You want a crash that either freezes the console, causes it to reboot, turns the console off or goes back to the desktop with no error code.

Thoes crashes are not captured by the normal crash/error handler which COULD be used as an exploit but rarely so. All depends why it crashed (buffer overflow and so on) and if the user can insert some data (e.g. corrupted save) into restricted/non game memory.

So in short if the game crashes and gives an error code the console already did garbage collection to make sure other parts of the system are not affected making it not exploitable (or near impossible)

It can be a random Bug because i didn' t edit / modded the save or other data. I'm not to 100% safe of this are a buffer overflow

Just because a game crashes does not mean it can be used for a exploit
I don't know how to recognize a exploitable crash xD

Unlikely, very few crashes are actually exploitable.
Even if it's exploitable, there's just about zero use for a secondary entrypoint these days since once you have CFW installed it doesn't matter.

I'm not that knowledgeable in therms of boot loading, but I'm kinda sure you need to find something like what I quoted above and find a way to overload it with a bunch of useless code causing it to load into a vulnerable state like frogminer for instance, then load your unauthorized applications.

Edit: Didn't mention the Sudoku exploit which deals with save editing overloading

If those were patched this wouldn't help since you'd still need an entrypoint in the first place to install the hacked save.
