OpenBallance
Play Ballance in your browser
OpenBallance runs here as openballance.wasm on the
gasm runtime: the same engine as on the desktop, running the original
game's scripts, levels, textures, sounds and music from your own copy of Ballance.
Nothing from the game is on this site, and nothing you pick leaves your computer.
What you need
- Ballance (Cyparade / Atari, 2004): the folder you installed it to (the one with
base.cmo), the CD (the folder withSetup), or an image of the CD (.isoor a raw.bin). - A browser with WebGPU: a recent Chrome or Edge, Safari 26 or newer, or Firefox 141 or newer on Windows.
- About 150 MB of browser storage: the page copies the data into its private storage for this site once, so later visits start at once.
- A keyboard or a gamepad.
Choose your Ballance
Imported:
The browser may clear site data when disk space runs low.
Or choose the game again below to replace it.
The installed game (for example C:\Program Files\Ballance, with
base.cmo, 3D Entities, Sounds and Textures), or the CD
itself or a copy of it (with Setup\data1.hdr): the game is read straight from the installer's
cabinets, no installation needed.
Importing copies the files into this site's private browser storage (OPFS). Playing without importing reads them from what you picked, which you'll need to pick again next time.
Controls
The game reads the keyboard and the mouse directly, with the original's keys. A connected gamepad works too. More in Controls.
