One-click installer for YSM, YSM x WiF, YSM x WiF x WTO, and WTO. Finds your game, picks the right mod version, installs it safely, and leaves your save/config untouched.
- Finds WARNO automatically — works with Steam, non-Steam, and portable installs. If it misses, point it to
Warno.exemanually or run a full-drive scan. - Handles multiple WARNO copies — picks them all up and lets you choose which one to mod.
- Knows the right mod for your version — if WARNO is newer than the catalog, the installer falls back to the latest compatible mod and warns you. A built-in guide shows how to switch WARNO versions via Steam betas.
- "Choose a build" screen when several mods fit your WARNO version — with download sizes shown up front.
- Bring your own — install from a local folder or archive (
.zip,.7z,.rar) if you already have one. - Known-issues link — if your version has known issues, you get a one-click link to the workshop discussion before installing.
- Safe install — closes WARNO first, backs up your current mod config, and rolls everything back if anything fails.
- Cancel anytime — the progress bar has a Cancel button. Canceling restores the previous state.
- Clear errors — if the installer can't reach the internet, it tells you whether you're offline, the mod host (GitHub or Google Drive) is down, or just the mod list is broken, instead of a cryptic error.
- Auto-updates — checks for new installer versions on startup and shows the release notes before updating.
- Settings — switch between the official mod list and Yokaiste's GitHub releases as the source.
- Windows 10 or newer
- Internet connection
The installer goes online only to:
- get the list of supported mod versions
- download the mod archive you chose (from GitHub or Google Drive, depending on the build)
- check for installer updates
