I think the patch is separate from Tunngle. Maybe the Tunngle patch is a modified version of Tunngle that includes the keyboard support settings pre-configured for FIFA 11. Or maybe users use Tunngle to set up their local network and apply the patch to enable keyboard. It might require some configuration in the game's settings via the patch to map keys correctly.
Wait, but I need to make sure the information is accurate. For example, Tunngle is a program that creates local networks for online gaming, allowing people to connect as if they were on the same network, making it easier to host games without internet lag. But how does it specifically enable keyboard support in FIFA 11? Is it the patch that enables keyboard support, or Tunngle itself? FIFA 2011 -Keyboard Patch Tunngle for fifa 11-
I need to explain all that in layman's terms. Maybe compare it to how people use XInput wrappers or DirectInput to make keyboards and mice work in games that don't support them. I think the patch is separate from Tunngle
