Im trying to do the same but when I type

rm /home/pi/pimame/roms/nes

I get the message cannot remove as it is a directory? any ideas, thanks

Can it run rom.s from a memory stick

@seagull - yes, you can run roms from a memory stick.

@Conno123009 - it's mostly the same, but with formats like ntfs you have to install drivers. I kept my thumbdrive formatted as ntfs so that I can still plug it into my windows machine to transfer bulk files faster than ftp. I had to use the fstab method because I was getting chown errors and the only tutorials I could find said to use fstab :) . Also, I like to use the UUID since I am constantly changing what is plugged into my usb, some things load sooner than others and may take that sda1 slot. Once I settle on a final setup for my arcade, I'll probably re-format to a unix based format though, I hear it gives you much better read/write speeds.
