@alice going back in time probably just creates more timelines. we need to look ahead to the future instead of back- and dethrone biff, even if he does make electric cars and destroy websites.
You can have both Shirley? But you're always going to be limited either by the read/write speed of the USB stick or the USB protocol (possibly some glitchy backward compatibility software too though, I guess). Or the W/R speed of whatever it's interfaced with. I'm not actually sure where I'm going with this so will just hope you've got bored at this point and done something else instead.
