[Darukeru]

Hi, sometimes booting a GBA installed cia, I get that error, I have to force it to power down pressing the power button. But trying again, the same game boots perfectly.
I´m using Luma 6.6 0b16d88 in a New 3DS XL 11.2.0-35U, A9LH installed.
My MicroSD card is a 128GB one with 64kb cluster size, and about 22GB of free space.
