Oni

What works

The game

What does not

The original retail version of Oni uses an old copy protection program that is not working under wine.

Oni is not supported on modern systems, the most notable bug is a buffer overflow that happens when too many OpenGL extensions are supported by the video card (basically any modern video card).

Additional Comments

Since Oni is not working on modern systems, a certain number of unofficial patches exists. You likely need one of them to run Oni. If your version of Oni is not copy-protected, you can run it without patches, if you disable as many OpenGL extensions as possibile in the wine registry, see http://wiki.winehq.org/UsefulRegistryKeys .

There are multiple known issues with running Oni on some systems (mostly with recent NVIDIA cards) and it is not officially supported on modern hardware. Major problems:

• Oni tries to allocate the available OpenGL extensions in a fixed size array, that is too small for many modern implementations of OpenGL. An unofficial and unsupported patch by Ian Patterson exists and you can download it from here. There are many other patches available on the net.
  
• Some releases of Oni use an old and defunct copy protection (codelok). In that case you may need for a nocd (unofficial and unsupported) patch, because very likely Oni won't work. Remember that English language patch doesn't support special characters (like accented letters or umlaut) and that the Russian one supports all characters (cyrillic, umlauts, accents).
• If you experience sluggish controls and you are using an nvidia card, select the "Sync to VBlank" option in your nvidia control panel.
