I don't know who decided to do all this RenkoMari stuffs but I am here for it.

Also: applying for a Super Famicom tag.

I thought this was about Laplace transformation :/

What are you doing, put Kirby Superstar back in and play together, you useless lesbians!

The last page make me think that maybe Merry did something to the game. She may turn that fantasy to reality.

At first, I also thought it will be about Laplace transformation. Good thing it isn't. Just seeing the word "Laplace" already makes my head hurt. LOL

I actually thought that this was about the Laplace distribution, since it has more to do with random numbers than the eponymous transform.

My degree is really paying off.

The nerve talking about physics when you have a girl over!

In the end either Merry did turn fantasy into reality or simply disprove LD theorem but damn, this makes my degree shines

Thought that's Laplace's demon on start lol, because that's the only one related to determinism.


appearing on startup means there's no user input so no random values

... No? I mean, yes, you can do that? Just measure some physical quantities (most commonly temperature, or circuit electric noise) and take a few less significant bits, now you have some nice entropy to feed to your prng. That's basically how most cpus we use today generate random numbers.

... What am I talking about. It's an old-ass (no pejorative meanings intended) game console >:(

I mean the thing about these older consoles not having an operating system in the way we'd think of it is that they also don't have any built-in routines to initialize memory. The RAM is there and it's up to the game plugged into the system to do anything with it. RAM also doesn't immediately go to zero on power-off; see, for comparison, this bit about NES power-up state and examples of this causing issues with games.

This doesn't answer the question of whether or not there's any evidence within a Shin Megami Tensei cartridge of an intro sequence like this that might be triggered by a RAM irregularity. As entertaining as it would be to say yes, that doesn't seem to be the case. However, other games for the SNES did check game state at boot for anti-piracy purposes, and matching the urban legend would have been a fun way to implement such a lock.

I have no experience with retro gaming, but if such a sequence can be triggered, it at least needs to exist in the cartridge programming somewhere. Even though it might be interesting if game developers are to add an easter egg sequence like that and make sure it's never executed during normal operation, it probably won't be likely (why add an easter egg that's not going to be executed, sounds like a waste of ROM space).
Though, if it does exist in the cartridge programming, even if they're not programmed to be executed under any circumstance (like, wrapped by a if(0) ), if the control flow of program went haywire (like, jumped/returned to the start of this sequence) or something unintended happened (like cosmic bit flip), it could be possible in some case to trigger this sequence.
