This is a sprite and scroll engine written around the Virtual Boy graphical arquitecture.
Jorgeche's goal is to to create an engine that could be used later by anyone who wants to create a game without having to deal with the display arquitecture but instead, focus on the gameplay aspects.
Jorgeche released two demo games for the engine:
Mario VB (including complete source)
To work correctly, it needs at least Reality Boy v0.822 alpha.
