I am having a very odd issue after installing boot9strap and Luma 7.1. I don't believe this issue began until 7.1 was installed on my system, but I can't be positive that it is the cause. The issue is as follows: Some seemingly random titles on my o3ds console will simply boot into a black screen after the Nintendo 3DS or Homebrew intro animation plays. Some examples of affected titles: Pokemon Moon (Cartridge Copy) Super Smash Bros. For Nintendo 3DS (FS) Dead or Alive Dimensions (Personally ripped CIA) Various Homebrew Titles (Uninstalled them, can't remember which ones) Unaffected Titles: Any VC games Most digital 3DS games (Tested with Animal Crossing: New Leaf, New Super Mario Bros. 2 and Hatsune Miku Project Mirai DX for this) What I've tried to do to fix this: I was initially told that going to the eShop pages for games that were installed on my 3DS may resolve the problem before going into more detail that this was also affecting a cartridge based game. It did not help with the physical or digital games. I've also tried uninstalling most of my homebrew applications that were installed in case somehow one of them was causing an issue. No avail. What I think might be the cause: Conflicting files somewhere? I honestly don't have any good suspicion of what the problem is being caused by. I hope someone else might. What I am considering doing: Formatting everything. I really don't want to because I'm unsure if I'll be able to get B9S back afterwards. I have one of the DSiWare titles needed on the affected 3DS but no real way to send it off and get it back in the end of the process for save injection... I honestly am at a loss. If anyone has any ideas of what could be the cause of this and how I can resolve it, I'm listening. I also will try updating to b9s 1.2 and Luma 8.0 as I don't think that could make this problem any worse. Update: Installing B9S 1.2 and Luma 8.0 made no difference.
