In the late 1990s, Superior sub-licensed the games to ProAction who released a number of RISC OS ports for the Acorn Archimedes and RiscPC. John Wallace created new ports of "Repton", "Repton 2" and "Repton 3". ProAction also released "Desktop Repton" which includes the 3 games (including the expansion games for "Repton 3"). These games were built from scratch by Darren Salt, and developed to run in a multi tasking window on the desktop. There was also "Desktop Repton Plus", with new PC graphics and extra levels included for "Repton 1".
