Since I haven't thoroughly tested HuCards it's happened a few times playing CD-ROMS (i.e. Super Raiden & Spriggan) where the system will randomly reset to the main menu. It's as if it looses connection with reading the card after some levels passed.

I'm wondering if it's my file structure or size of sd card? Files are organized by alphabet and by HuCard or CD-ROM (cd game files in each individual folder) using an 256GB Samsung Evo MicroSD card. Anyone else experienced these random in-game resets???
