These are not instructions, just an animation of a cat walking into his house.
How I did this: My idea was to load a 13Feb05 project to 23Jan06, then to 13Oct06, and then to Scratch 1.4, and then Scratch 3.0. So when I loaded the 13Feb05 project to 23Jan06, I had to replace every "when I receive message [go]" block with "when green flag clicked", and all the gliding blocks turned red, but they still worked. So, I made them blue by swapping the red ones and inputting the same coordinates and times. And when I loaded the 23Jan06 project into 13Oct06, surprisingly, nothing happened. And when I loaded the 13Oct06 project into Scratch 1.4, also nothing happened. But when I tried to share it online to Scratch 3.0, it failed for no reason. So, I did the save as method and loaded it in Scratch 3.0, and it worked. So I successfully loaded a 13Feb05 project to Scratch 3.0!
