Memory card confusion - Raspberry Pi Forums

hey all.

bought 64gb sdhc memory card , had formatted fat32.

put retropie-3.5-rpi2 image onto , booted.

went fine.

anyway, i'm watching youtube video , guy says need usb stick.

can't use 64gb sdch card store rom files or ripped cds?

thought usb ports controllers, keyboard , mouse.

don't understand why bought such large, internal memory card if i'm going using 2 gigs of it.

ahead if can explain confusion on this.

cheers.

yes, 64g not necessary.
buy usb stick transffer files.
