I'd like to get a fairly good sized micro SD card to store backups of games that went missing from my collection, as well as lots of SNES, PC Engine, NGPC, and GBA roms. I was considering getting a 128 GB card to be safe, but I heard cards of that size and higher cause slowdowns as well as unfixable glitches. If this is true, then is a 64 GB card large enough to store all of this with a bit of wiggle room left over?
