bringing back to life a 900hrs save file

[a_random_stoner]

i play only mh3 rn and i'm using a usb connected ps3 Dplay controller and it works perfectly fine on 3.5, but now that i fixed my wii i'd like to import the save files but the contoller only ''works'' on 3.5, not on the latest versions (i've tried every single one and no one executes the inputs that i give while the game is running, same for the keyboard), so what can i do to import the save files from my wii to the game and then play it? i have 900hrs on it and it's my childhood game (and yes i'm stuck with the lagiacrus on single player)...
