This mod gives you almost infinite rewinds (999) useful for training.
It is not perfect: you must enter driving assists menu and change "rewinds" a couple of time and try. In menu is "999", but in summary it could be "0" or "7", anyway then it should works.
Overwrite DATA.MIX in the main MotoGP13 folder.
NOTE: This mod is NOT compatible if you have any other control-physics-ai mods.
It will overwrite any other mod that uses DATA.MIX file.
