If you had previously played a game but broke the disc, what would happen if you installed the same game using this method? Would you be able to use the old save file? If not, could you get a new disc and have two separate saves (one from wup and the other from the disc)? Or, would it just erase...
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
