As you can see the proyect has been started today... I've already coded the questions database parser (it toke me about 120 lines of code) and I'm starting with the main UI, I hope I will be able to show you soon some screens of it ;-)
Later I'll add some other features like sound and multiplayer suport with some other devices such as a joystick. I'm looking for some methods of encryption for the database of questions and the images, I'll keep you up to date :-)
