I brought my Switch with Smash C2C2 to a small Smash group at my uni today. They played for 8 hours STRAIGHT and didn't get a single crash. And note that my microSD card is exFAT.
Atmosphere 0.7.5, Switch 6.1, using 25E crashed on my first play once i tried to go into "news" section in the right hand side-bar.
Nope. Been playing smash 25E since yesterday.
I installed the NSP by copying onto my exFAT SD card. The game consistently crashes during the opening cinematic, but I haven't been able to get it to crash anywhere else.
As an experiment, I switched to a FAT SD card that also has CFW, and I still consistently crash. So if there's an exFAT bug, it's causing the corruption during the installation of the game, not during normal play.
i had a crash when i entered the menu for mob smash
