Cor-Son Games

Cor-Son Games was a game developer owned by The Corning/Emerson Group. It existed as early as 1983 as a developer of text-based adventure games before they were bought out in 1990. Under the Cor-Son moniker, they produced licensed titles and games within the Alison and Colleen series. They have collaborated with other developers on their games, mainly acting as a quality tester while also providing assets to the final product before it's shipped to the public. The label shut down in 2008 after Nintendo successfully sued them for trying to sabotage their console sales.

Their games were only released in North America, Europe and Oceania.
