OpenMRac is a split-screen racing game. It is a tweaked source release of MultiRacer.
Programming was done by Vojtěch Salajka.
Porting to big endian architectures for Amiga-like OSes was done by Szilárd Biró.
Creating forks and porting to additional platforms is encouraged, but these typically will not be merged back to the main repo. The same applies to mods.
Franticware claims rights to the name "MultiRacer" which should not be used by other parties for their products or ports. That is the reason for changing the title to OpenMRac, to which no such restrictions apply.
Game data files are in a separate repository under a different license: https://github.com/Franticware/OpenMRac-data
