I have once again misplaced my SD card reader.
@ifixcoinops that was the first thing I tried. If it's possible, it requires a different firmware than the one I'm running.
I ended up enabling SMB on my gamedad and doing it over the network.
@crazybutable I have a "computer lab" with fifteen old desktops, all of which had SD card readers at one point.
Our printer computer had an SD card reader. Our archival computer had an SD card reader. The studio Mac had an SD card reader. I had two in my bag. I had one on my desk. I kept one on the mantle.
I couldn't find any yesterday.
