Hacking Homebrew [Beta Release][Tester wanted] Kernel9 patch to speed up boot speed on high capacity SD card

is this....safe to use now?...

Testing this out with a 128GB SanDisk card, I haven't really noticed any increased speeds like the 2TB video that was only 4-5 seconds. I am also seeing some issues with mods that load files from the card, Smash NEOS crashed upon loading a stage.

no way to use this without a custom luma build, maybe a plugin ?

I wonder if it would be possible to reuse GodMode9's free space calculation (which is noticeably faster than Nintendo's code) during pre-boot, disable Nintendo's from running, and write the correct value in memory where Nintendo's would.

I haven't received any report of SD card corruption until now (and hopefully never in the future).

If you disable the patch (reject to apply the patch on boot) does it still crash?

Currently only way to use this patch is to use my custom luma or Nexus3DS (disabled by default, enable in advanced config) v0.3.0 or later.

I got the PR for this, however it was not faster

v1.3 is here!

v1.3 (beta version) (based on Luma3DS v13.4)
- Added free space probing using fatfs (runs only on explicit user request).
  - You can trigger it by Luma3DS menu -> System configuration -> Recalculate free SD space on next boot.
