thanks a lot for the fast reply! i have read through the thread you pinned, now my only question would be how i invalidate this part of the file you mentioned? i downloaded a hex editor already but im not exactly sure what you mean by: "offset 0x40000 + GeneralSize, invalidate the previous 0xC bytes by arbitrarily replacing bytes with something else so it doesn't match a Gen4 save block footer" like i said im a noob when it comes to this so i would greatly appreciate it if you could explain it for dummys thanks in advance
