This mod gives you almost infinite rewinds (999) useful for training.
Overwrite DATA.MIX in the main MotoGP15 folder.
This will overwrite and make inactive any other mod that uses DATA.MIX
If you do not see 999 rewinds, please try to change rewinds counts in driving assist menu two or three times. You will always see just "0". Then in game you will have 999 rewinds.
