FourDO v1.0.5.0 Alpha is released. FourDO (4DO) is an open-source emulator for the 3DO Game Console.

FourDO v1.0.5.0 Alpha Changelog:
- Added support for joysticks.
- Ability to add multiple links controls.
- Controllers / joysticks that you set will be saved with a unique GUID (provided by DirectInput). This avoids the cumbersome problems in a more simplistic using something like the device number. You should be able to resolve two controllers of the same type 4DO recognize them as a single device. The author finds it convenient, but would like to know if it is for you.
- If a joystick is disconnected while playing, 4DO will not be lost. It will not continue to press the last key pressed, and you can plug the joystick to return to the game
- You can connect a single button on your controller on several real buttons on the 3DO and vice versa.
- Support any axis including accelerometers. The author does not stick with accelerometer, and he would like to get feedback to see if it works correctly.
- You do not need to choose a specific device (keyboard or joystick) when setting a 3DO controller. You can connect both the keyboard and buttons on a controller on the same controller for the 3DO.
- The documentation says SlimDX supports Xbox 360 controllers. So 4DO should also do so. However, the author has not tried.
