Virtualboy advance has 64kb sized saves, while my 3 in 1 +tool to work with my r4 makes 128 kb saves. I've tried renaming my 64kb vba saves to exactly the same thing as the 3 in 1 saves as but it just overwrites it with the 128 kb saves. I saw a save converter of some sort a few days ago but idk if thats what i need to use. any help would be appreciated. Also, anyone have a link for savesender? My old link died
