4D/Stunts Replay Data Viewer, or RPLINFO in short, was made by Lukas Loehrer. RPLINFO is a utility that allows you to view some data of replay files (*.rpl), and also lets you extract the track from recorded replay.

The program was released for DOS, Windows (16bit and 32bit versions) and Java (very experimental) systems.
