Explanation of the issue:

When booting a European copy of Miitopia (00040000001b4f00) using Luma Region patching, it causes a prefetch abort, no matter what combination of Region strings I've tried (EUR EN, EUR EN EN 01, EUR EN EN, EUR EN UK, EUR EN GB).

The file is /luma/titles/00040000001b4f00/locale.txt like it's supposed to be, and none of the above strings that I've tested seem to prevent the crash.

Steps to reproduce:

  1. Create proper directories for region patch (titles directory, then titleid directory)

  2. Create locale.txt with only contents being "EUR EN"

  3. Launch game

  4. Crash

You disabled arm11 exception handlers. That disqualifies you.

TuxSH commented 7 years ago

Does it happen w/o region patch?

astronautlevel2 commented 7 years ago

@jupitteer I don't see where they disabled exception vectors. Also, they explain the exact issue they experience (prefetch abort) which you can only see with the exception vectors...

icefire82G commented 7 years ago

@TuxSH Yep, still crashes without the region patch.

This is loader crashing and not the game itself... Does it crash with "game patching" disabled? If so, the game is probably corrupted (seed wasn't installed properly or something).

icefire82G commented 7 years ago

Yep, it crashed when I turned off game patching.

Reinstalled the game and it worked fine after reenabling game patching and adding the proper patch.

Thanks guys!
