Manifest Support​

This release delivers an operational, file-based mod manager for Windows and macOS, plus a mobile PWA companion. It also adds manifest-aware installs for clean, predictable file placement.

What’s new​

• Cross-platform desktop app (Windows + macOS)
• Manifest support (mod.json) for explicit file mapping
• Operational ZIP install: copies into bound game directory
• Automatic backups before overwrite, with one-click restore
• Safe extraction (blocks path traversal; ignores docs)
• PWA companion for mobile (manage/pair; not for applying mods)

Setup​

Windows/macOS (Desktop)

Code:

cd desktop/electron
npm install
npm start

Optional bundling:

Code:

# Windows
npm run pack:win

# macOS (Apple Silicon + Intel)
npm run pack:mac

Note (macOS): the app is unsigned for testing. Use Control-click → Open the first time.

Mobile (PWA)

1. Upload /mobile/pwa/ to your site (e.g. /apps/rival-engine/)
2. Open that URL on your phone → “Add to Home Screen”

Using mod.json​

Place a mod.json at the ZIP root to map files:

JSON:

{
  "name": "Cinematic Pack",
  "version": "1.0.0",
  "maps": {
    "Paks/Mod_Cine_P.pak": "BlackMythWukong/Content/Paks/~mods/Mod_Cine_P.pak",
    "reshade.ini": "reshade.ini"
  }
}

• Keys = paths inside the ZIP.
• Values = relative paths under the bound game directory.
• Non-mapped files fall back to folder-relative placement.

Important​

Rival Engine is intended for single-player / offline modding. It does not patch live memory or interact with anti-cheat.

We’ve pushed a major new update to Rival Engine with big improvements:

• Auto-detect support — scans Steam, Epic, GOG, and Ubisoft libraries for installed games
• Starter library pre-loaded (Black Myth: Wukong, Cyberpunk 2077, Elden Ring) so your Library isn’t empty on first launch
• Mods Manager improvements — clearer queue system and ZIP preview
• Smart Profiles upgraded — improved saving, importing, and sharing of loadouts Integrity Snapshots — create/restore multiple
• restore points quickly UI refinements — consistent Rival Gaming dark theme + gradients across all screensCombined release
• ZIP — now includes both Desktop (Windows) and Mobile (PWA) apps in one download
