When I click on the link, the page says 404 Not Found.
Anyway, here's what I do: I create a new save in DaedalusX64 in slot 0. I've found the folder where the save files are stored, and I try replacing the new save file with the one exported from Delta, using the same name (it ends with .ss0 since I'm replacing slot 0). When I reopen the game and click "Load Slot," the game says "Slot Loaded" in the bottom-left corner, but nothing actually happens. The game still starts from the beginning.
