Okay, it worked, but it worked strangely and gave me a scare for a sec. When I had uploaded my my save file in Spider-Man on PS4 and went back to the PS5, Spider-Man Remastered was nowhere to be found anymore. Instead a logo for Spider-Man PS4 with a lock next to it was there. Only when I put in the Spider-Man PS4 disc did it unlock and the logo turned into Spider-Man Remastered again. In the game I could now download my save to a second slot. Do I now always have to insert my Spider Man PS4 disc to play Spider-Man Remastered?
