So I hoped on the bandwagon a wile ago like v35.1 and I wanted to know if I could use the saves I have if I get the newest ver.
[I'm an android user btw]
It will be time consuming and you'll need root access, so you can copy files over from the old version, otherwise it won't load at all.
Even then, the save will be quite bugged, so you'll need to start over with a New Game Plus anyway.
A whole lot of hassle just to keep your items and skills, which aren't that difficult to get back.
Would be much faster to simply make the character again and set your stats manually to what they were before.
