How does one intentionally corrupt the save, forcing the game to load the backup? (HGSS)?

Question

I know that if a player's save corrupts (not the entire save file, but rather the most recent savepoint), then the game uses the second most recent savepoint to load the game. I intend on saving before choosing my starter, and then again at the red Gyarados, to SR it and find my SID. However, I kinda want to RNG manipulate for my starter, so I was hoping that there is a way to forcively corrupt the most recent savepoint, so I can return to the begining of the game, while knowing my SID?

Comments

I always thought the games kept one save file, and corrupting that one forces the player to start over. I also always thought that it's easier to get a shiny starter by RNG abusing while breeding the starter.

Answer 1

I believe shutting it down whilst saving does the job.

In general, you shouldn't answer questions unless you're sure the answer is correct.
