I had used checkpoint with and both with ultra sun, ultra sun worked fine with that method. The first "save" being the one with "ultra sun" was from the SS cart. I mean the file is named Pokemon SS so I dont know how it had ultra sun in it and it was taken from the SS folder. I had tried another method that was using twl and yet still all my saves didnt work. I can try another method that's NDS/DSi tool but looking at the save file for twl its blank just like the most recent one linked before. So :/, my guess is that the cart just cant be read by anything due to it being a repro?
