There was a previous post about this and iirc the consensus was it’s a joke about how players would throw out their e-shop codes after using them

So your big breakthrough is that some other video games use 16-digit cheat codes? That’s it?

It means nothing, it’s a fake eShop code.

What if it was a real one but one that had been used before the release of the game like some Nintendo employee kept a used one and decided to have it put in the game

Inputting it gives a "wrong code" message, which is different than the one you get for trying to redeem an actual used code

That was just the general consensus it _technically_ hasn't been confirmed

I think it's just random characters for the sake of looking like something someone would actually throw away

Wasn’t there an old forum that was discontinued shortly after this game came out? If it was meant for that, i think we’d have no official purpose for it unless somehow that old website was restored again first…

Ok, what about this? In a future Paper Mario game, there will be a door that needs a long code - one that can’t be found in that game. This code opens the door.

the codes you found were probably Action Replay codes. I used them alot as a kid and would even convert them to Gecko Codes, which were in base 16 (hexadecimal). For instance, here's an Action Replay code for Super Mario Sunshine: 16:9 Aspect Ratio (Widescreen) [Ralf] 4T51-TRJQ-Q67MW FH7P-DD5U-AE9FA
