I saw it a few days ago, but didn't knew it was this issue.
Yeah thats what theyre saying. TiniVi also says this "OH. This is something I was able to replicate! It seems when there is no gamecard, arm9 doesn't comply. I'm sure there's a workaround, but for now that's the solution I guess."
EDIT: TiniVi just posted this a few minutes ago regarding the black screen issue "I think I found the cause, I'm working on a fix."
