Ynis Witrin - Isle of Glass

An obscure 1991 Atari ST action-RPG by Funny Man Software. The 13 Treasures of Arthurian Britain are scattered across a huge map - explore it overhead, then hit Magnify to drop into close-up Gauntlet-style brawls. Rated 92% by ST Format, and almost impossible to find information about today.

Playable below Free - runs in browser Atari ST (1991) Action-RPG Single player

The original Atari ST disk running in a browser emulator. After the desktop loads, double-click the YNIS WITRIN disk, then START_UP.PRG.

Playing: Ynis Witrin - Isle of Glass

Starting the game inside the emulator

The disk boots to the classic green Atari ST desktop rather than straight into the game - two double-clicks get you in.

  1. 1
    Wait for the green desktop

    The emulator loads a real Atari ST boot. Give it 10-20 seconds until the Desktop/File/View/Options menu bar appears.

  2. 2
    Open the YNIS WITRIN disk

    Double-click the disk icon labelled YNIS WITRIN. A window opens showing the disk contents.

  3. 3
    Run START_UP.PRG

    Double-click START_UP.PRG (or similarly named .PRG file) in that window. The game itself takes over the screen from there.

Controls: the game was built for a joystick - the emulator maps it to your keyboard automatically (arrow keys move, and a nearby key such as Ctrl or Space acts as fire). Click the canvas once if key presses do not register.

Is this a new game?

No. Ynis Witrin - Isle of Glass is a 1991 Atari ST game by Funny Man Software. Search results sometimes mix it up with unrelated newer titles - the Arthurian treasure hunt on the green ST desktop is the real thing.

Can I download it instead?
