I have a SCSI2SD that was setup by someone else and then given to me I've been using it as is, but I went to copy an extension to the system folder and I can't find it anywhere it seems to be hidden somehow. The drive is configured for multiple OS but while all are bootable, none seem to have a system folder visible from within the OS. Is that a side affect of the way these work or how can I copy something to the system folder if it's not visible within the OS? I'm sure this is a dumb question so I apologize in advance.
