ResidualVM (formerly Residual) is a cross-platform computer program comprising 3D game engine recreations with a common graphical user interface. It supports Grim Fandango, Myst III: Exile and The Longest Journey. ResidualVM is a reimplementation of the part of the software used to interpret the scripting languages by conducting reverse engineering on the original game rather than emulating the hardware on which the games ran. As such, ResidualVM allows the games it supports to be played on platforms other than those for which they were originally released.
