So, I have save files on my old Wii for Just Dance 4,14,15,16 and I want to import them into those respective games on the wiiu (digital, if it matters). I am starting with the assumption that the save file formats for the Wii and WiiU versions of the game are the same. My first attempt only resulted in corrupted save errors, though I didn't expect it to work anyway tbh, mostly because there are several files I am just ignoring. What I tried: 1. Use SaveGameManagerGX on Wii to backup the save for Just Dance whatever. This results in the following directory structure and files: 2. Use saviine on WiiU to backup newly created saves from JD games. Directories/files: 3. Copy over common files from Wii save folder to WiiU save folder. JD4: slt_0_0.sav, index.dat JD14,15,16: JDSave_0 4. Use saviine on WiiU to restore modified backups. 5. Get corruption errors. I am thinking the other files (ps.bin, baner.bin, ec.cfg, ukps.cfg, and dummy_ec.cfg) might have some significance? Or is there some difference in the save file formats? Or... is it just JD not wanting to accept a save that originated from a Wii?
