WonderDroid Ultra (formerly WonderDroid X) is an emulator of the Bandai Wonderswan and Wonderswan Color handheld game consoles for Android. It is a fork of WonderDroid, originally written by Daniel Palmer for older versions of Android and later imported from Google Code. I have forked his project to bring it up to date, fix bugs, and improve performance.

Forks or other derivatives of this project may not be called "WonderDroid Ultra", or such confusingly similar name as "WonderDroid Ultimate", or a translation in another language (e.g., "ワンダドロイドウルトラ"). If you publish your app to an app store/catalogue with a name that violates this policy, we will file a report to the owner of the store/catalogue against your app.
