i have finished all the content in an older verion of the game and ive downloaded the newer version but i dont know how to transfer my save file over cos i dont really wanna replay the whole game
Ye sorry but i dont think thats actually possible :P.Tho usually le save data transfers itself into the new version.So you might already have all your saved progress in the new version.(Probably)
if you don't want to go all over the game again in a newer version then I recommend just using cheats to unlock everything, you said that you have already finished the game, so you wouldn't be missing anything new.
