Nope. I remember cracking a tape game in order to save it on disk.
It uses a similiar technique than C64-games: It loads a fastloader into memory at normal (slow) speed, and overwrites a portion of the extended zero page. (if memory serves me right, it used the BSOUT hook at $0324)
Since BSOUT is called when the basic interpreter tries to output anything on the screen, it autostarts and loads the main game.
