I present the list of values of sp nostale
To change the value of your vision you need to look thick with cheat engine (4bytes = dword) value that is equal to the SP that you wore, tried to remove the value sp, refit it another try with a cheat engine (next scan) and you will find 3 values, change them with the values of the SP you want.
If you want to use thick yet feminine or new releases, you must add 128 to the value of sp.
Just play around with you, bye ^^
